VTCBATT AAA800 1.2V/3.6V 800mAh Ni-MH Battery Specification
The AAA800 series is a rechargeable Nickel-Metal Hydride battery platform for compact AAA cell devices and custom stack-up battery packs. It supports 1.2V single-cell use and 3.6V pack assembly using three AAA cells.
Product Overview
The AAA800 cell is rated at 1.2V nominal voltage and 800mAh nominal capacity. For equipment that needs a wired rechargeable battery, the cells can be stacked into a 3.6V AAA800mAh pack with heat-shrink wrapping, lead wires, and a connector matched to the customer’s device.
Core Electrical Parameters
