Fenix ARB-L14U AA 1600mAh 1.5V Lithium Ion (Li-ion) Button Top Battery with Micro USB Charging Port - Clam Shell

I bought this for my JetBeam PA12. The capacity is impressive compared to other 14500’s and it runs it brighter than a standard AA.

holds charge well
very easy to recharge use cellphone cable excellent

I have a LED "firefly" light that runs on one AA. An Enloop at full charge is below the threashold. An alkaline was giving me 10 or 11 eleven nights (it has a light sensor) in June. These would give me 5 nights. With a longer nights it is between 3 and 4 nights. They charge easily and 5 months of use have certianly paid for themselfs.

It does a great job in the flashlights I have that it does work in. But just make sure if you buy it that your flashlights take protected cells otherwise it most likely wont work. But I am very happy with my purchase and will buy more if needed.

They are much much better than the old rechargeable batteries I had. They are a full 1.5 volt and they do not self drain like my old batteries did. I have been using them for several months now and I am planning on purchasing more of them. I was going to order a lot more however after reading one of the other reviews saying they do not work well in am radios. I may only purchase 4 or 8 more. I have been using them in controllers, computer mouse as well as in several other devices and I have been very happy with them. My only fear now is the kid grabbing the 3.7 volt 14500 batteries and sticking them in the Wii remotes and frying them. Other wise they seem to work very well in everything I have tried them in. when i order more of them eventually I will try them in an 11 meter am radio and see if they work or not before purchasing even more of them. I have been very happy with them so far and I would recommend them for most AA battery uses. Read LessRead less about I purchased 2 of these batteries when
