Rechargeable Camera Batteries: What You Need to Know
By: Gadget Peak
Tags: Battery, Gadgets, Rechargable Battries, rechargeable camera batteries, Rechargeable Battery

When purchasing digital cameras, one of the essential considerations that you must think about the model is what kind of rechargeable camera batteries does it use?

There are two major classes of batteries that are employed by a variety of camera models. Every battery type has its own benefits and while it mustn’t be the deciding factor when selecting a camera model, it is still helpful to learn which one is more ideal for particular situations. Here are some data about rechargeable camera batteries that you may find valuable when choosing a camera.

Most camera models nowadays come with proprietary rechargeable camera batteries. These are lithium-ion batteries that include a charger so that all that you require is already within the package. Once the battery is drained, you can just load it in the charger and once it is finished charging, you can shoot picture again. Apart from being practical to use, proprietary lithium-ion rechargeable camera batteries have a relatively low self-discharge rate which is estimated at around 5–10% per month, compared to nickel metal hydride’s 30% per month. Hence proprietary rechargeable camera batteries boasts a very long shelf life, which is ideal if you do not have to use your camera regularly.

Alternatively, the other class of battery that may be used for cameras are off-the-shelf batteries. Cameras typically require CRV3, CR2, AAA, and AA battery sizes. The main thing that you can gain from this class of battery is the flexibility it can give you. While proprietary rechargeable camera batteries are very convenient and ready to use, buying a spare one is actually very expensive, so most of the time, people do not bother buying an extra one.

Meanwhile, cameras that utilizes off-the-shelf batteries can be operated on both disposable and rechargeable camera batteries. While rechargeable camera batteries are more recommended for cameras, disposable camera batteries can be a cheap solution if ever you run out of energy and still need to shoot some more. The best class of rechargeable camera battery is the nickel metal hydride which contains a high energy density that is best for the high power requirements of digital cameras. Unfortunately though, in addition to the batteries, you also have to purchase the charger for off-the-shelf rechargeable camera batteries.

7 Signs Your Car Battery Is About To Die And Needs To Be Replaced Luisa Nov 10, 2019·3 min read

Without a battery, your car simply isn’t functional. One of the most inconvenient things in life is when your car battery suddenly dies unexpectedly! This can delay you to work or make you miss an important appointment!

But the good news is… there are several ways to know if your car battery is on the verge of dying and needs to be replaced. And in this article, we will go over 7 signs your car battery is about to die and needs to be replaced or reconditioned.

1) Slow Cranking

When turning the key, if your car turns over for longer than normal or takes a while to “catch,” it often is because the battery charge is low. While the starter can be the culprit, most of the time the battery is to blame. If this is happening regularly, it’s a good sign your car battery is going bad and it may be time to replace your battery or recondition it.

2) Check Engine Light/Battery Warning Light

The check engine light is always a good indication of something off with your vehicle. The battery power is weak will trip the check engine light. If your check engine light is on, be sure to check the battery power level.

Additionally, newer cars have a battery light, similar to the check engine light. This will only light up if there’s an issue with the battery.

3) Age

A car battery lifespan, in perfect conditions, is about five years. If your battery is coming up on the five to six-year mark it’s time to start looking for a replacement or recondition it to give the battery a new life.

4) Electrical Component Issues

One sure sign that your battery is beginning to fade is if electrical components are struggling to operate (such as lights, windshield wipers, power locks, and windows).

5) Swollen Battery Case

If you look under the hood and your battery case looks swollen, bloated, or malformed; it is a sign that temperature has affected the chemical components of the battery, shortening the lifespan.

6) Smell

If you smell sulfur or rotten eggs under your hood, this is often a symptom of leaking battery acid. This can damage other engine components if not addressed quickly. If you notice this, you can either bring your battery into a shop and have them look at it or you can use our reconditioning steps and do it yourself.

7) Multiple Jump starts Needed

If you’re having to jump your battery to get your car started more than three times a week, it’s time to replace the battery or recondition it. Excessive jumping can also damage other systems, so it’s best to get the battery replaced or to fix the battery yourself.

Regular maintenance is important to extend the life of your car battery (and also your vehicle). And if your car battery is showing any of these 7 signs, you know that your battery should be replaced or reconditioned before your car no longer runs.

