IMPRES Li-Ion IP68 2800mAh Battery

High-Capacity Smart Power for Mission-Critical Portables

The Motorola PMNN4448C is a high-capacity, professional-grade lithium-ion battery designed to provide extended talk-time and rugged reliability for high-tier portable radios. Engineered with Motorola’s exclusive IMPRES™ Smart Energy System, this battery actively communicates with IMPRES chargers to automate reconditioning and optimize its overall service life. With a substantial 2800mAh capacity, the PMNN4448C is built to support long shifts and heavy-duty communication needs, ensuring your equipment stays powered when it matters most.

Built for extreme field conditions, the Motorola PMNN4448C features an IP68 submersibility rating, making it completely dust-tight and capable of withstanding immersion in water up to two meters for two hours. The internal IMPRES technology stores critical data—including authenticity, remaining capacity, and service-life statistics—which is communicated via a unique protocol to maximize efficiency and eliminate the "memory effect." This rugged, high-density power solution is the direct successor to the PMNN4448B, offering a more durable housing for mission-critical deployments.

Key Features & Benefits

• IMPRES™ Smart Technology: Automatically communicates with chargers to perform adaptive reconditioning and maximize the battery's total number of charge cycles.
• Extended 2800mAh Capacity: Provides significantly more energy than standard batteries, ensuring clear communications across double shifts or extended incidents.
• IP68 Waterproof Rating: Delivers superior environmental protection, allowing the radio to remain functional even after complete submersion in water.
• Advanced Data Tracking: Stores unique service-life data within the battery, allowing fleet managers to track performance and predict replacement needs.
• Authenticity Guaranteed: Integrated circuitry ensures only genuine Motorola batteries are used with your high-value radio assets, protecting internal electronics.
• Ruggedized Construction: Manufactured with high-impact materials to withstand the drops, vibrations, and thermal shocks common in industrial and public safety use.

Frequently Asked Questions

• What is the difference between this and the PMNN4448B? The PMNN4448C is the modernized replacement for the legacy PMNN4448B. While the capacity remains at 2800mAh, the "C" version often 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.
