18650 Battery 3.7 Volt 2 Packs 18650 Button Top Battery 3400mAh 18650 Rechargeable Batteries 18650 for Flashlights, Headlamps, Doorbells, RC Cars

Work great. I used these for some magnetic lights purchased from Harbor Freight. Popped them in and they charged right up. Saved me a ton over replacing lights.

I use these in my Radiomaster Boxer radio. Easy to charge and they last a long time as expected.

I bought these for a Meshtastic board power supply. The batteries work very well and do the job but they do not in my opinion have the 3000 mah rating they claim. When I run them down to near zero and put them in my high quality charger, it will accept about 1500 mah of charge to bring them up to 100%. Maybe after a few more cycles they will improve as they are new. I will edit my review if I find a change with time.

Perfect replacement batteries for theflashlights my wife bought on Amazon.Good value.

It works and can recharge

These better is only lasted 20 minutes in my digital night vision monocular, but it comes with a free charger so…

x̌ 18650 batteries.Note these are button top batteries and one should check the type of battery the device requires button top batteries or they may not fit your device

Put these batteries in a flashlight; the light flashed on for a second, batteries started smoking. Obviously not sending these back in the mail so it looks like we’re out of luck! To clarify, I verified correct battery number for the flashlight so this definitely is a product issue.
