I installed these in my pocket radiomaster radio. They worked great and hold their charge for a very long time. Also easy to charge them through my radio too.

With a 9900 mAh rating I expected these batteries to be more than enough for a small LED flashlight. This was not the case. After charging and using them several times I found the longest each battery would last is about 5 minuets. Don’t waste your time and money with these.I would send them back if I could but by the time I was able to test them out several times with a full 2 hour charge in between my return period was over. Now to the trash they will go.

Comes with two batteries and a single battery charger which I wasn’t expecting. Worth the price so far.

These show on the label 9900mah however they do not last on full charge as long as the 2200mah batteries that came with my headlamp. They can print anything they want on the label but these are not what they say they are. Very disappointed in Amazon for selling a falsely labeled product.I and my crew use head lamps in construction everyday. These do not last through the day off a full charge.

This set of batteries will not fit into my e-cigarette. It is slightly bigger than the batteries with lower milliamps. Not worth the hassle of returning. Don’t get these if you have a tight fit already.
