Replacement Kenwood KNB-48L battery

This 7.4 V 2600 mAh lithium-ion pack powers compatible Kenwood two-way radios. It is built for professionals who need reliable communication in marine, automotive or field-service environments. The cell chemistry and voltage match the original KNB-48 specification.

Drop-tested durability upgrade

The pack survives six drops from six feet onto every side without breaking or losing power. That ruggedness replaces standard packs that can crack or fail after a single impact. The jump is worth it when radios are used on decks, in vehicles or on job sites where drops are routine.

Direct fit for Kenwood NX series

The battery slides into the radio battery rail with no adapter or modification required. It frees the operator from carrying bulky spare packs because the high-capacity cells extend talk time per charge. The 18-month warranty covers the cells against premature capacity loss.

Questions about this item

Will the KNB-48L battery fit my Kenwood NX200 radio?

Yes, the KNB-48L is a direct replacement for the original Kenwood KNB-48 battery and fits the NX200, NX300, TK-5220 and TK-5320 models.

How do I install the KNB-48L battery, and what mistake should I avoid?

Slide the battery onto the radio chassis until the locking latch clicks; the common error is stopping before the latch fully engages, leaving the pack loose.

When will the KNB-48L need replacement, and what does the warranty cover?

The 18-month warranty covers defects; after that, replace the pack when talk time drops noticeably below the rated 2600 mAh capacity.