And if you want to take it a step further… you can learn how to double or even triple the life of your car battery by watching this presentation now.
Are Lithium-ion batteries sustainable? Is there an alternative?
By: Sustainability Enthusiast
Tags: Electric Vehicles, Energy, Sustainability, Battery, Lithium Battery

Sustaniable batteries are necessary for a brighter future.

The use of lithium-ion (Li-ion) batteries in majority of our gadgets to electronic vehicles says a lot about its commercial viability and consumer trust in them.

However, Li-ion batteries contain toxic substances like cobalt and lead, and other rare minerals that are difficult to mine, such as manganese and nickel. Glencore, the biggest producer of cobalt in the world, has predicted that with the increased demand for electronic vehicles, the demand for cobalt will shoot up by three times by 2025. Given most of the world’s supply chain in these metals is owned by China, many countries will face a crucial dependency for their energy storage solutions.

A possible solution to the above scenario is the launch of a sustainable alternative to Li-ion batteries. This is where sodium-ion (Na-ion) battery technology comes in. There has long been research going on in this field to make Na-ion cells available for commercial purposes. The benefits of using sodium in batteries over other chemicals such as lithium or lead acid are many. Some of these benefits are that —

Sodium is abundantly available and Na-ion can be extracted nearly anywhere.

2. It uses cobalt-free cell chemistry with no graphite, copper or lithium.

3. The costs of precursor materials are low

However, the concern has always been its performance as compared to Li-ion cells.

Are there performance effective Sodium-ion batteries currently available for sale in the market?

Several companies have intensely invested in R&D to launch performance effective Na-ion batteries commercially and have also been successful in doing so. Some of them are the French start-up called Tiamat, Faradion & Oxis Energy in the UK and the China based HiNa Battery. Out of these, for Faradion the cycle life for stationary energy storage applications is claimed to be 3000 cycles and improving. They also seem to lead the world market in manufacturing and system designs for sodium-ion batteries. They produce Na-ion batteries on the same manufacturing lines as Li-ion. This makes it cost-effective as no additional equipment is required. Their advanced non-aqueous Na-ion batteries have also been demonstrated to be safe. performance effective and applicable in e-bikes and e-scooters.

So, is sodium the sustainable answer to cleaner alternate battery sources?

Since sodium is much more plentiful, Na-ion batteries could well be the most sustainable and eco-friendly among other alternatives. We could say that Na-ion cells are the future of clean energy.

How to increase Battery life of Laptop

Quick answer:

No, Charge it till 60–75 then unplug then charge it again after it falls below 30%, To me this seems like the best strategy as no one the industry seems to agree on one thing, and that is what I try to follow.

Explanation:

Three things reduce battery life-

Charge/discharge cycles

Voltage level

High temperature, over 30 degrees Celsius

I’ll not explain these terms but use them in explaining my strategy as they are the driving parameters.

So, battery achieves maximum discharge cycles when it is charged to 3.90 V/cell which means 60–65%. every .10 V above that the discharge cycle falls to half. So it seems like the best Idea to stay around 60%.

Below 60% will mean that we’ve to charge it twice the no of times we do at 100% so that’s not good. At 100% charged the discharge cycle is only around 300–500 which is way way less than what is at 60–65%(2400–4000 cycles).

On top of that Heat also affects the battery life. Since we don’t have much control over the surrounding temperature we must try to keep our laptop’s temperature as low as possible.

Now since we’ve already eliminated the idea of charging the battery to 100% you might be wondering what if you don’t let it discharge at all. i.e. keep it plugged in all the time, which most people also seem to advocate for as well. That seems like a good idea and even Dell says that you can keep it that way but it does come with a trade-off. Keeping the laptop plugged in will increase your laptop’s temperature which is again enemy of your battery.

In my case it increases the temperature at least 10 °C when i’m not even doing much. Also, at the same temperature battery charged at 40% lives far better than a 100% charged one after a span of One Year so that is also one reason.

Life Span of Product:

My one last argument is how long do you want to use that product?

