Compatible Kenwood radios

This twin pack supplies two 7.4 V 2600 mAh lithium-ion cells that fit Kenwood TK-5220, TK-5320, NX-200 and NX-300 two-way radios. It replaces the original KNB-47, KNB-47L, KNB-48 and KNB-48L batteries, giving crews a ready spare for each handset. The set suits teams that keep multiple units on shift and need a direct drop-in replacement.

Sustained shift performance

Each cell delivers 2600 mAh at the rated 7.4 V, supporting extended talk time across a full work period rather than a brief burst. The chemistry is built to hold voltage steadily under continuous transmit cycles, so audio stays clear late into the day. Packs are assembled with grade-A cells and tested to meet or exceed the original equipment quality checks.

Upgrade from depleted OEM packs

The pair replaces worn KNB-47 or KNB-48 series batteries that no longer hold a charge through a complete rotation. Swapping both units at once restores balanced runtime across the fleet and avoids mixing old and new cells. The move is worthwhile when existing packs show reduced receive time or fail to complete a standard shift.

Questions about this item

How much heat does the 7.4V 2600mAh Li-Ion pack generate during continuous transmit cycles?

The battery uses highest-grade cells that meet or exceed OEM quality testing, keeping thermal output within the original Kenwood design limits for TK-5220 and NX-300 radios.

Which Kenwood charger is required to recharge these KNB-48L replacements?

The packs are compatible with the OEM KSC-32 charger used by TK-5220, TK-5320, NX-200 and NX-300 radios.

Will these 2600mAh packs fit the battery compartment of my older TK-5220 without modification?

They replace OEM part numbers KNB-47, KNB-47L, KNB-48 and KNB-48L, so they seat directly in the existing TK-5220 and NX-200 battery wells.
