Product Info for Ultrafire Protected Rechargeable Lithium Battery

The Ultrafire Protected Rechargeable Lithium Battery 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. These fully protected cells simplify usage with their integrated PCB. Perfect for your single cell application, the Ultrafire Rechargeable Batteries are not for pack building as doing so will defeat the PCB protection which is matched to the correct voltage on a single cell.
