18650 Rechargeable Battery 9900mAh Lithium ion 3.7Volt Large Capacity Batteries for Headlamp Flashlight (Button Top, 2 Pack)

Great batteries at a great price. I have used them for years and they last just as long as the name brand.

I've been using these batteries in a s&w rechargeable flashlight and they are even better than the original battery. Charges efficient and lasts longer than before. Great fit for high lumen power consumption flashlights.

They came ready to use

Great for my flashlight that uses these batteries. Long lasting in use

These batteries do not have a 8800 mAh, real world ability to hold a charge for that long. They may have a 3000 mAh ability. I compared the power drain on these and a 6000 mAh rated battery from another manufacturer, and these batteries drained down at about two times as fast in percent of charge than the 6000 battery.

Bought these to use in a handheld portable fan that we took to a music festival. Both batteries arrived charged, and allowed us to run the fan on and off for about 1hr (pretty much constantly) on each battery. Was able to still use the fan while plugged into a charger, and got another full hour or so out of one battery after about ~15 mins charging time with a portable charger.

Not what they say they are. Another China Repoff. Don't waste you money. Buy a local brand name.

Got these for my coast headlight. The AAA batteries just don't last very long. I use my headlight daily, and it is on at least 50% of the time so I went through AAA batteries very quickly. These have solved the problem.
