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
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
Trickle Charge
Prevents the natural self-discharging process of rechargeable cells
Short Circuit Protection
Defective and short circuited cells will not be charged and will not harm the charger
Bad cell & alkaline detection
Contains criteria for switching off to prevent charging of primary cells, defect cells or cells with reverse polarity
Ready To Use
For immediate usage straight from the pack.
3 years guarantee
