Reliable power for Kenwood two-way radios

This 7.4 V 2600 mAh lithium-ion pack replaces the KNB-48L cell used in Kenwood NX200 and NX300 portable radios. It supplies the voltage and capacity those handsets expect for daily voice and data communication.

Capacity and headroom for shift-length use

The 2600 mAh rating delivers extended talk time on a single charge, supporting full-shift operation in typical duty cycles. Heavy transmit users or very cold environments will drain the pack faster and may need a spare for uninterrupted coverage.

Drop-tested construction fits existing chargers

The housing survives six drops from six feet onto all sides without cracking or losing output, so it endures rough handling on site. It slots into standard Kenwood desktop chargers and radio battery rails, requiring no adapter or firmware change.

Questions about this item

Will the 7.4 V 2600 mAh Tank battery fit my Kenwood NX-200 and NX-300 radios without modification?

Yes, the Tank battery is built to the KNB-48L form factor and is listed as compatible with Kenwood NX-200, NX-300 and other radios that use the KNB-48 series pack.

How can I confirm the new Tank pack is delivering its rated 2600 mAh after the first charge?

Charge the pack fully, then run the radio on a typical duty cycle; a healthy 2600 mAh Li-ion cell should provide several hours of transmit/receive time before the low-battery alert sounds.

Does the package include a charger or only the 7.4 V 2600 mAh battery itself?

Only the Tank KNB-48L battery is supplied; a compatible Kenwood or third-party charger for 7.4 V Li-ion packs must be purchased separately.
