Replacement battery for Kenwood two-way radios
This 7.4 V lithium-ion pack replaces the original KNB-24L, KNB-35L, KNB-55L, KNB-56N, KNB-57L, KNB-78L and KNB-79LC cells. It fits the TK-2140, TK-2148, TK-2160, TK-2168, TK-2170, TK-2170M, TK-2173, TK-2360, TK-3140, TK-3148, TK-3160, TK-3168, TK-3170, TK-3173, TK-3178, TK-3360, NX-220, NX-320, NX3200, NX3220, NX3300 and NX3320 models. The 2000 mAh capacity delivers 14.80 Wh of energy for extended field use.
Upgrading from lower-capacity packs
Users moving from the 55 or 56 series batteries gain extra talk time without changing form factor. The fully decoded chip communicates with the radio exactly as the factory unit does, so no firmware updates or calibration routines are required. ISO9001, RoHS and CE certifications confirm the cells meet the same safety baselines as the original equipment.
Sustained discharge in daily service
The pack measures 100.60 x 55.80 x 16.90 mm and weighs 107.0 g, matching the OEM footprint for secure belt-clip mounting. Built-in overcharge, over-discharge, over-voltage and short-circuit protection prevents cell damage during long shifts. After two or three full charge cycles the chemistry settles to its rated capacity, maintaining consistent voltage through the duty cycle.
