Motorola PMNN4809A battery

Main features

IMPRES Self-Calibration Technology
The PMNN4809 battery features IMPRES intelligent technology, enabling it to automatically execute battery maintenance procedures. Unlike traditional batteries that require manual reconditioning cycles, the PMNN4809 automatically calibrates itself during the charging process; compared to standard Li-ion batteries, this maximizes talk time and extends the battery's overall lifespan by up to 43%. This automatic optimization capability not only reduces device management costs but also ensures that the battery maintains consistent performance throughout its entire service life.

Extended Battery Life
Boasting a large capacity of 2850mAh, this Motorola R7 battery delivers over 25 hours of talk time in digital mode when paired with R7 series two-way radios. This high-capacity performance supports continuous operation across multiple shifts, eliminating the need to swap batteries midway through the workday—a critical advantage for applications in security, logistics, and industrial sectors.

IP68-Rated Protection and Rugged Design
The PMNN4809 battery holds full IP68 certification, featuring a complete dust-tight seal and the ability to withstand immersion in water up to 2 meters deep for extended periods without sustaining damage. This level of protection ensures reliable battery performance even under the most demanding environmental conditions.
