Motorola Solutions PMNN4491 IMPRES Li-Ion Battery 2100 mAh

Optimise the daily performance of your professional two-way radio fleet with the Motorola Solutions PMNN4491 IMPRES Li-Ion Battery. Designed specifically to deliver long-lasting, reliable power for critical communication devices, this premium rechargeable unit boasts a robust 2100 mAh capacity. Built around Motorola's proprietary Intelligent Motorola Battery System (IMPRES) technology, it automatically manages power delivery and self-calibration to maximise the overall lifespan of the cell. Engineered for seamless integration with the UK-standard DP2000 and DP4000 series (including the latest 'e' variants), and complete with a rugged IP68 submersible rating, this slimline, high-density battery ensures your team stays safely connected throughout the longest shifts, whether operating in heavy rain, thick dust, or demanding industrial sites.

Intelligent Power Management for Critical Communications

When it comes to professional communication devices, reliability is absolute key. The Motorola PMNN4491 battery is driven by the Intelligent Motorola Battery System (IMPRES). This advanced technology allows the battery to communicate directly with compatible IMPRES chargers to automate reconditioning and self-calibration processes. By intelligently managing how the battery draws and stores power, the IMPRES system prevents the "memory effect" common in older cells, ensuring your battery maintains its maximum capacity over a much longer operational timeframe.

Extended Shift Performance for DP Series Radios

Field teams require reliable power to cover long working shifts without hunting for a charging station. When paired with the highly popular UK DP2000e series, this high-density 2100 mAh cell delivers an impressive operating time of up to 18.5 hours in digital mode, and 14 hours in analogue mode. This ensures that security personnel, retail staff, and logistics workers can carry their radios comfortably throughout their entire shift while benefiting from hours of uninterrupted talk time.

Rugged IP68 Environmental Protection

Field workers, emergency responders, and industrial teams cannot afford power failures due to bad weather. The PMNN4491 is built to survive extreme conditions, carrying a rigorous IP68 submersible rating. This means the internal lithium-ion chemistry is completely sealed against fine dust ingress and is protected against continuous submersion in water. Whether your team is operating in torrential rain, dusty construction sites, or demanding manufacturing floors, this battery delivers consistent, unwavering performance without adding unnecessary bulk.
