Description
Rugged IMPRES 2 Li-Ion 2900 mAh TIA-4950 Intrinsically Safe Battery
Genuine Motorola submersible IP68 rechargeable power pack delivering extended shift runtime, smart diagnostics, and UL-certified HazLoc protection for MOTOTRBO Ion smart radios.
The Motorola PMNN4804A (catalog part PMNN4804 / PMNN4804A) is an authentic original equipment manufacturer (OEM) rechargeable lithium-ion battery pack engineered specifically for the MOTOTRBO Ion smart radio. Please note: The Motorola PMNN4805A battery has been discontinued and is no longer available; the PMNN4804A is the official direct replacement and alternative. Delivering 2900 mAh of rated capacity, this high-energy power pack ensures all-day voice, broadband LTE data, and video streaming performance under demanding operational tempos. Built with intelligent IMPRES 2 energy technology, the battery communicates directly with proprietary Motorola charging solutions to automate reconditioning, optimize cell longevity, and provide exact state-of-charge analytics.
Engineered to excel in hazardous industrial locations, the Motorola PMNN4804A is certified to UL TIA-4950 standards for Division 1, Class I, II, III, Groups C, D, E, F, G; Division 2, Class 1, Groups A, B, C, D T3C environments (Tamb = -20°C to +60°C). Its ultra-rugged enclosure achieves an IP68 ingress protection rating, capable of surviving total submersion under two meters of water for up to four hours without seal failure. Backed by Motorola Solutions' 24-month capacity warranty and 48-month workmanship warranty, this intrinsically safe battery maximizes fleet uptime across chemical processing plants, refineries, utilities, and emergency response operations under FCC Licensing standards.
