3.7 Volt 14500 Rechargeable Battery 2500mAh Battery 4 Pack Large Capacity Batteries for LED Flashlight, Headlamps, Cameras, Doorbells etc

I bought this for a flashlight that I was powering with a standard AA battery although the light was rated for the higher voltage provided by these batteries. The difference in the performance of the light was incredible. I bought the batteries and charger for economical reasons and both performed well. The batteries don't last long on a charge but as i only need one at a time and I have 2 freshly charged at all times it worked out well for my situation.

Perfect

I purchased this set specifically for a preferred flashlight. It gets used quite often and having fully charged batteries on hand means uninterrupted use. I have another set for other devices and it continues to serve me well. This set is economical and versatile. The batteries fit perfectly and provide sufficient power for a brighter beam.

In testing these batteries in real life application, They produce the Voltage of 3.7. However, Based on the time to charge with a 1 Watt Solar panel and looking at discharge, these are not 2500mAh capacity batteries. Again, they work. But, not the capacity that I was expecting.

These work fine. They charged up quickly and I use them in some smaller flashlights and outside garden lights with 14500 batteries.

Did not come with the cable to the charger ,

In this four pack of batteries one is dead, one holds a good charge, and the other two are somewhere in-between. All four have only been used in the same led flashlight and have uneven battery life.

Good 3.7V lithium batteries.
