### device:

Battery charger
* Many battery chargers give only a fraction of rated charge amperes when used with a generator.
* Some battery chargers use the battery itself to help control the voltage spikes.
* are located in garages.
* can overheat, presenting fire and burn hazards.

### device | battery:

Acid battery
* Acid batteries contain acid electrolytes
* Most acid batteries contain acid electrolytes

Aggravated battery
* involves the intent to injure and the actual infliction of bodily harm.
* is knowingly committed on a correctional officer engaged in official duties.
* means multiple gunshots or a particularly violent killing.

Battery life
* affects how much and the quality of data received from a tag.
* depends on the size of the iguana's toe nails.
* is about one day's worth of continuous use
  - always a major flaw in cellular phones
* is dependent on cycle
  - many conditions
* is determined by the amount of data transmitted
  - number of times it is recharged
  - extended by decreasing the degree to which the batteries are discharged
  - important for digital cameras

Flashlight battery
* Flashlight batteries are part of flashlights.
* Most flashlight batteries are part of flashlights.

Lead battery
* All lead batteries work on the same set of reactions and use the same active materials.
* Lead batteries constitute the most dependable way to store energy for future use.

Nicad battery
* NiCad batteries are the most widely used type of rechargeable battery
  - outperform alkaline in sub freezing temperatures
* Nicad batteries are a pain, but they do recycle a flash quickly
  - develop a memory based on their usage history
  - require special care and feeding

### device | battery:

Rechargeable battery
* Most rechargeable batteries lose charge.
* Most rechargeable batteries provide output voltage
* Rechargeable batteries are a convenience available on higher-end devices
  - type of reusable general purpose battery
  - cheap and long-lasting
  - famous for having problems
  - good in that they can be charged hundreds of times
  - made with cadmium and nickel
  - the largest source of cadmium in the municipal waste stream
  - very heavy and take a long time to charge
* Rechargeable batteries come in many shapes sizes and chemical groups
  - varieties and they all eventually die
  - contain heavy metals and generally weigh more than double layer capacitors
* Rechargeable batteries have a lower capacity than disposable alkaline batteries
  - less capacity than primary cells as shown in the following chart
  - hold energy and, when triggered, release stored energy to the flash tube
* Rechargeable batteries lose capacity unless they are constantly trickle-charged
  - make much more environmental and economic sense than single-use batteries
* Rechargeable batteries provide functions
  - require external and often costly charging devices
  - tend to discharge themselves much faster than non-rechargeables
* activates lights when power goes out.

Storage battery
* Storage batteries Accumulate up trophic levels.
* Storage batteries are the heart of an independent power system
  - principal source of standby power for crossing warning systems
  - provide the energy required to start the engine

Vehicle battery
* All vehicle batteries contain sulfuric acid and produce hydrogen and oxygen gases.
* Vehicle batteries produce highly-combustible gases, which, if ignited, can cause explosions.
