Description
High-Capacity Submersible IMPRES 2 Li-Ion Battery
Genuine Motorola 4850 mAh rugged rechargeable power pack engineered for APX and SRX series radios with IP68 submersion and extreme -30°C cold weather performance.
The Motorola PMNN4487A (catalog part PMNN4487 / PMNN4487A, previously NNTN7034B) is an authentic original equipment manufacturer (OEM) high-capacity rechargeable lithium-ion battery pack engineered for mission-critical APX and SRX series portable two-way radios. Delivering a certified 4850 mAh capacity in a streamlined profile, this power pack provides continuous operational duty across extended multi-shift schedules, mutual aid mobilizations, and prolonged emergency response operations without mid-shift recharging.
Engineered to endure severe field conditions, the Motorola PMNN4487A features an IP68 ingress protection rating that allows complete submersion in water for up to two hours without seal compromise. Built to rigorous MIL-STD-810E military durability standards for impact, vibration, and thermal shock, the internal cell architecture is certified to operate in sub-zero climates down to -30°C (-22°F). Powered by second-generation IMPRES 2 energy technology, the battery communicates directly with IMPRES chargers to automate reconditioning cycles, extend total charge cycle life, and deliver precise capacity analytics under commercial FCC Licensing standards.

Frequently Asked Questions
What does the "A" suffix at the end of part number PMNN4487A mean?
The "A" suffix indicates the latest official manufacturing revision from Motorola Solutions. PMNN4487A represents the newer, current production version of the base part number PMNN4487, and directly supersedes legacy part number NNTN7034B with updated internal IMPRES 2 management circuitry while maintaining identical physical fit and radio performance.
What radios are compatible with the Motorola PMNN4487A battery?
The PMNN4487A is engineered and certified for Motorola APX 5000, APX 6000, APX 6000Li, APX 6000XE, APX 7000, APX 7000XE, APX 8000, and SRX 2200 series portable radios.
What is the water resistance rating of the PMNN4487A?
The battery carries an IP68 ingress protection rating, allowing it to remain completely submerged in water for up to two hours without water penetration or electrical failure.
Is the Motorola PMNN4487A intrinsically safe?
No. The PMNN4487A has no intrinsic safety rating. If your operations require a UL TIA-4950 intrinsically safe / HazLoc battery for explosive environments, consider the Motorola PMNN4505A.
Can I charge this battery in older IMPRES chargers?
Yes. The Motorola PMNN4487A is backward-compatible with original Motorola IMPRES chargers (operating firmware version 3.11 or newer) as well as updated IMPRES 2 multi-unit and single-unit charging stations.
How does the PMNN4487A perform in cold winter conditions?
The battery is engineered with a specialized low-temperature electrolyte formula that guarantees dependable voltage regulation and stable power output in temperatures down to -30°C (-22°F).
Warranty
24-month capacity warranty and 48-month workmanship warranty from Motorola Solutions.
