Direct replacement for Motorola R7 two-way radios

This Cameron Sino battery replaces the original PMNN4407 and PMNN4407A cells used in Motorola R7 two-way radios. It delivers the same 2250mAh capacity and 16.65Wh energy rating at 7.4 volts. The lithium-ion pack uses a fully decoded chip so the radio recognises it immediately. It is a new unit supplied with protective foam packaging.

Sustained shift use with built-in protection

Under continuous transmit and receive cycles the battery maintains stable voltage output without sudden drops. Integrated safeguards prevent overcharge, over-discharge, over-voltage and short-circuit conditions during long shifts. The chemistry reaches its best runtime after two or three full charge and discharge cycles. ISO9001, RoHS and CE certifications confirm consistent manufacturing quality.

2250mAh capacity at 7.4 volts for compatible models

The single figure that decides fit is the 2250mAh capacity at 7.4 volts matching the original PMNN4407 specification. Buyers whose radios require a different voltage or a higher capacity will not be served by this pack. Verify the part number on your existing battery against the listed compatibles before ordering.

Questions about this item

How much heat does the 7.4 V lithium-ion pack generate during continuous radio use?

The battery operates at a nominal 7.4 volts and 2250 mAh; normal warmth is expected during extended transmit cycles, but the built-in protection circuit prevents overheating.

What must I already own to install this replacement pack in my Motorola R7?

You need the Motorola R7 two-way radio itself and a compatible charger that supports the original PMNN4407 or PMNN4407A part numbers.

Will this 2250 mAh cell work alongside my older Motorola PMNN4807 spare batteries?

Yes, it shares the same 7.4 V chemistry and form factor as the PMNN4807, PMNN4808, PMNN4809 and PMNN4810 series, so they can be rotated in the same radio and charger.
