Frequently Asked Questions
Which radio models are compatible with the Motorola PMNN4600A battery?
The PMNN4600A is designed specifically for the Motorola MOTOTRBO R2 series portable two-way radio (both analog-only and digital/analog DMR versions).
Does the PMNN4600A feature IMPRES technology?
No. The PMNN4600A is a standard Motorola Original Li-Ion battery. It does not contain IMPRES microchip diagnostic telemetry, but charges reliably in standard Motorola R2 single-unit (PMPN4572) and multi-unit (PMPN4576) desktop chargers.
What does the IP55 rating mean for this battery?
An IP55 rating indicates that the battery housing is sealed against harmful deposits of dust and is protected against water projected from a nozzle (low-pressure water jets) from any direction, making it suitable for rain and outdoor jobsite conditions.
Should I turn off the MOTOTRBO R2 radio before charging?
Yes. To ensure optimal battery life, prevent thermal buildup, and allow the charging dock to accurately measure cell voltage, always turn the radio OFF before placing it into the charging cradle.
Is the PMNN4600A intrinsically safe for hazardous locations?
No. The PMNN4600A carries no intrinsic safety rating and is not certified for HAZLOC or explosive environments. For classified hazardous environments requiring TIA4950 UL certifications, an approved intrinsically safe battery model must be used.
