Why Professionals Choose the Motorola Battery PMNN4476A
The CP185 and CP100D are workhorse portables used in commercial cleaning, facilities maintenance, hospitality, and light manufacturing - environments where a radio runs from first shift to last without going back to a charger. A battery that drops below 8 hours under moderate use forces mid-shift swaps, which means spare batteries, chargers at every station, and staff who track battery rotation. The PMNN4476A is rated for up to 11 hours under heavy usage - enough to cover a double shift without a swap on a standard 5-5-90 duty cycle.
At 1750 mAh and 7.4V, the PMNN4476A matches the capacity of the battery shipped with the CP185 from the factory. The IP54 rating protects against dust ingress and water spray from any direction - relevant for housekeeping, food service, and outdoor maintenance crews where the radio is regularly exposed to moisture and particulate. The battery is the current production successor to the PMNN4081AR and PMNN4081BR, sharing the same form factor and connector - no modification required on existing charging infrastructure (WPLN4137, BC-PMPN4174) or holsters.
Third-party 1750 mAh batteries for the CP185 are widely available, but cell quality and IP54 seal integrity vary significantly across manufacturers. The PMNN4476A is manufactured to Motorola's OEM specification, tested against the CP185 platform, and backed by a 48-month workmanship warranty - substantially longer than the 1-year coverage typical of aftermarket cells.
