SKU CH-NNKX-G7BRQ

Two 7.5 V 1800 mAh Li-ion packs replace Motorola CP185, EP350 and CP477 radio batteries

  • Reliable power for Motorola CP185, EP350, CP477 radios
  • 5 V 1800 mAh lithium-ion cells deliver extended talk time
  • Survives six 6-foot drops on every side
  • Guaranteed to hold 80 % capacity for 18 months
  • Tested for altitude, vibration, shock and thermal extremes

Two-Pack Li-Ion Radio Batteries

This two-pack supplies 7.5 V 1800 mAh lithium-ion cells built for Motorola CP185 EP350 CP477 two-way radios. Each unit uses high-grade cells wrapped in high-impact ABS and polycarbonate for rugged daily use. The pack targets teams that need reliable spares for fleet or field operations. Condition is new and ready for immediate deployment.

Replaces PMNN4080 PMNN4081 Originals

The batteries directly replace Motorola PMNN4080 and PMNN4081 packs used in CP185 PR400 models. Swapping is worth it when existing packs no longer hold a full shift charge or show physical wear. Guaranteed capacity retention of 80 percent for 18 months from shipment backs the upgrade decision. An 18 month warranty and 30 day money-back guarantee cover the transition.

Sustained Field Performance

Comprehensive testing covers high altitude vibration mechanical shock thermal cycling external short circuit and overcharge simulations. The rugged housing survives six drops from six feet on all sides without breakage or power loss. Cells maintain stable discharge through long talk cycles rather than short bursts. Performance stays consistent across the warranted 18 month service window.
