7.2V 2400mAh Ni-MH Replacement Battery 2-Pack - Long Run Time

In this review the focus is on a practical replacement power option for legacy Motorola handhelds. The 2-pack of 7.2V 2400mAh Ni-MH batteries is aimed at radio users who need longer runtime without upgrading equipment; the single biggest reason to buy is the higher 2400mAh capacity that extends shift length compared with many older OEM packs. The reviewer tested fit, basic charge behavior, and day-to-day handling to judge whether this inexpensive two-pack is a sensible swap for users running CP110, RDU2020 and similar models.

Key Features

• High capacity: The 2400mAh Ni-MH cells deliver noticeably longer runtime for long shifts or field work compared with lower-capacity replacements.
• Wide compatibility: Designed to replace common battery part numbers like PMNN6035, RLN6305B and RLN6308B so it fits several Motorola CP and RDU series radios.
• Durable design: Built-in short-circuit and overcharge protection helps preserve battery life and provides safer daily operation.
• Portable kit: Each battery ships with a belt clip for easier carry during rounds or when hands-on mobility is needed.
• Two-pack value: Including two identical batteries lets users rotate packs and reduces downtime while one charges.

Who It's For

This replacement battery set is best for two-way radio users who operate older Motorola CP110, CP1180, RDU2020, RDU4160, RDV2080D and RDV5100 radios and want extended runtime without replacing equipment. Security teams, facility maintenance crews, and event staff who need affordable spare packs will appreciate the 2-pack configuration and included belt clips.

Users who require specialized charging systems should note a compatibility caveat: these packs are not compatible with RLN6175A chargers, so anyone using that specific dock should look for a battery confirmed for that charger instead.
