Replacement Battery for Kenwood Radios

This 7.4V 1800mAh lithium-ion pack replaces OEM part numbers KNB-24, KNB-24L, KNB-35, KNB-35L, KNB-55L and KNB-57L. It fits Kenwood portable models including the TK-2140, TK-3140, TK-2148, TK-3148 and NX-220 series. The cells are built to meet or exceed original quality standards.

Compatibility Check Before Ordering

Verify the exact model number printed on your radio matches the supported list such as TK-2160, TK-3160, TK-2170 or TK-3360. Confirm the original battery part number is one of the KNB codes listed above. The pack uses a 7.4V chemistry so the radio must accept this voltage.

Build Integration and Benefits

The ruggedised housing survives six drops from six feet on every side without breaking or losing power. Using highest-grade cells ensures reliable output during extended shifts. An eighteen-month warranty backs the manufacturing quality from an ISO9002 certified plant with over ninety-five years of combined industry experience.

Questions about this item

Does the replacement battery ship with a charger or only the pack?

The listing covers the 7.4 V 1800 mAh lithium-ion pack itself; a charger is not included and must be sourced separately.

The description lists several OEM part numbers such as KNB-24L and KNB-57L — which one should I order?

This single pack replaces all listed OEM numbers including KNB-24, KNB-24L, KNB-35, KNB-35L, KNB-55L and KNB-57L, so any of those references point to the same unit.

What run-time can I expect from the 1800 mAh rating on a Kenwood TK-3140?

The 1800 mAh capacity typically delivers a full shift of mixed transmit and receive use on compatible models such as the TK-3140, though actual time varies with power setting and duty cycle.
