IMPRES Lithium-Ion High-Capacity Power Cells for Professional Handheld Fleets
Long-Life Industrial Power Architecture
Equip your mission-critical teams with intelligent, high-capacity power cells engineered to endure long multi-shift rotations.
The genuine Motorola PMNN4544A is an authentic original equipment manufacturer (OEM) high-capacity lithium-ion battery pack engineered specifically for high-tier professional portable transceivers. Featuring original IMPRES smart energy technology, this power cell communicates operational diagnostics directly to matching charging bays to initiate automated reconditioning cycles and maximize overall lifecycle metrics. Integrating the Motorola PMNN4544A into your wireless communication infrastructure provides a reliable energy baseline that prevents sudden equipment power drops during critical site operations. The Motorola PMNN4544A is the updated version of the Motorola PMNN4544.
This ruggedized power cell is built for heavy manufacturing plants, specialized industrial logistics hubs, municipal public works departments, and commercial security operations. The Motorola PMNN4544A features a fully sealed, submersible housing structure certified with an IP68 environmental protection rating, allowing the assembly to survive complete underwater submersion on wet outdoor job sites. Acting as a factory-authorized upgrade, this slim yet high-capacity cell block delivers stable voltage regulation throughout the day without creating excessive weight or altering the ergonomics of the radio frame.
As a modernized power option, the Motorola PMNN4544A serves as the factory-direct replacement for legacy, discontinued battery models such as the PMNN4409. It locks smoothly into the lower hardware rails of compatible transceivers, establishing a clean, debris-resistant physical alignment. Fleet coordinators should note that optimizing the smart reconditioning and automatic maintenance logs requires deploying this battery alongside an approved IMPRES charging station.
Key Features & Benefits
- IMPRES Fleet Intelligence: Automatically communicates battery performance logs, charging history, and cell degradation metrics directly to smart charging docks.
- High-Capacity 2450mAh Runtime: The Motorola PMNN4544A Two-Way Radio Battery for XPR7550e provides extended duty cycles to support uninterrupted field communications across long shifts.
- IP68 Submersible Waterproofing: Fully sealed to repel fine industrial dust, grease accumulation, and total water submersion in challenging outdoor environments.
- Advanced Lithium-Ion Chemistry: Delivers an optimal 18.1 watt-hour energy density in a lightweight profile, avoiding the memory effect issues common to older configurations.
- Genuine Factory Fitment: Eliminates operational downtime caused by loose-fitting third-party power cells by locking perfectly into original hardware rails.

Frequently Asked Questions
Do I need to manually drain this battery to prevent memory effect?
No. The Motorola PMNN4544A utilizes high-grade lithium-ion chemistry combined with automated IMPRES technology, meaning it does not develop a memory effect. You can safely place the battery back into an approved charger at any state of discharge without harming its long-term storage capacity.
Can this high-capacity battery be used with standard non-IMPRES chargers?
Yes, this battery will physically fit into standard non-IMPRES charger pockets and receive a regular electrical charge. However, using a non-smart charger disables all automatic reconditioning tracking, diagnostic communication, and optimized lifecycle management protocols.
Does this replacement power pack carry an intrinsic safety rating for explosive zones?
No. This specific model is a high-durability, IP68 waterproof commercial power cell, but it does not carry a certified UL or HazLoc intrinsic safety rating. It should not be introduced into volatile atmospheres containing combustible vapors or explosive dust layers.
