BatteryJack inc. Li-ion 1800 mAh 7.5 V for Motorola CP185 EP350 CP477

SKU CH-ZC9G-WFBZ0

Replaces Motorola PMNN4080, PMNN4081 and PMNN4082 packs in CP185, EP350 and CP477 radios with a 7.5 V 1800 mAh Li-ion cell

  • 1800 mAh capacity keeps Motorola CP185, EP350, CP477 radios running longer
  • 5 V lithium-ion chemistry provides stable voltage for clear two-way communication
  • High-impact ABS and polycarbonate housing survives six 6-foot drops on every side
  • Tested for altitude, vibration, shock, thermal cycling and short-circuit resilience
  • Guaranteed to hold at least 80 % rated capacity for 18 months from shipment

Compatible two-way radio battery

This 7.5 V 1800 mAh lithium-ion cell replaces Motorola PMNN4080, PMNN4081 and PMNN4082 packs. It fits CP185, EP350 and CP477 handsets as well as the PR400 model. High-impact ABS and polycarbonate housing is tested to survive six drops from six feet on every side. The pack is guaranteed to hold at least 80 percent of rated capacity for 18 months from shipment.

Suits professionals needing rugged drop protection

Teams that require a battery certified for high-altitude, vibration, shock and thermal-cycling tests will benefit from the comprehensive validation programme. Users who need a different voltage, chemistry or form factor should look at other options. Buyers wanting a longer capacity guarantee than 18 months will not find it here. The cell is not designed for radios outside the listed Motorola series.

Steady output under sustained load

The lithium-ion chemistry delivers consistent discharge characteristics during extended transmit cycles. Testing includes external short-circuit and overcharge simulations to confirm stable behaviour when the radio is keyed for long periods. Capacity retention stays above the 80 percent threshold throughout the 18-month warranty window. No active cooling or thermal throttling is required in normal operation.
