Direct replacement for Motorola CP and GP radios

This Centenex Electronics Ni-MH battery delivers 7.5 V and 2500 mAh capacity, matching the NNTN4496, NNTN4497 and NNTN4851 part numbers. It fits a wide range of Motorola two-way radios including the CP150, CP160, CP170, CP180 and CP200 series. Professional users get a ready-to-install power source for fleet or marine communication gear.

Rugged black casing with OEM-compatible contacts

The pack measures 121.00 x 60.00 x 38.16 mm and slides into the radio battery rail without adapters or soldering. Nickel-metal hydride chemistry provides stable voltage across the discharge cycle and tolerates the temperature swings common in vehicle-mounted or handheld marine use. The 18.75 Wh energy rating supports extended shift coverage.

Upgrades older Ni-Cd packs without changing chargers

Operators replacing legacy nickel-cadmium cells gain higher capacity and reduced memory effect while keeping existing charging infrastructure. The jump is worth it when radios run multiple shifts between charges or when battery swap logistics add downtime. Buyers who need lithium-ion energy density or a different voltage platform should look elsewhere.
