    • 1 out of 4 is defective. That's 25%
Size: 1 Count (Pack of 4) Style: 16340 Battery
These batteries seemed like a decent value until I received them and tried charging them up. Out of the 4 pack, 1 is defective and would not charge. A 25% defect rate in a product, is pretty bad. Keep that in mind when making your buying decision.

Size: 1 Count (Pack of 2) Style: 18650 Battery 9900mah
Bought these for my Armytek C2 pro headlamp, which I use for work. Stock battery dims the light after 4-5 hours, these did not hold 2 hours. So, I sent them back.

    • Status indicator doesn’t work
Size: 1 Count (Pack of 2) Style: 14500 USB
Immediately upon opening I figured a charge would be necessary but upon connecting to a verified functioning source I didn’t get a in process light(red) or the full (green) light then I tested them with a voltmeter and they were already within the full range which should have been indicated when connected but there was nothing so I’ll drain on down and see what happens when I know for sure it needs a charge cycle. ... show more

    • Terrible batteries

Definitely not 2800 mah as labeled. More like 400. My fenix 700mah lasts 3 times as long as these.

    • Not 9900 mAh

I think these were designed to fill the gap where real batteries go. Do not buy these. If you read this and you still do, then that's on you.
