CONCEPT AND MAIN APPLICATIONS

Considering the future demand for slide type 7.2V Li-ion and Ni-MH
battery, the above product has been launched with wider changeable range.
This new face contains trickle charging function.
Its brief benefits are mentioned below.

1. Only 22 minutes for full-charge of 3.0 Ah Li-ion Battery

2. Innovative computer controlled charging system realized most suitable
charge by making the digital communication between charger and battery.

3. Cooling system to keep the ideal temperature for charge.

4. Power display for battery; It displays the charging amounts of battery
in two steps. (less than 80% or more than 80% of charge)

5. The adapter ADP04 (optional accessory) enables to charge the existing
Ni-Cd and Ni-MH batteries.

6. The adapter ADP03 (optional accessory) enables to refresh inactive
batteries

7. Selectable melody sound of completed charging
