18650 Battery for 2 Pack 3.7 Volt 18650 Rechargeable Battery 3000mAh Flat Top Battery for Headlamp,LED Flashlight,Mini Fans etc

Works well.

The physical size of this battery is about 5 mm shorter than the one I was replacing. Could not use them

Not really much to say about a battery. It works as expected and I put it in my solar patio lights and it worked just fine.

Not sure it is my imagination but they seem to make my flashlight brighter than the original battery.they do have better Mah. Will buy again when needed!

These typical 18650 batteries are the perfect set for an old headlamp I have that has worn out batteries that don’t last long anymore.Fully charged they are reading 4.16 Volts and their rated 3000mAh is on par with most typical 18650 cells. Some similar sized cells are advertised to have roughly three times the mAh capacity that these have, which I believe is unrealistic and exaggerated to boost sales, so it’s great to see these cells advertised with what is most likely an honest attainable capacity.The label designates these batteries as INR type chemistry, which makes them more stable with a lesser chance of thermal runaway. They are ideally suited for portable lighting applications like my headlamp.They look to be assembled with care with clean lettering and the purple shrink wrap tight and straight. Logically, I will not know if they will keep the headlamp operating for as long as I expect until I have run them for a number of cycles, but with their clean appearance, honest rating, and reasonable price, I anticipate good results. If I find differently, I will update my review accordingly.

Batteries work with Vape Rigs but drain very quickly. Worth it for the price

These batteries charge quickly and work great in my flashlight. No complaints!

batteries do not put off amp cheap