Most gadgets are replaced after 2 or 3 yrs at max so if we do the calculation-

1yr = 365 days => 3yrs = ~1100 days

Even if you charge your battery twice everyday, each day for 3 years you still use about 2200 discharge cycles. which means anywhere between 60–80 will give you that many cycles and even if your battery capacity degrades year on year we can assume that the plan will workout for at least three years given that no one is going to charge twice every day for 3 years. It can be more than 3 some days and on some days you might not even use it. So, If I keep the temperature low and charge it no more than an average of twice/day than it sounds like a good plan to follow.

How to Increase the Life of a Jump Starter
Tags: Portable Charger, Battery Charger, Battery, Jump Starter

The portable jump starters are the needs of every vehicle, wherever you are going travel worry-free, thanks to advanced durable long lasting Li-ion battery that gives power to every jump starters.

Portable jump starters are the latest product from Imazing who are committed to building a quality product with certified safety measures along with durability and toughness. A majority of the consumers use jump starter, but do you know there is the common issue everyone face after a limited time is ‘Quick Battery Drain’ although we agree after a limited period of time Li-ion battery start to age by time and lose its capacity. Don’t be upset; here we are going to tell how you can manage a good battery life of your jump starter.

Here in this article, we will talk about what measures you should take to increase the life of a jump starter.

Are you ready for it? Let’s go:

• Use Frequent

With frequent use, the battery capacity will be maintained. As a result, it won’t lose its capacity. Consumers normally use after a long period of time this could be a reason to degrade its capability. Use it always when need.

• Full Charge

Unlike smart phones, the jump starter is equipped with Li-ion batteries, always charge fully to get the maximum potential of power during a jump start your car.

Note- Charge after every use because it can only jump starts your vehicle if it is fully charged.

• If its heat avoid its use

Sometime you may have observed that your jump starter is hot to hold. In this case, avoid using and wait till it gets cool.

• Use Quality Cables

Always use Hi-Quality of wires, which should not be more than 3 feet long, a torn cable is unsafe to jump-start your car. A split wire may result in power loss and additional pressure on jump starter which may cause a short circuit.

• Quality Matters

Do know if you buy a cheap quality of jump starter, there is a higher risk of safety because local brands don’t have R&D team who do research and analysis of the upcoming products. Therefore, those brands ignore safety measures. A better quality will give maximum performance with high quality tested battery.

These are the few essential points you should remember, we know batteries age by time, but by following these measures, we can utilize the maximum potential of the battery for a longer time.

Apart from this, the battery performance also depends on the usage and maintenance, how you take care of the jump starter. If you use roughly, or you expose to direct sunlight, then there is a higher chance that the jump starter battery will degrade.

How to Check the Fire Stick Remote Batteries
By: Sofia Ada
Tags: Battery

Hello, all of, if your amazon firestick remote not working at all, you need to check the Fire Stick remote batteries to fix it. The Amazon Fire Stick Remote is a power-hungry accessory. After using FireStick for a while and running into battery exhaust problems for more than just a few minutes, I can safely say that if the remote isn’t working, there’s a big possibility that the battery She has been out of charge. The battery deteriorates without warning. If your fire stick remote suddenly stops working I would bet my battery.

amazon firestick remote replacement

Honestly, I’m not sure yet why the remote consumes so much battery. Sometimes, the battery dries in only a few weeks. The Fire Stick Remote uses Alexa, voice recognition and voice command technology. Some people want to blame Alexa. But, it is not that the remote is always listening. To hear it you have to press and hold the Alexa button on the remote.

Regardless of the reasons, the only possible solution is to use good quality, alkaline batteries and maintain the parts. Alkaline batteries are the best by far and they work your fire stick remote the longest. However, do not buy any alkaline. Buy branded from a reputed manufacturer.

A week ago, I would also have recommended a rechargeable alkaline battery if I had not encountered a malfunction. One of the remote batteries leaked and a white remnant accumulated on the connector. Even the brand-new battery did not work until I exhausted the white material.

Therefore, forgive me if I am not sure of the rechargeable battery. This also brings me to the point that it would be a good idea to remove the batteries and check for any residual deposits from battery leaks on the connectors. Cleaning them may cause your fire stick remote to work again.

