BatteryJack inc. 2 x 2600mAh Li-Ion KNB-48L Battery for KENWOOD TK-5220 TK-5320 NX-200 NX-300

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.
