Great Battery - Rechargeable - Larger than a AA Battery so it lasts longer between charges
I bought these batteries for my flashlight that uses 3-AA's or 1-3.7v 18650 battery. The 3.7v battery is larger than a AA battery. My flashlight came with a special adapter for this type of battery. I did not even know this type of battery existed until I bought the flashlight and saw that it also could used a 3.7 battery instead of 3 AA's. Anyhow, the 3.7 battery lasts longer in the flashlight the AA's and makes the flashlight brighter. On the plus side this battery is also rechargeable.This battery set included 4 - 3.7v 18650 batteries and a wall charger. I actually have 2 flashlights that take these batteries (1 battery in each}. SO, when the batteries start getting low I just exchange the batteries for the ones that I have charged and charge the ones that are low. Now I always have flashlights that work and have bright lights.

Convenient Setup
I use these batteries in a headlamp while working with our pony out at the ranch at night. The charger is quite handy for a 1 battery or 2 battery charge. I had a 4 battery charger which was cumbersome and charged quite hot. Definitely recommend this battery combo.

Just okay for me.
One battery is DOA, will not hold charge. I was wondering why light was still red after charging overnight and battery was hot. Other batteries remained cool after light turned green. Should have gone with another battery brand.

The batteries turned out to last in a flash light less time than batteries that were rated at 3600mAh (from OUTLITE).I suspect therefor that the rating of 5000mAh of these batteries is incorrect, and is in fact less than the 3600mAh of the OUTLITE batteries.
