Batteries sold individually.

The advantage of this cell is that it features a button top making it particularly compatible with many flashlight applications.

Rechargeable Lithium batteries are rapidly becoming a very economical way to lower the operating costs of Lithium-Powered flashlights. We offer a number of different options in order to meet any rechargeable needs.

These are Protected batteries. These fully protected cells simplify usage with their integrated PCB. a pair of these cells is about the same size as 3 CR123A batteries and can be used as a rechargeable substitute in some lights which use 3 CR123A batteries. These cells are not for pack building as doing so may defeat or damage the PCB protection which is matched to the correct voltage on a single cell - nor can these cells be welded or soldered upon. If you are building a pack please choose one of our other cells and the appropriate PCB.
