26650 Rechargeable Battery, 2Pcs 3.7V 5000mAh 26650 Lithium 26650 Flat Top Battery for flashlights, Power Tools and Other Equipment

Hold a good charge in an or light for nv scope

Bought these as backups for my flashlights that runs on lithium batteries and they work great.

very strong battery life. id buy again once battery life is gone. i suspect it'll be a long time from now.

Put their battery in...had to toss flashlight out of my hand because it got hot and black smoke coming out. Returning battery. Had to toss both flashlights because we don't take chances. The batteries that were in them...worked...but only held a small charge. That's why I was buying new ones!

Purchase to have as a back up works good

Works as expected

These batts are hard to find locally - I took a chance with ordering these, but can say nothing but good things about them. They power my 500mW laser designator systems great and hold a charge like something I would expect to pay double for.Will buy again!

I’ve bought these batteries for a Dive light that requires 5000 mAh capacity. I have tested these three times on a charge/discharger and Maximum mHh rating that I could get was 4200. Although this is much better than other batteries I have bought on Amazon that were supposed to be rated at 5000 6000 or even 8000, those batteries only had a 2000 mAh capacity, not even close to the sticker.
