Replacement radio battery

The BatteryJack inc. pack replaces Motorola OEM part numbers PMNN4080 through PMNN4476A and fits radios such as the CP1300, CP1600, CP1660, CP476 and P165. It is built for professional two-way radio users who need a reliable lithium-ion power source.

Thermals noise and power

The 7.4V 2600mAh lithium-ion chemistry delivers steady voltage for extended talk time without the memory effect of older packs. Normal operation stays cool and silent because the cell has no moving parts.

Build fit and clearance

Each pack slides into the radio battery compartment and locks with the original latch, so no adapter or modification is required. The two-pack bundle keeps one unit charging while the other powers the radio, freeing the user from downtime during shifts.

Questions about this item

How do I install the PMNN4082AR battery in a Motorola CP476 radio, and what step is often missed?

Slide the pack into the radio battery rail until the latch clicks; the step often missed is ensuring the contact pins align fully before locking the latch.

What replacement will the PMNN4081 battery need later, and when?

Replace the lithium‑ion pack when runtime falls noticeably below the original 2600 mAh capacity; no other user‑serviceable parts are inside.

What limit appears first during extended transmit sessions with this 7.4 V battery?

The pack’s thermal protection will trigger before the 2600 mAh capacity is fully depleted during continuous high‑power transmission.
