Compatible Kenwood Radio Models

This replacement battery fits Kenwood NX-100, NX-200 and NX-300 series radios using the KNB48 form factor. It is built for professionals who rely on two-way communication in marine, automotive or field-service environments. The 7.4V 2600mAh lithium-ion pack delivers the voltage and capacity the original equipment specifies. Buyers needing a different voltage or connector should verify their radio model before ordering.

Durability and Thermal Behaviour

The supplier states the pack survives six drops from six feet onto all six sides without breakage or loss of function. That ruggedisation helps the cells maintain stable temperature during extended transmit cycles in harsh conditions. No acoustic noise is generated by the battery itself. The 2600mAh capacity supports typical duty cycles without excessive heat build-up.

Warranty and Cell Quality

An 18 month warranty covers defects in materials and workmanship, giving a clear service window for fleet managers. Only highest-grade cells are used, which reduces the risk of premature capacity fade compared with lower-tier packs. No software, chargers or mounting hardware are bundled with this battery.

Questions about this item

How do I install the KNB48 battery into my Kenwood NX-200 radio, and what is the common mistake?

Align the battery rails with the radio grooves, slide upward until the latch clicks, then verify the 7.4V label faces outward. The common mistake is stopping before the latch fully engages, leaving the 2600mAh pack loose.

What maintenance will the KNB48 Li-ion pack need over its service life?

Store at roughly half charge if unused for weeks, keep contacts clean with a dry cloth, and avoid full discharges. After about 18 months of regular cycling the 2600mAh capacity will gradually fade, signalling replacement.

What is the first limit I will hit when using the KNB48 continuously on high power transmit?

The 2600mAh capacity sets runtime; on high-power TX the pack typically depletes in a few hours before the 7.4V output drops below the radio's operating threshold.
