Unprotected CR2 300 mAh rechargeable battery - includes a magnetic spacer so that the battery will fit the Nano and DSD chargers<

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 unprotected batteries.

We recommend unprotected batteries for all applications that can use a 3.6-4.2 volt battery. The cells on this page are unprotected Lithium R123 Cells that charge up to 4.2 volts with nominal 3.6 output. Do not over-discharge, as this will ruin the battery. We cannot replace batteries that have been over-discharged. Over-discharge is rarely a problem with these batteries, as incandescent flashlights will shut off and stop drawing current, and most LED flashlights will begin blinking rapidly.
