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.

verified testing on minimum 2 test cycles on two different engineering tester/chargers never cycled over 13 to 14 hundred mAh, Will be returning as misrepresented item, Possibly old batch if these were verified as 3400 by the manufacturer. Information show a possibility of Old stock due to a high internal resistance on first test and under 45 resistance on second cycle test in attempt to balance charge with other 3400 rated batteries sourced last year. batteries tested lower than the 2 I needed to replace in first and second attempts to do a balance charge.

It works and can recharge

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.
