Compatible Battery for Motorola APX and XPR Series

This lithium-ion battery replaces original packs for Motorola APX 2000, APX 3000, APX 4000 and XPR 3300, 3500, 7350, 7380, 7550 and 7580 radios. It matches part numbers NNTN8128A, NNTN8129AR, PMNN4406AR, PMNN4406BR, PMNN4424 and PMNN4424A. The unit is brand new and fully OEM compatible.

Sustained Operation on a 2.3 Ah Pack

Rated at 7.4 V and 2300 mAh, the cell delivers 17.02 Wh for extended shift coverage. Lithium-ion chemistry maintains a stable voltage curve through the discharge cycle, so transmit power stays consistent from start to finish. No memory effect means the pack can be topped up between calls without capacity loss.

Thermals, Noise and Power Draw in Normal Use

The sealed enclosure has no moving parts, so operation is silent. Typical internal resistance keeps heat rise low during standard duty cycles. Charging follows standard lithium-ion profiles at 7.4 V, drawing only the current the pack accepts. The black housing measures 118.70 x 55.00 x 40.30 mm.

Questions about this item

Does the 7.4 V 2300 mAh Li-ion pack generate noticeable heat during a full shift?

Li-ion chemistry runs cooler than older Ni-MH packs; the 17.02 Wh rating keeps temperature rise low even under continuous transmit cycles.

What radio models must I already own for this battery to fit?

It fits Motorola APX 2000, 3000, 4000 series and MOTOTRBO XPR 3300, 3500, 7350, 7380, 7550, 7580 that use part numbers NNTN8128A, NNTN8129AR, PMNN4406AR, PMNN4406BR, PMNN4424 or PMNN4424AImpres.

Will the 118.70 × 55.00 × 40.30 mm case sit properly in my existing APX 3000 charger?

Yes — the dimensions match the OEM NNTN8129AR form factor, so the battery seats and charges in the same single-slot or multi-unit chargers you already use.
