SWIT S-3602U P-U Charger (Used)

S-3602U is a dual channel charger designed for SWIT S-8U63 and SONY BP-U series batteries. It features intelligent dual channel charging, with 2 charging channels and a total output of DC 16.7V, 1.9A. The charger can sequentially charge 2 batteries to 75% capacity before charging both simultaneously to full. Each channel is equipped with 4-level LED charging indicators to show real time capacity by percentage. Additionally, the charger has a 5.5mm/2.1mm pole socket of DC12V, 1.9A adapting output for convenience.

With advanced charging curve technology, the charger follows a two-period approach for Li-ion batteries. The first period is constant-current, charging the battery at the maximum rate. Then, the charging circuit switches to the second period, constant-voltage, to maintain the set-point voltage and prevent overcharging. Multiple safety protections are also built in, including identification of battery types and correct charging program, to prevent overcurrent, overcharging, and high temperature.
