Replacement Ni-MH Battery for Kenwood Radios

The Estry TK-190 is a 7.2V 1800mAh nickel-metal hydride pack built to match the original specifications for a wide range of Kenwood two-way radios. It serves professionals and organisations that need reliable power for daily voice and data communication in the field.

Sustained Capacity and Protection Circuitry

The 12.96Wh cell delivers consistent output across a full duty cycle rather than fading after a short burst. Integrated overcharge, over-discharge, over-voltage and short-circuit protection helps maintain cell health during repeated shift-length use.

Verify Model and Part Number Before Ordering

Check that your radio appears in the supported list such as TK-190, TK-385, TK-480 or TK-5400 and that the original battery part number matches KNB-17N, KNB-21N, KNB-17A, KNB-52N or KNB-16A. Buyers with radios outside this compatibility list cannot use this pack.
