Question: Any idea how many recharges the battery can sustain or how long it can sit before discharging if fully charged?  Replacement battery available?
Document: The ambient weather radio is a great buy. I am impressed with the reception the radio has for all three modes especially the weather. I was also surprised to find out how long the battery lasted after being fully charged. The solar charger and hand crank charger are convenient when no power is available. The audio input is a nice feature to have if you don't want to listen to the radio or can't get any stations.
When I first received it I was pleased, and all seemed to be as advertised. I fully charged it via usb and took it camping with me and it made it the first night before crapping out on me. It would turn on but then flash a battery light and shut itself off after about 30 seconds of use. Now I hope its just the battery and will have to order a replacement but overall i was not impressed with the one day use i got out of it.
Pressing the reset button doesn't help. So what the heck happened? She's now on a trek up the mountains near Mt. Everest. Fortunately she was able to get her phone fully charged before heading up the trail, but is now conserving her battery for pictures and video; and a few texts home (yes, the area around Everest has cell service everywhere).When she returns, I'll have her send this thing back for a refund. Not replacement; refund.
I love this little radio. It has so many options for keeping it charged that that should never be a problem. The maker's web site also has the replacement battery for it if you ever need one. I'm sure that any other RCR-123 rechargeable of at least the 800mah capacity would also work though. The only thing I kind of wish it had is a headphone jack but since I really don't like being tethered to my electronics like that, it's a minor issue.
It won't charge half the time, and then when it does say it charged and is supposedly &#34;fully charged&#34; I'll sit it aside and a couple days later it is dead (not in NOAA scan mode) just sitting there doing nothing. I would not rely on this radio for anything.
I'm told to do this every couple of weeks.It did take many hours to do that, so maybe the battery was never fully charged. So far it has ran without any issues for a couple of days.If I do not have anymore issues and this does the trick, which it seems to, then I will update the review again. I really do like this unit.
I was initially impressed with this unit. It's fairly rugged, very compact and appeared to work well. I fully charged it the first time I used it. Then I used it for a while. Then I let it sit for a couple months because it is an emergency radio after all, and it should be able to sit. When we were expecting some bad weather, I took it out of storage and it didn't work at all. I tried cranking it until I was blue in the face and nothing.
Packed in the original box and ready to go. Even the battery was fully charged. Some on in China must like pop dance music because it was tuned to 94.5FM. It's simple to operate, well built and works perfectly.The light is bright, the antenna is just long enough and not flimsy. Rounded corners with an easy to grip feel. Nothing to hate about this one.Pros: Well built and direction free use.
The ambient weather WR-111B is perfect for emergencies. It uses solar light, a hand crank, and a USB outlet for energy. It also includes separate plugs that connect to various heads which will adapt to charge multiple electronics. I have already used the hand crank to charge my iphone and my ipod! This machine also comes with one fully charged lithium battery. Although these batteries have a long life span I plan to purchase an extra battery as a back-up.
This is a compact unit which is easy to use and has very good reception. After reviewing several products the deciding factor in choosing Ambient Weather, was the ability to use a readily available rechargeable replacement battery, if the need should ever arise. A great product design at a reasonable cost. I just hope that I never have to use it in an emergency situation.
Answer: Great Questions.  I have had mine for almost a year.  I use it several times a week and it is great.  It charges in little sunlight.  I experienced discharge of battery and replaced the battery after a year ( keeping in mind I used it on a daily basis but I let it sit for about 4 months).  My suggestion is to remove the battery for long term storage or when you need to use it or only putting battery in once every month to recharge if needed.  I have found it very useful when camping, in the office, and in power outages for getting emergency alerts when the power goes out.  From my understanding you should be able to find a replacement battery (only one needed) on amazon for around $10 (Ambient Weather WR-BATT 3.7V / 800 mAh Rechargeable Battery (LIR123A)) .  One of the reasons I chose this unit is because the rechargeable battery could be changed. Allot of these rechargeable type units the battery can not be changed.  But overall the reception is good, all the charging options are included with the unit, the unit recharges small electronics, and it is compact and lightweight.  The volume is not overly loud, some may want a louder unit but i think it is loud enough.  I would recommend this unit if you are looking at alternatives like this one for a reasonable price.
