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

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

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

Good price,lotta juice

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.

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

Charged and put in flashlight it’s a bright as new. These flashlights take a long time to run the battery down. Old batteries were only recharged twice in 6 years. Hoping the replacements do as well.

They seem to work

These come in handy for things you use a lot just swap out batteries and recharge