And, there is one more thing I forgot to mention. You probably already know that batteries have (+ ‘(plus) and’ — already (minus) ends. Connectors in the battery compartment also have + and — sides. The + edge of the battery with the + of the connector Must be aligned (and the minuses will be aligned automatically). I put the batteries incorrectly and have found myself struggling with the remote for a while. Just insert the new battery.
Naptime 7.2
By: Francisco Franco
Tags: Android, Battery

This looks like a small release, but it packs one of the most requested features, the ability to block some settings to be applied when the device is under some sort of high performance location access (the likes of Google Maps while using navigation).

Took me a few days to find a reliable way to detect if Android was doing location queries consistently so after that was out of the way the rest was a piece of cake to implement.

In this case the “Android battery saver” was a challenge because I didn’t remember it disabled any location access during screen off, so for a few hours I couldn’t figure out why the location detection producing the results I looked for, so naturally once I found about it that was one of the settings we had to block when location was detected.

There was also one important fix to the automatic “Android battery saver”. On previous releases Naptime would ignore if you have the battery saver turned on before running the doze routine, and it would automagically turn the battery saver off after the user screened on. Now it respects the setting properly!

Made the intent dialog a bit more transparent. Before I got questions about if it was working/not working because it didn’t reflect the change in the UI, but now it does.

More features are coming so stay tuned!

The Different Uses of Lithium
Tags: Stock Market, Investing, Power, Battery

EVs would need much more batteries than we can comprehend. Lithium-ion batteries have been around for decades, as you are probably aware. They are currently powering billions of devices and will continue to do so during the day. It appears that electric vehicles are having traction. And this has far-reaching consequences for a related industry: lithium mining and processing. A typical EV battery cell contains just a few grams of lithium. This equates to about a half teaspoon of sugar. Around 5,000 battery cells could be used in a typical electric vehicle. From there, a single EV contains around 10 kilograms (22 pounds) of lithium. Around 90 electric cars can be built with a lot of lithium metal. sponsored post. Moreover, it was said that the soaring global demand for electric vehicles, consumer electronics and renewable energy storage systems is sending demand for lithium to historic levels making these other companies’ potential for bringing lithium supplies to market potentially even more valuable. (1) Definitely, the Lithium could possibly use in many ways. Explore more potentials of Lithium with this one.

Lithium is a common element, not a rare metal. There’s plenty of it, so it’s hidden under the earth’s surface. To extract it, you’ll need mines and, in some cases, large-scale operations, which can take years to investigate and set up. In the 2020s, millions of battery-powered vehicles will be on the track. And they’ll need more and more lithium every year. Meanwhile, lithium production is being restrained by record-low lithium prices. Lithium batteries are now produced from a variety of different materials and chemical compounds. And the structure of these groups varies depending on the technologies used. On the other hand, I found out these other companies, it was said that they are one of the few that has both the resource and the technology to make lithium from direct brine process with outstanding results has the potential to produce battery quality lithium for batteries. (2) That is an amazing characteristics of a Lithium firm right? You could find out more interesting information about them here.

The demand for lithium would increase. One encouraging sign for lithium producers is that they would trade more lithium. Check the disclaimer on my profile and landing page. Then, as demand for lithium increase, so would costs, allowing new mines to be built to meet the increasing demand from electric vehicles. Another reason to be optimistic about lithium miners.

Electric cars will take another step forward because of the existence of “it” Alan Jack Jul 5·2 min read

what is it? Yes, it is a lithium metal battery.

Such batteries — the goal of research groups the world over — are seen as an important part of the solution to reduce the effects of climate change, and scientists are exploring a dizzying array of options.

One solution on the horizon is a lithium-metal battery for electric vehicles. These batteries hold almost twice the energy of their widely used lithium-ion counterparts, and they’re lighter. But lithium-metal batteries in the laboratory have been plagued by premature death, lasting only a fraction of the time of today’s lithium-ion batteries.

Now, a team of scientists at the U.S. Department of Energy’s Pacific Northwest National Laboratory has created a lithium-metal battery that lasts for 600 cycles, far longer than other reported results. That means it can be fully charged and discharged 600 times before it dies.It’s a big step forward for a promising technology, but lithium-metal technology is not yet ready for prime time.

