18650 Rechargeable Battery 3.7V 9900mah High Capacity Long-Lasting for Flashlight, Toys and Pathlight 250115-3S (Flat Top, 2 Pack)

I will never run out of power with this set, lol. I have a couple of overhead camping lights that take two of these and between the mah's and the set, I will not be in the dark if I don't want to be :)

This battery is a little bit difficult to find in the stores. Glad I found it here at a decent price.

Works as marketed, charges fast,

I thought that these would last a full 8 hour shift as the 2700Ah batteries last for about 4 hours. These being 3.6 times the power would last 10 hours. Nope, just 5 hours. So I am a little concerned that the rating on these isn't correct. The cheap price still makes these a good buy tho.

I get nearly 7 hours of use in my camera with 3200 mAh batteries and with these 9900s not even 5 hours. Would not recommend them.

Batteries are really light weight, like dollar store batteries are. I think the 9900maAh claim is sketchy.

I have other 18650 batteries and they last longer than these do. Tested the batteries and one battery went dead and cannot be charged again. They say there is a high low protection circuit on the batteries but that doesn't seem to work.

Claims to be a 9900mah… my other 3300mah lasts twice as long. If they held a charge longer I would be happy… in all actuality, they just left me in the dark.
