Replacement battery for CP200 series

The BatteryJack NNTN4970A is a 2150mAh replacement battery built for Motorola CP200, CP150 and EP450 two-way radios. It fits the same form factor as the original NNTN4496 cell and ships new with an 18 month warranty. Professional users who rely on daily radio contact can swap it in without tools.

Sustained shift performance

The 2150mAh capacity supports extended transmit and receive cycles across a full work shift. Output voltage remains stable during repeated key-ups, so audio clarity does not fade as the pack discharges. Users who need multi-day standby between charges should note the single-pack design limits total reserve.

Thermal and power behaviour

The pack runs cool during typical push-to-talk duty because current draw stays moderate. No active cooling is required and the radio chassis dissipates the small heat load silently. Charging follows the radio’s standard desk or multi-unit charger profile with no extra power equipment needed.

Questions about this item

How much heat does the 2150mAh pack generate during a full day of transmit cycles?

The battery is a passive NiMH cell; it warms slightly under heavy transmit but has no active cooling and no published thermal rating.

Which charger cradle or desktop unit must I already own to charge this NNTN4970A pack?

Any Motorola single- or multi-unit charger designed for the CP200, CP150 or EP450 battery form factor will charge this pack.

Will the NNTN4496 reference on the label cause fit issues with my older CP200 housing?

NNTN4496 is an alternate Motorola part number for the same physical shell, so the pack seats identically in CP200, CP150 and EP450 radios.
