This four-pack supplies 7.4 V 1800mAh lithium-ion cells that replace Kenwood KNB-24, KNB-24L, KNB-35, KNB-35L, KNB-55L and KNB-57L packs. They are built with high-grade cells and tested to meet or exceed OEM quality standards. The manufacturer’s plant holds ISO 9002 certification and backs the batteries with an 18-month warranty.

Verify Radio Model And Voltage

Confirm that your handheld is one of the listed Kenwood portables such as the TK-2140, TK-3140, TK-2170, TK-3170, NX-220 or NX-320 before ordering. Check that the original pack is rated at 7.4 V so the replacement voltage matches. Ensure the battery compartment accepts the standard KNB-35L form factor used by these radios.

Drop-Tested Cells For Field Reliability

Each pack survives six drops from six feet on every side without breaking or losing power, making the set suited for demanding outdoor or marine use. The four-pack lets you rotate charged cells during extended shifts without carrying a charger. No additional accessories are required beyond the radio’s existing charging cradle.

Questions about this item

Does the pack of four 1800mAh KNB-35L batteries include a charger or must I buy one separately?

The listing covers only the four replacement batteries; a compatible Kenwood charger is not included and must be purchased separately.

My radio uses the original KNB-24L pack — will these 7.4 V 1800 mAh cells work as a direct replacement?

Yes, the batteries replace OEM part numbers KNB-24, KNB-24L, KNB-35, KNB-35L, KNB-55L and KNB-57L, so they fit the KNB-24L slot directly.

What runtime can I expect from the 1800 mAh rating on a Kenwood TK-3170 during a typical shift?

The 1800 mAh capacity at 7.4 V matches the original KNB-35L specification, delivering comparable talk time to the factory pack on TK-3170 and other listed models.
