These batteries really make the flashlight shine a lot brighter. The only down side is that you have to have a charger and recharge it before it goes dark which can be rather rapid when the voltage begins to drop. But I do like them.

I ran it for a couple of cycles at 170 mA drain current. The batteries lasted only 5 hours. That is equivalent to 850 mAh capacity. Since the batteries were charged to 4.05Vdc, I would think they should be rated 1000 mAh only. That would be 1/10th of what they claim the capacity was. June 24 update. It's been about 4 months since I purchased 24 of these devices. So far 3 of them failed showing internal shorts.

I love to use rechargeable batteries and these good ones. They seem to last a really long time between charges and my flashlights are considerably brighter using these batteries compared to using the 3 AAA battery cradle that came with my flashlights. I recommend these over others I've tried.

the battery is labeled as a 9900 mah, but so far has the capacity of a 700 mah battery. I was really hoping that this wasn't just another cheep battery, but so far it seems to be. If the efficiency improves I will gladly change my review but for now I suggest paying the extra money for a quality battery such as Fenix.

In my order of 4 batteries only two of them worked the others would not even take a charge, internal short? I would think they should have been tested before shipping them out, 50% fail rate is way to high.
