Replacement Battery for Motorola Radios

This Avantalk PMNN4077C battery replaces original Motorola IMPRES cells used in XPR and XBR series portable radios. It supplies 7.4V and 2300mAh capacity for professional communication users who need a reliable power source. The pack includes a belt clip for secure attachment during field work.

Simple Snap-In Installation

The battery slides into the radio battery compartment and locks with the existing latch; no tools or soldering are required. Alignment tabs match the original housing so the pack seats correctly on the first try. A common issue is forgetting to fully charge the new cell for the initial 2 or 3 cycles before relying on full runtime.

Steady Output During Extended Shifts

Built-in protection circuits guard against over-temperature, over-charge, over-load and short-circuit conditions while the radio transmits continuously. A-class cells and the smart chip maintain stable voltage across long talk cycles rather than sagging after a short burst. IMPRES communication with the charger optimises cycle life over repeated daily use.

Questions about this item

How can I verify the PMNN4077C battery is working correctly after installing it in my XPR6500 radio?

After installation, power on the radio and confirm the battery icon shows a full charge. The IMPRES function will communicate capacity data to the display. A new pack reaches its best performance after two or three complete charge and discharge cycles.

What items are included with the PMNN4077C and what must I purchase separately?

The package includes one PMNN4077C replacement battery and a belt clip. No charger, radio, or additional mounting hardware is supplied; those must be obtained separately if not already owned.

Which compatible model number should I select for my XBR6550 two-way radio?

This single product replaces PMNN4077C, PMNN4077D, PMNN4077E, PMNN4066A and PMNN4069A. All listed part numbers are covered by the same 7.4 V 2300 mAh pack, so no version choice is required.
