State-of-the-art technology meets VARTA design
For Ni-MH, Li-Ion and USB Devices

LCD DUAL TECH CHARGER


Trickle Charge
Prevents the natural self-discharging process of rechargeable cells
Minus Delta V method
Method which takes advantage of the fact that the cell voltage reduces slightly in a rechargeable battery (- Delta V), as soon as the cell is completely charged
Short Circuit Protection
Defective and short circuited cells will not be charged and will not harm the charger
Temperature Control
The temperature of the rechargeable battery is measured whilst it is charging. If this rises above a defined maximum temperature level the charger switches itself off
Automatic Li-Ion detection
Detects the cell chemistry and charges the Li-Ion cell to 4.2V. Enables to adapt the charging current to 1000mA for high capacity cells (>= 1000mAh)
Wrong polarity protection
Protection against reverse cell insertion
USB-out function
Charge your mobile devices by using the USB-Out Port
Individual charging channels
Enables you to charge different numbers and combinations of cells
Global Voltage
Global voltage for worldwide use
Bad cell & alkaline detection
Contains criteria for switching off to prevent charging of primary cells, defect cells or cells with reverse polarity
Compatible with Li-Ion and Ni-Mh
Charger is compatible with Li-Ion and Ni-Mh Rechargeable Batteries and can be charged at the same time
