18650 Rechargeable Battery 3.7V High Capacity 3500mAh Genuine18650 Flat Top Flashlight Battery for Headlamp, LED Flashlight

Delivered as promised, very well packaged. Using these in a portable amateur radio project and they are of good quality and provide battery life on a charge better than I expected. These are the flat top version and fit well. Good value and functionality is excellent.

Great batteries. They hold a charge well and they come with a little case. Everything I needed

Batteries were great

One works like a charm, the other though, it dies completely once it hits 1/4 battery life. Fairly inconvenient.

I purchased these to replace the 18650s in my rechargeable e cig, they are the perfect size and seem to do the job properly. I have been using them for about ,30 days and they are still going strong. Ill update in a few weeks.

Could not get one to charge in my Charger, other one charged up completely but does not produce that much power to use in my vape. After like an hour of use the power level was dropping fast. Not very satisfied. Only thing i like about this was i thought i was buying 1 battery and ended up with 2. Sucks it does not work well

used to repair a Greenworks 80v battery pack.

These are buttonless batteries. This works for me, just be aware.
