IMPRES™ 3200mAh Li-Ion High-Capacity Battery (IP67 Rated)

Intrinsically Safe TIA4950 Power Solution for Motorola R5 Series Radios

The Motorola PMNN4890A is a premium, high-capacity energy solution engineered specifically for the Motorola R5 and R5a series of digital portable radios. As the updated successor to the PMNN4890, this 3200mAh Lithium-Ion battery is built to sustain long-duration shifts in the most demanding mission-critical environments. It features an IP67 rating, ensuring the battery remains fully operational even 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. The Motorola PMNN4890A is the updated version of the Motorola PMNN4890.

Equipped with Motorola’s proprietary IMPRES™ technology, the PMNN4890A communicates directly with IMPRES chargers to automate battery maintenance. This "smart" system tracks usage patterns to perform adaptive reconditioning only when necessary, significantly extending the battery's overall cycle life and ensuring it reaches its full rated capacity every time it leaves the charger. Furthermore, the integrated TIA4950 certification designates this battery as Intrinsically Safe, allowing it to be used in hazardous locations where flammable gases, vapors, or combustible dust may be present.

Safety and longevity are prioritized through advanced over-discharge protection, which prevents the internal cells from reaching critically low voltage levels that could cause permanent chemical damage. Whether you are managing a large-scale emergency response or a 24-hour industrial facility, the Motorola PMNN4890A provides the "Operations Critical" reliability and safety certifications required to keep your team connected without interruption.

Frequently Asked Questions

• Is this battery 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.
• How often does it need reconditioning? With IMPRES technology, the charger determines the schedule based on actual usage; there is no need for manual deep-cycling.
• Can I use a non-IMPRES charger? You can, but you will lose the automated maintenance features and the extended warranty benefits associated with the IMPRES ecosystem.
