Motorola PMNN4077D IMPRES Li-ion 7.4V 2400mAh Battery - Reliable Power

Our review of the Motorola PMNN4077 PMNN4077D IMPRES Li-ion battery finds it best suited for MOTOTRBO radio users who need dependable long shifts and resilience in demanding environments. The bottom line: this is an OEM replacement battery that prioritizes runtime and battery health through IMPRES compatibility, making it a practical upgrade for fleets that already use IMPRES chargers. For teams running XPR radios in field service, public safety, or industrial settings, the combination of 2400 mAh capacity and IMPRES communication features is the single biggest reason to choose this pack.

Key Features

• Original OEM construction: Provides a direct replacement that matches Motorola factory specifications for fit and performance.
• 2400 mAh high capacity: Extends talk and standby time so radios can last longer between charges during long shifts.
• IMPRES intelligence: Stores battery data and communicates with compatible chargers to optimize cycle life and reconditioning automatically.
• Submersible design: Built to withstand harsher environments where moisture or splashes are a concern for rugged radio use.
• Wide radio compatibility: Works with key XPR models including XPR 6100, 6300, 6350, 6380, 6500, 6550, and 6580 for easy fleet integration.
• Charger requirement noted: Uses IMPRES chargers such as WPLN4232A, WPLN4212A, and WPLN4219A to enable advanced features and warranty benefits.

Who It's For

Field technicians, facility managers, and public safety teams using Motorola MOTOTRBO XPR series radios will get the most from this battery because it extends operational periods and integrates with IMPRES chargers to manage battery health. The OEM nature means fewer compatibility headaches when swapping packs across a fleet of XPR radios.

Users who do not have an IMPRES charger or who need lower-capacity, lighter options for occasional use should consider basic Li-ion packs or third-party slimmer batteries instead. This battery is aimed at duty use and fleet applications rather than casual or single-shift weekend use.
