Replacement Battery for Kenwood Radios

This 7.2V 2100mAh Ni-MH pack replaces Kenwood KNB-16, KNB-16A, KNB-17, KNB-17A, KNB-21, KNB-21N, KNB-22 and KNB-22N cells. It fits the TK-190, TK-280, TK-290, TK-380, TK-390, TK-480, TK-481, TK-490, Pro Talk TK-2100, TK-4100 and TK-5400 two-way radios. Operators needing a direct OEM substitute for fleet or personal use will find the correct voltage and connector here.

Sustained Transmission Performance

The 2100mAh Ni-MH chemistry delivers stable voltage across long talk cycles, reducing the voltage sag that cuts range on depleted cells. Capacity holds through repeated charge cycles without the memory effect that plagued older nickel-cadmium packs. Users running extended shifts on the TK-480, TK-380 or TK-5400 platforms gain reliable push-to-talk time between charges.

Simple Slide-On Installation

The battery mates with the radio's existing latch rails; no tools or soldering are required. Alignment tabs prevent reverse insertion, and the pack clicks securely into the TK-280, TK-380 or TK-480 chassis. The only common issue is corrosion on aged radio contacts, which should be cleaned before fitting the new cell to ensure full current transfer.

Questions about this item

Does the 7.2V 2100mAh Ni-MH pack run hot or draw extra current during all-day transmit cycles?

Ni-MH chemistry at 7.2V and 2100mAh is rated for normal duty cycles; extended high-power transmit will warm the pack but stays within typical two-way radio thermal limits.

My Kenwood TK-480 uses the original KNB-16A — is this battery a direct mechanical and electrical match?

Yes, it replaces Kenwood KNB-16, KNB-16A, KNB-17, KNB-17A, KNB-21, KNB-21N, KNB-22 and KNB-22N packs without adapter or modification.

Will the replacement cell fit and charge correctly in a desktop charger built for the older KNB-21 on my TK-280?

The pack shares the same 7.2V Ni-MH profile and form factor as the KNB-21, so existing desktop chargers for the TK-280 series will recognise and charge it normally.