The progress on lithium-metal batteries has been substantial, thanks to the Battery500 Consortium. The goal is to increase the amount of energy packed into a long-duration, safe, affordable battery. More energy per pound of material translates to a lighter vehicle that can go farther on one charge. Today’s electric vehicle batteries are in the neighborhood of 200–250 Wh/kg; Battery500 is aiming for a cell level of 500 Wh/kg.

Although this effect has been achieved now, there are still some problems that have not been resolved. In particular, lithium metal batteries have safety issues that must be resolved. This is a problem that the Battery500 team is working hard to solve.

Next, let us all wait and see! Looking forward to its success, ushering in a new era for our electric vehicles.

[Linux] Play a warning sound when your laptop battery is low
By: Kasun Siyambalapitiya
Tags: Laptop, Linux, Ubuntu, Battery, Laptop Battery

When working on a big project or when watching a movie or a TV series in an extended display, all of a sudden you might have ran out of battery and your laptop got shut off or goes to sleep or hibernation. This is very bad for the battery in terms of its lifetime and if your laptop has a mechanical hard drive (not SSD) sudden power off could damage the data in it.

What if your laptop could give you a warning sound when your battery drops a certain value,continuously ( ex: every 5 minutes) so that you can plug in your laptop at your earliest. Well this is very easy and will take about 5min to configure 😍.

Download a short warning sound from anywhere on the Internet. (if you like you can even play a whole song 😀 but remember, that could drain your battery even more if you are not near it to plug it back). Install the command line music player `mpg123` by running the following commands in your terminal.

sudo apt-get update -y

sudo apt-get install -y mpg123

3. Create a script file to play the downloaded music if your battery percentage is less than 20 (you can customize this value to anything you want 😀 ) and save it in a desired location with executable permission.

#!/bin/bash # You need to export this environment variable in order to play sound from cron

export XDG_RUNTIME_DIR="/run/user/1000" currentBatteryPercentage=$(upower -i /org/freedesktop/UPower/devices/battery_BAT0 | grep "percentage" | awk '{print $2}') currentBatteryPercentage=${currentBatteryPercentage/\%/} if [ $currentBatteryPercentage -lt 22 ] then mpg123 /home/kasun/Music/apx_battery_low_aler.mp3 -l 2 fi

Note:

If upower is not installed in your system run the following commands for installing upower .

sudo apt-get update -y

sudo apt-get install -y upower

Replace mpg123 ‘s argument with the path to your downloaded music file (mine is located at `/home/kasun/Music/apx_battery_low_aler.mp3`)

4. Open your crontab file for editing by running the following command in terminal.

crontab -e

Fill in the following to execute our script for every 5min.

*/5 * * * * bash /home/kasun/Documents/Scripts/battery-low.sh

Note:

Provide the path to your script file after the sh command (mine is located at `/home/kasun/Documents/Scripts/battery-low.sh`)

command (mine is located at `/home/kasun/Documents/Scripts/battery-low.sh`) You can change the scheduled time to anything you want.

Please refer https://kb.iu.edu/d/afiz for more details on the crontab .

5. Save the crontab file.

It’s done 😊

Cheers !!!
💻 — 🔋Get Laptop Battery Name and Battery Power Status using C# Console Application
By: Jay Krishna Reddy
Tags: C Sharp Programming, Dotnet Core, Battery, Charging

First of all, Let me just explain to you in short about WMI & Win32_Battery!

What is WMI?

Windows Management Instrumentation(WMI) is the infrastructure for management data and operations on Windows-based operating systems.

You can write WMI scripts or applications to automate administrative tasks on remote computers but WMI also supplies management data to

other parts of the operating system and products.

What is the Win32_Battery Class?

The Win32_Battery WMI Class represents a battery connected to the computer system.

Let’s create a simple Console Application in Visual Studio

Click on Next -> Button

Give a sample solution name and then click on Create -> Button.

Add the System. Management package into our project.

System.Management Namespace:

project Provides access to a rich set of management information and management events about the system, devices, and applications instrumented to the windows management Instrumentation(WMI) infrastructure. Applications and services can query for interesting management information (such as how much free space is left on the desk, what is the current CPU utilization, which database a certain application is connected to, and much more), using classes derived from ManagementObjectSearcher and ManagementQuery or subscribe to a variety of management events using a ManagementEventWatcher class. The accessible data can be from both managed and unmanaged components in the distributed environment.

