18650 Battery,2 Packs 3.7V 18650 Button Top Battery 18650 Rechargeable Batteries for Headlamp, LED Flashlight, Electronic Devices etc (Yellow)

Holds charge. Lasts days. Charge times as expected.

as the owner of probably about three dozen solar spotlights, walk lights, and post lights, I like to have backups for the inevitable moment when the current batteries cycle out and can no longer take a charge from the sun. These rechargeable batteries charged properly and fairly quickly and now give me the comfort of knowing I have at least two popular 18650 rechargeable batteries ready to be put in service when the time comes. I like that.

Working perfectly …

I've been using 1800mAh batteries for my flashlight and can't say that I've noticed any difference so far with these, but they work great. My lights are super bright and these provide plenty of power and recharge quickly. Very pleased with this set of two that includes a plastic case for storage.
