Rugged Submersible Power Pack for Professional Portable Radios
Equip your handheld two-way radio fleet with a durable, self-calibrating power source engineered to deliver up to 13 hours of continuous performance.
The genuine Motorola PMNN4491E is a professional-grade Motorola PMNN4491E IMPRES Li-ion Battery for XPR 7550e engineered to supply consistent, high-density energy to a broad range of APX and XPR series portable transceivers. Integrating the Motorola PMNN4491E into your operational framework provides the stable power required for maximum transmission output and pristine audio execution over long, demanding shifts. This model represents the current factory-authorized revision, serving as the direct upgrade replacement for previous legacy part numbers PMNN4491, PMNN4491A, PMNN4491B, PMNN4491C, and PMNN4491D.
Perfect for public safety personnel, heavy manufacturing environments, municipal public works crews, and field logistics operators, the Motorola PMNN4491E handles harsh real-world conditions without experiencing power drops. It features an exceptional IP68 submersibility rating, ensuring the battery housing remains entirely dust-tight and fully sealed against deep water immersion. Equipped with advanced IMPRES adaptive charging algorithms, the battery intelligently updates its own cell performance logging and calibration metrics natively when docked in a compatible charger, bypassing the need for manual, time-consuming reconditioning cycles.
To safeguard the structural lifecycle of the lithium cells, operators should charge the pack exclusively within factory-certified IMPRES single or multi-unit desktop cradles. Maintain clean electrical interface plates on the rear of the battery casing, as dirt or oil buildup can impede the telemetry bridge between the battery microchip and the transceiver or staging station.