Program.cs

using System; using System.Management; namespace BatteryPercentage { class Program { static void Main(string[] args) { // Title Display Console.Title = “Info about Laptop Battery”; //Retrieves a collection of system management objects based on the below query! ManagementObjectSearcher mos = new ManagementObjectSearcher(“select * from Win32_Battery”); foreach(ManagementObject mo in mos.Get()) { // To print the Battery name Console.WriteLine(“Battery Name\t:{0}”,mo[“Name”]); // To print the Battery charging status Console.WriteLine(“Charge \t\t:{0}%”,mo[“EstimatedChargeRemaining”]); } Console.ReadLine(); } } }

Run the application to get the result of the battery name and battery status.

C-Rate of Batteries
Tags: Battery Life, Electrical Engineering, Drones, Battery, Electronics

Let's Explore

For example, a cell having a capacity of 20-ampere hours should be able to deliver 20 amperes of current for one hour or 2 amperes of current for 10 hours. The C rate may be a way of normalizing electrical current in line with a cell’s nominal capacity.

Fig 1: A typical battery with its few specification details. [9]

The capacity of A battery is often rated at 1C, meaning that a charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for 2 hours, and at 2C it delivers 2A for a half-hour. Losses at fast discharges reduce the discharge time, and these losses also affect charge times.

A C-rate of 1C is additionally referred to as a one-hour discharge; 0.5C or C/2 is a two-hour discharge and 0.2C, or C/5 is a 5-hour discharge. Some high-performance batteries are often charged and discharged above 1C with moderate stress. Table 1 illustrates the typical times at various C-rates.

Table 1: C-rate and time of charge or discharge 1Ah Battery cell. [1]

When discharging a battery with a battery analyser capable of applying different C rates, a higher C rate will produce a lower capacity reading and vice versa. By discharging the 1Ah battery at the faster 2C-rate, or 2A, the battery should ideally deliver the full capacity in half-hour. The sum should be the same since the identical amount of energy is dispensed over a shorter time. In reality, internal losses turn some part of the energy into heat and lower the resulting capacity to about 95 per cent or less. Discharging a similar battery at 0.5C, or 500mA over 2 hours, will likely increase the capacity to above 100%.
Handling Thermal Runaway at the Pack Level

ER6 Solution

Basically, the Roewe ER6 pack design adopts three solutions:

1. A complete fireproof cover within the pack

As shown in the figure below, this design uses a complete fireproof cover over all of the battery modules. The main purpose is to prevent flames from spreading when a single cell undergoes thermal runaway. This prevents the upper cover from being punctured and allowing oxygen to diffuse in during the process.

The fireproof cover consists of two layers:

One layer is a silicone-based composite material (which hardens into a semi-inorganic material with excellent thermal insulation properties at high temperatures).

The other layer is a very thin fiberglass material (to enhance the overall strength of the ceramic layer and prevent the material from falling apart while it is being formed).

An upper cover over the fire proof cover is constructed from an aluminum alloy sheet. The combination of a fireproof ceramic and a sheet metal alloy prevent the battery cover from melting during the high temperature and high pressure eruption caused by a cell thermal runaway.

Figure 1. Overall fireproof cover

2. Exhaust gas isolation and explosion-proof valves

The fire proof cover allows the hot exhaust gas to pass through the exhaust channels in the battery pack and exit through the explosion-proof valves on the body. Four one-way spring-loaded explosion-proof valves (see image) are placed on the outer edges of the pack, which enables large quantities of gas and heat to be exhausted in the event of a thermal runaway. A thin layer of steel is added to the inside of the explosion-proof valves to protect them from direct exposure to the high-temperature exhaust. The high-temperature gas passes through the exhaust channels and is blocked by a protective steel sheet before reaching the exhaust valve, which allows the temperature of the exhaust gas to be controlled to a certain extent.

