Impres PMNN4491C PMNN4491B Replacement Battery for Motorola Radios

In this review of the Impres PMNN4491C/PMNN4491B replacement battery, the bottom line is straightforward: this slim, IMPRES-compatible pack is aimed at professionals who rely on Motorola XPR radios and need a dependable, long-life spare battery. The reviewer found it particularly valuable for fleets and field technicians because it matches the original size, offers IMPRES charging compatibility, and uses upgraded A++ cells with a smart IC for safety. If consistent runtime and safe charging with an IMPRES charger matter to you, this battery deserves consideration.

Key Features

• IMPRES compatibility: Works with IMPRES chargers so the battery communicates with the charger for optimized charging and battery conditioning.
• Direct fit: Same size and thickness as the original PMNN4491C/PMNN4491B battery, so it snaps into Motorola XPR models without adapters.
• Upgraded cells: Built with premium grade A++ cells to provide a longer usable life and maintain capacity through many cycles.
• Smart protection: Integrated microchip protects against over-charge, over-discharge, short circuit and overheating for safer daily use.
• Durable casing: Aluminum casing improves impact resistance and helps dissipate heat during charging and operation.
• Pack contents: The package includes one PMNN4491C/PMNN4491B battery and one belt clip for immediate field use.

Who It's For

This battery is best for users of Motorola XPR series radios such as XPR7350, XPR7380, XPR7550 and related models who need an OEM-style replacement with IMPRES functionality. It suits fleet operators, security teams, construction crews, and other professionals who depend on predictable charging and a battery that fits the radio without modification.

It is not intended for users who lack an IMPRES-capable charger, since charging with a non-IMPRES charger may not work correctly. Casual users who only need intermittent, low-duty operation and do not require IMPRES features may prefer a simpler, lower-cost pack.
