Compatible Motorola R7 Radio Battery

This lithium-ion pack replaces the original Motorola PMNN series batteries used in R7 and R7A two-way radios. It fits marine and professional users who need a direct replacement for part numbers PMNN4407, PMNN4407A, PMNN4807, PMNN4807A, PMNN4808, PMNN4808A, PMNN4809, PMNN4809A, PMNN4810 and PMNN4810A. The black housing matches the original equipment appearance.

7.4 V 2.25 Ah Capacity Rating

The single specification that decides fit is the 7.4 volt 2.25 ampere-hour rating, which delivers 16.65 watt-hours of energy. This matches the IMPRES capacity spec of the OEM cells so the radio’s fuel gauge and charge management operate correctly. Buyers who need a higher capacity pack for longer shifts cannot use this model.

Steady Output During Extended Transmit

Under sustained load the lithium-ion chemistry maintains a stable voltage through long transmit cycles rather than sagging after a short burst. The 2250 mAh rating supports repeated push-to-talk use across a full duty shift. Users who require hot-swap capability or multi-bay charging stations should verify those features separately as they are not described here.

Questions about this item

How long will the 2.25 Ah capacity actually run my Motorola R7?

The 2.25 Ah rating at 7.4 V delivers 16.65 Wh, giving typical mixed-duty use of a full shift on the R7 or R7A before recharge.

Does the IMPRES designation change how the battery communicates with the radio?

IMPRES enables the radio to read the battery’s 7.4 V 2250 mAh data and optimise charge cycles, but the pack still connects through the standard Motorola R7 battery rails.

Will the 120.50 x 54.80 x 34.40 mm case fit the R7 battery compartment without modification?

Yes, the dimensions match the OEM PMNN4807/PMNN4809/PMNN4810 form factor, so the pack slides into the R7 and R7A latch without filing or shims.