Figure 2. Multiple explosion-proof valves

3. Additional heat dissipation for cell thermal runaway

When the battery management system’s (BMS) real-time monitoring detects that a thermal runaway may be occurring, the battery pump will be run at full speed. With the aid of thermally conductive materials, the excess heat will be quickly transferred from near the thermal runaway cell to other locations in the battery pack, which effectively reduces the temperature.
How long does the battery of Kindle Paperwhite lasts?
By: Albert Mark
Tags: Battery

The Best answer for this question would be — The Kindle Paperwhite has a battery life of around 28 hours, from fully charged to fully used. However, how long these 28 hours last depends on how you use them. In addition, the battery life can be extended with some helpful tips and tricks for saving energy. Read our best article on kindle wont charge to know more about the charging thing.

How long will my Kindle Paperwhite battery last?

While the standard life of a Kindle Paperwhite battery from fully charged to dead dry is around 28 hours in total, the life of this battery can vary based on usage. For those who just read a little light every now and then, a month or more can pass between plug-ins. For those who keep their device on and constantly active, it means a solid day of use, possibly less if additional functions are constantly being performed.

While it has a shorter battery life than previous models of the Paperwhite, our previous review found that it “contains more LEDs that allow for more even lighting when reading at night or under artificial lighting”. This trade-off of additional LEDs for shorter battery life means the device is much more user-friendly. How to fix Kindle fire won’t connect to wifi issues.

How can I extend the battery life of my Kindle Paperwhite?

If you are worried about the battery life of your Kindle Paperwhite, don’t worry. Fortunately, there are a few ways you can get the life of your Kindle Paperwhite longer with just a few changes to the default settings.

1. Turn the backlight off or off completely when you are not reading in the dark or in low light. Screens and backlights are typically the worst causes of battery loss.

2. Connect your Kindle Paperwhite to a computer when downloading new books. Not only does this give it a bit of juice, but it also uploads the files with less energy and delivers them over USB rather than the device’s WiFi.

3. When you’re not using your Kindle Paperwhite, shut it down completely or put it to sleep for a more responsive restart.

4. Do not store your device in places that are too warm or too cold, as this can lead to a loss of battery power.

5. Let the battery run out or run low as often as possible. Overcharging the device will ultimately reduce the overall battery life.

Conclusion

If you continue to have battery problems, the problem may be with the battery itself. If your device is not under warranty, replacement batteries can be purchased from third-party suppliers. you can also tell us if your kindle paperwhite frozen or Kindle wont charge.

You can’t get more monstrous than [Antonio] Sanchez, Calauan ex-mayor, Marian devotee, rapist. Dick Israel played his character in Humanda Ka Mayor!: Bahala na ang Diyos [1993], the exploitative Carlo J. Caparas movie version of the crime. Israel, a talented and dedicated actor, has been raping women in Filipino movies for half a century now. Dick’s signature leering face dominated the movie poster. When terror-stricken Sunshine Cruz and her friend Jeffrey Santos saw the mayor’s insane Divina Valencia wig, they knew they were in deep shit. (Can somebody tell me what Kris and Aga are doing in the poster?)

In 1993, when Mayor Sanchez and his men raped Eileen and killed her and her friend Allan, there was no doubt among Filipinos that the crime was absolutely unpardonable. And so when you have a senator today who used to be the chief of the national police and executor of Duterte’s drug war, who says it’s okay to release him; that everybody deserves a second chance; and you have Filipinos agreeing with him — we know we’re in deeper shit.

To those of us who grew up in small towns, we learn about power and what it does to the powerless in a very personal and straightforward way. Patronage politics is deeply-rooted in Filipino culture because it is played out in the smallest unit and passed on — through strongly-guarded family values. Family is a sacred cow in the Philippines, promoting patriarchy. TATAY Digong, the President himself made it very clear, mayors first.

(Watch Badil — if you haven’t yet — and the other films of Chito Roño and Rodolfo Vera. No other movie illustrates these gravely imbedded connections than the stories played out in these communities. It’s like Kansulay in James Hamilton-Paterson’s America’s Boy, an outstanding book that I think more people should read.)

Duterte and Sanchez. How depraved you must be to think that your position of power as mayor entitles you to the bodies and lives of young people as gifts? When you and Senator Bato says it’s okay to receive gifts, but no more than 100,000 pesos, it makes me wonder — who gave you the right to put a monetary value on a human being and their future?

