Key features & benefits

• IMPRES Self Calibration — Eliminates the need for long monthly calibration or reconditioning sessions. When charged and maintained with IMPRES Single Unit Chargers and IMPRES 2 Multi Unit Chargers listed in the radio's Authorized Accessories List, the battery self-calibrates automatically, keeping it mission-ready without manual intervention.
• IP67 Environmental Protection — The PMNN4888A carries an IP67 ingress-protection rating, meaning the battery is dust-tight and protected against temporary immersion in water—an important resilience attribute for field personnel working in harsh or unpredictable environments.
• 2200mAh Slim Lithium-Ion Design — The slim form factor keeps the radio's profile low and weight down while delivering a 2200mAh Li-Ion capacity engineered to maximize talk time. Slim batteries are ideal for environments where a lower-profile radio body improves comfort during extended wear.
• Intelligent IMPRES Charger Communication — IMPRES technology enables the battery and charger to communicate via a proprietary protocol. This adaptive interaction is designed to maximize talk time and optimize battery cycle life automatically, reducing fleet maintenance overhead.
• R5 Series Compatibility — Specifically designed for the MOTOTRBO R5 Series, covering both the No-Keypad (NKP) and Limited-Keypad (LKP) radio variants, ensuring a verified mechanical and electrical fit without the risk of mismatched accessories.
• Updated Revision (PMNN4888A) — The 'A' suffix designates this as the current production revision of the PMNN4888 battery, incorporating any improvements or compliance updates Motorola Solutions applied since the original release.
