Purpose and compatibility

This 1900mAh 7.4V lithium-ion battery powers Motorola CP110 and RDX series two-way radios including RDU2020, RDU2080D, RDV2020, RDU4100, RDU4160D, RDV5100 and similar models. It replaces original equipment numbers RLN6351B, RLN6351C, RLN6308B and RLN6305B for professional communication users.

Voltage and chemistry limits

The 7.4V lithium-ion chemistry delivers the specified capacity only within the radio's designed operating range and charging circuit. Users needing higher voltage or alternative chemistries such as nickel-metal hydride will find this pack electrically incompatible with their equipment.

Capacity determines runtime

The 1900mAh rating sets the practical talk time between charges for supported radios. Operators requiring longer shifts without recharging must select a higher-capacity pack, while those needing lighter weight for occasional use may prefer a lower-capacity alternative.

The 7.4V nominal voltage matches the original equipment specification, so the pack delivers the expected transmit power and receive sensitivity for compatible Motorola two-way radios.

Which battery contacts or connector standard does this pack use?

It is built to fit the Motorola RLN6305 / RLN6305B form factor, making it a direct replacement for RLN6351B, RLN6351C, RLN6308B and RLN6305B packs in the listed radios.
