Capacity And Voltage Details

The lithium-ion cell delivers 2100mAh capacity at 7.2V, providing 15.12Wh of energy for extended talk time. It measures 111.87 x 57.55 x 20.54mm and weighs 207.0g. A fully decoded chip ensures communication with the radio matches the original equipment. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection circuits.

Installation And Use Limits

Users who need a higher capacity pack for longer shifts should look at larger alternatives, as this unit is fixed at 2100mAh. Buyers with radios outside the listed Kenwood models cannot use this battery due to connector and firmware mismatch. The battery reaches peak performance after two or three full charge cycles. Avoid low-quality third-party chargers to maintain cell health.
