BatteryJack inc. 2x KNB-65L Li-ion 7.4 V 1600 mAh radio battery

Two-pack Li-ion radio batteries

This two-pack supplies 7.4 V 1600 mAh lithium-ion cells built as direct replacements for Kenwood portables including the TK-2200, TK-2207, TK-2212, TK-2300 and TK-2302 series. Each pack uses high-impact ABS and polycarbonate housing sized at 96.8 x 54.3 x 30.6 mm to survive drops and rough handling on job sites. The chemistry delivers reliable voltage for voice and signalling duties across the listed models. Buyers needing higher-capacity packs or different connector styles will need another solution.

Sustained discharge performance

Cells are tested for high-altitude operation, vibration, mechanical shock, thermal cycling, external short-circuit and overcharge simulation to verify consistent output during extended shifts. The manufacturer guarantees that each battery will retain at least 80 percent of its rated capacity for 18 months from the shipment date. This durability focus suits users who rely on radios for full work days without frequent swaps. Operators who require hot-swap charging cradles or multi-bay gang chargers should verify accessory compatibility separately.

Thermals and power draw

Lithium-ion chemistry keeps self-discharge low and maintains stable voltage under normal transmit and receive cycles. The rugged polymer case aids heat dissipation during prolonged push-to-talk use without adding active cooling. No fan, radiator or external thermal interface is present or required. Users expecting built-in fuel gauges, smart-battery telemetry or rapid-charge protocols beyond standard Li-ion CC-CV will not find those features here.
