4 Pack Rechargeable Battery 14500 3.7V 800mAh Li-ion, Rechargeable Batteries for Flashlight, Toys etc.

Perfect

Ordered 8 800 mah batteries. All the batteries tested over 800 mah. Its great to find a good battery where the manufacturer doesn’t overrated them. There are so many junk batteries out there.

I really like these cells. I purchased them for several AA 3.7v capable flashlights I have. They have been working perfectly and I won't hesitate to buy them again.

Came fully charged so we'll see how long they last.

These batteries are almost perfect! Their run time in my Olight Diffuser is on par with the factory battery (only 15 minutes less), strangely it shows a few mAh more though, from my charger. I also use these in 3 other lights I have with no issues.During recharges they've shown no less than 800 mAh which is great!I have another set of these and the plastic casing is peeling or scratching off easily, hopefully these won’t have that issue.There doesn't seem to be a lot of 14500 options and these do perform great.

I really appreciate when a company is honest and exceeds what they say their product will do. I used my Tenergy diagnostic battery analyser that charges and does a load test. My four Jesspow batteries each showed an output of around the range of 830 mAh each. This is about as high as I think a comapny can get out of these tiny 14500 lithium ion batteries. I have a flashlight that uses this size battery and I got tired of using another brand of battery that only put out about 80. Therefore I rate this Jesspow brand as excellent and trustworthy and has earned my five star rating. Thank you Jesspow!

They were all dead batteries

Good capacity and output current. So far a good buy
