18650 Rechargeable Battery 9900mAh 3.7v Li-ion Batteries for Handheld Flashlights, Headlamps, Doorbells, Toys, Cameras (2pcs, Button Top)

Very good batteries at a good price

My light is so much brighter.Works great in light box and charging box.

The battery performed exactly as advertised, holding its charge well since purchase. It charges efficiently and has maintained consistent performance throughout use. No issues with capacity degradation noted so far, making it a reliable power source for its intended application.

The batteries did not come fully charged. Once I charged them, the batteries worked fine.

Here is the deal with these, based on the length these last and saying that the storage is bigger then most is a joke. I had a pair of different ones (I'll be nice and not advertise them here) and their capacity was started much lower then these and they lasted days longer. I'm not sure these claim to be more and not or all 4 I got are trash but I will not buy these ever again.Value for money, again, either they are saying larger capacity and isn't or they all just don't hold a charge and are terrible.Keep in mind, saving money and their claim of larger capacity doesn't always me better or even worth it. I would spend double for batteries that claim this capacity and actually provide it.Do not buy, spend the extra money on a reliable brand.

Muy buen producto para mis audífonos, la linterna y los juguetes de mis nietos.

Good batteries (so far) at a great price. Hold a charge well and last longer than some other brands I have purchased.

I have 2 vape units and alternate between the two, so I am not impressed.
