Two-Pack Kenwood Radio Batteries

This set supplies two 7.2V 1200mAh Ni-CD cells compatible with Kenwood TK-2100, TK-3100 and TK-3101 series portables. It replaces KNB-14, KNB-15 and KNB-20N packs so crews can keep handsets running during shifts.

Drop-Tested Durability Upgrade

Each cell survives six drops from six feet on every face without cracking or losing power. The rugged build suits teams that previously lost packs to rough handling on site or in vehicles.

Field Crews Needing Spare Packs

Ideal for operations that rotate batteries through tri-chemistry chargers and want a ready spare. Not suited for users who need higher capacity than 1200mAh or a different voltage platform.