If you still support Duterte, and Senator Bato, who says that Sanchez deserves a second chance, you should be worried, and you should be asking yourself what Duterte and the likes of Mayor Sanchez have turned you into. For what? For a chance to enjoy the spoils of power? We’re a nation of delusional and pitiful little kings. Ito ang trahedya ng mga DDS, little kings all the way down.

NO TO THE RELEASE OF SANCHEZ!

The best way to send money online to the Philippines from Australia in 2019 Rita Aug 22, 2019·2 min read

Currently, Filipinos are the third-largest Asian Australian immigrant group behind Indian Australians and Chinese Australians. According to the 2016 census, there are over 232,386 Filipino Australians.

So, there are hundreds of thousands of Filipinos have a demand to send money back to the Philippines. and there are lots of transfer companies which only specialize in sending money overseas, but do you know why they trust Epay for sending money from Australia to the Philippines?

Because you can send for free and get ₱35.00 per AUD on your first transaction.

Save on fees To send 100 AUD, 1,000 AUD or 10,000 AUD, the transaction is always 3 AUD. If you use WorldRemit or Transferwise, you can never get such a low fee. If you don’t believe it, see the picture below.

This is the price of Worldremit. It takes about 9 AUD to send 1000 AUD. and if you send 10,000, it cost 149 AUD!

and this is the price of Transferwise. It is more ridiculous, send 1000 AUD to the Philippines costs 17.46 fees!

Great Philippine Peso exchange rates Epay provides lower fees and competitive exchange rate as you can see in the above pictures. A high exchange rate saves lots of money for you in international money transfer process. Sometimes you should pay more attention to it than the fees.

On time Epay promises that they can make the funds arrive within hours or 1 day because they have cooperative banks and remittance agents in both Australia and the Philippines.

So, I definitely think that Epay is the best way to send money online to send money from Australia to the Philippines. No matter in the aspect of the transaction fee, exchange rate or the transfer speed. It is worthy to try it now!
“What is photojournalism and where is it going?”
By: Maro B Enriquez

The expression “the pen is mightier than the sword” has been used time and again to illustrate the power of words.

This, I believe, can be best exemplified by journalism, which, if executed well and with the right intent, has the power to change or shape people’s lives in significant ways.

But perhaps it’s about time that the saying be updated to show that photographs and images have power, too.

One specific incident comes to mind when I think of how photojournalism can create remarkable change in the human experience.

Back in 2017, the Philippine Commission on Human Rights, along with a small group of Filipino journalists, discovered a secret jail cell tucked away in the Manila Police District Station 1. The cell’s discovery caused a furor, mostly because there was hard, albeit intangible, evidence — all caught on camera and immortalized in photographs — that police were illegally and inhumanely detaining prisoners.

But what if no photographic record was made that day?

The public probably would have needled the prisoners to provide concrete proof that their experience was, in fact, real; because “to see is to believe” (as explained by Julianne Newton in her essay).

It is in this particular moment that images have made more impact than words.

And it is for this reason that local photojournalism needs to keep breeding new photographers who will make sure that all the important parts of history are recorded and made available to the public, and that those in power will be kept in check.

With all the new and affordable technology coming out continuously, (which makes the craft available to more people, like those in small communities), I think photojournalism will remain alive and well for generations to come.

RESPONSIBLE MARITIME GOVERNANCE
By: Wilfredo Tamayo
Tags: Philippines, Coast Guard, Maritime, Governance, Seaman

It is said that the key ingredients in the effective performance of agency functions are the ability and commitment of its leaders or unit commanders to manage its activities responsibly taking into consideration the vital mission the unit has to perform against the reality of very modest budgetary resources and rigid fiscal and accounting regulations. To achieve this, the following actions are considered priorities: The Command will continue to embark on programs and activities that will further enhance the morale and welfare of Coast Guard personnel. Continuing implementation of programs that will enhance operational efficiency through systems improvement and avoidance of wasteful pratieces. Institutional of the so-called leadership by example. Institutional of the principle of Command Responsibility. Strict observance of cost effectiveness, transparency and accountability. Improvement of system of grievances and feedback mechanism. Rationalization of the support system to ensure wider coverage and effective impact of operations and administration. Promotion of unity, team work and camaraderie in all mission performances of PCG units. Good working relationship with partner agencies, nations, and industry associations.
