Motorola PMNN4434 Spare Replacement Battery RM Series

The PMNN4434 is the standard Li-Ion pack for Motorola's RM Series, and it is the battery an RM radio ships with rather than an upgrade. Motorola's RM Series package contents list a 2100 mAh Li-Ion battery alongside the radio, the carry holster and the drop-in charger.

Buying a spare is usually about shift length rather than failure. A second pack charging while the first is worn is what keeps a radio on the floor across a double shift without anyone waiting on a charger.

It fits the RM Series portables: RMU2080D, RMU2080, RMV2080, RMU2040, RMM2050 and RMU2043. Motorola also lists a high capacity pack, the PMNN4453, for sites that want longer runtime from the same radio.

⚠️ Match the part number and the radio series before ordering so the contacts, the case and the charger all agree. Call CMI at (310) 753-0991 and we will confirm the pack against your radios.
