Two-pack Li-ion batteries for Kenwood radios

This pack contains two 7.4 V 1800 mAh lithium-ion batteries built to replace Kenwood KNB-24L, KNB-35L, KNB-55L and KNB-57L cells. They fit portable models including the TK-2140, TK-3140, TK-2160, TK-3160, TK-2170, TK-3170, NX-220 and NX-320 series. The cells are assembled using high-grade components and the manufacturer’s plant holds ISO 9002 certification.

Voltage and capacity match OEM specs

Each battery delivers 7.4 volts and 1800 mAh, matching the original equipment ratings for the listed Kenwood radios. This electrical parity means the packs slot straight into existing chargers and radio bays without adapter cables or firmware updates. The supplier states the units meet or exceed OEM quality-control testing.

Suits fleets needing drop-in replacements.

Organisations standardising on the compatible Kenwood handhelds can keep spares interchangeable across multiple model numbers. Users of non-Kenwood radios or models outside the listed series should verify connector pin-out and voltage before purchasing.

Questions about this item

How long will the 1800mAh capacity actually run a TK-2140 on a typical shift?

The 1800mAh cells deliver the same runtime as the original KNB-24L pack, giving a full duty cycle on Kenwood TK-2140 and TK-3140 series radios.

What connector standard does this pack use to mate with the radio?

It uses the standard Kenwood slide-on battery interface found on the TK-2140, TK-3140, NX-220 and NX-320 models, locking securely without adapters.

Will the pack fit the existing belt clip and holster on a TK-3160?

Yes, the housing matches OEM dimensions for the KNB-24L and KNB-35L, so it slides into the same belt clips and chargers used with TK-3160 and TK-3170 radios.
