Battery compatibility

The Bolton Technical WPLN4137 accessory pairs a 7.2 V 1800 mAh Ni-MH battery with a belt clip. It replaces Motorola part numbers NNTN4970, NNTN4496, NNTN4497 and NNTN4851 across two-way radio models including CP040, CP140, CP150, CP160, CP180, CP200, CP200D, CP200XLS, CP340, CP360, CP380, GP3188, GP3138, GP3688, PR400, EP450, EP450S and XIR-P3688.

Sustained operation

Ni-MH chemistry delivers steady voltage through a full shift without the sharp drop-off seen in short-burst tests. The 1800 mAh capacity supports extended talk time on compatible radios such as the CP200, GP3688 and PR400, and the cell fits chargers WPLN4137, WPLN4137BR and WPLN4138 for overnight replenishment.

Build and mounting

The pack includes a belt clip that secures the radio to a waistband or strap, keeping the PTT button within reach during hands-on tasks. No additional hardware is required; the battery slides into the radio chassis and locks with the original latch mechanism used on CP180, CP340 and EP450 series units.

Questions about this item

How much heat does the 7.2 V 1800 mAh Ni-MH battery generate during continuous all-day radio use?

The battery uses Ni-MH chemistry at 7.2 V and 1800 mAh, which runs cool under normal duty cycles; no active cooling is required for the supported Motorola models.

Which charger must I already own for the WPLN4137 accessory to work with this battery?

The battery fits charger models WPLN4137, WPLN4137BR and WPLN4138; one of those chargers is needed to recharge the pack.

Will the included belt clip fit my older Motorola CP140 and GP3188 radios?

Yes, the replacement battery replaces OEM part numbers NNTN4496, NNTN4497 and NNTN4851, so it mounts directly on CP140, GP3188 and the other listed radios.
