18650 Rechargeable Battery 3.7 Volt Rechargeable Battery Button Top Li Batteries for Flashlights, Headlamps 2 Pack

Charger works great, can do 4 at a time

Good price,lotta juice

Batteries work as advertised. Produces a very bright and reliable light source.

I fell for the good reviews and thought I was buying a quality battery set different from the others being sold here. However, as the packaging is the same as the others, these batteries also perform as poorly. I needed replacements for a high power 500 lumen Xenon flashlight that used to pour out bright & intense light down the block, but these batteries, when taken straight out of my charger, only produces a weak & pathetic yellow glow. A recharge resulted in the same weak performance. These batteries are as weak as all the other weak green batteries sold here. Don't Bother.

The batteries did not come fully charged. Once I charged them, the batteries worked fine.

Excellent 18650s! These work great in my flashlights! They last a long time before recharging and the output is excellent. Will buy more.

Great

Have to use them longer to give a good review,will give up date later .
