Product information

Description

The ROCKET HR3-850-R2U is a rechargeable AAA battery based on Nickel-Metal Hydride (NiMH) technology. Supplied in blister packaging, this 1.2 V battery comes as a set of four and is designed for repeated use in a variety of household devices.

How to use

Install the batteries into the device matching the polarity markings. These ROCKET NiMH AAA cells are supplied precharged and can be used immediately.
