Battery replacement for Kenwood radios

This 1800mAh lithium-ion pack replaces the KNB-33L cell used in Kenwood TK-2180, TK-3180, TK-5210 and TK-5310 portable two-way radios. It delivers 7.4V output and is built with high-grade cells to meet or exceed the original equipment specifications. The battery is new and carries an 18-month warranty from the supplier.

Suits fleets needing drop-rated reliability

Teams that require a power source tested to survive six drops from six feet onto all sides will find this unit appropriate. It is not suited for users of other radio brands or Kenwood models outside the listed compatibility range. Buyers who need a higher capacity than 1800mAh or a different voltage should look elsewhere.

Fits directly into compatible handsets

The pack slides into the battery cavity of the supported Kenwood portables without adapters or sleds. It frees the operator from carrying spare OEM cells that may cost more while delivering equivalent voltage and runtime. No additional charging hardware is required beyond the standard radio charger.
