Description
Motorola PMNN4448C IMPRES Li-Ion IP68 2800mAh Battery
High-capacity IMPRES smart battery with IP68 submersibility for mission-critical MOTOTRBO portables. Successor to the PMNN4448B.
The Motorola PMNN4448C is a high-capacity, professional-grade lithium-ion battery designed for extended talk-time and rugged reliability in high-tier portable radios. Engineered with Motorola’s IMPRES™ Smart Energy System, it actively communicates with IMPRES chargers to automate reconditioning and optimize service life. With a 2800 mAh capacity and IP68 submersibility rating — dust-tight and capable of withstanding immersion up to two meters for two hours — the PMNN4448C is built for long shifts and heavy-duty deployments. It is the direct successor to the PMNN4448B, with improved housing durability and seal integrity.

Frequently Asked Questions
What is the difference between this and the PMNN4448B?
The PMNN4448C is the modernized replacement for the PMNN4448B. While the capacity remains at 2800 mAh, the “C” version includes manufacturing updates to improve long-term seal integrity and housing durability.
Can I charge this battery on a non-IMPRES charger?
Yes, the battery will charge on most standard Motorola-compatible chargers. However, you will not benefit from the automated reconditioning, data tracking, and life-extension features that an IMPRES charger provides.
Is this battery safe for use in explosive environments?
No. The PMNN4448C does not carry an Intrinsic Safety (IS) rating. For hazardous locations requiring TIA-4950 or FM certification, a specific UL-rated or HAZLOC battery must be used.
Warranty
