Motorola PMNN4890A IMPRES™ 3200 mAh Li-Ion High-Capacity Battery (IP67, TIA4950)
Intrinsically Safe IMPRES™ high-capacity power solution for Motorola R5 and R5a series radios.
The Motorola PMNN4890A is a premium, high-capacity Lithium-Ion battery engineered specifically for the Motorola R5 and R5a series digital portable radios. As the updated successor to the PMNN4890, this 3200 mAh battery is built to sustain long-duration shifts in the most demanding mission-critical environments. Its IP67 rating ensures full operation after total immersion in water up to 1 meter for 30 minutes, making it the definitive choice for fire services, heavy industrial sites, and maritime security.
Equipped with Motorola's proprietary IMPRES™ technology, the PMNN4890A communicates directly with IMPRES chargers to automate battery maintenance, track usage patterns, and perform adaptive reconditioning only when necessary — significantly extending cycle life and ensuring full rated capacity on every charge. The integrated TIA4950 certification designates this battery as Intrinsically Safe, allowing use in hazardous locations where flammable gases, vapors, or combustible dust may be present.

Frequently Asked Questions
Is the PMNN4890A backward compatible with the R7 series?
While the R5 and R7 share similar design language, you should always verify the specific TIA4950 safety pairing in your radio's manual before swapping batteries between different series. Contact Atlantic Radio to confirm compatibility for your specific deployment.
How often does the PMNN4890A need reconditioning?
With IMPRES™ technology, the charger determines the reconditioning schedule based on actual usage patterns. There is no need for manual deep-cycling — the IMPRES system handles it automatically.
Can I use a non-IMPRES charger with the PMNN4890A?
Yes, but you will lose the automated maintenance features and extended warranty benefits associated with the IMPRES ecosystem. For maximum battery lifespan and accurate charge data, an IMPRES charger is strongly recommended.
