Charging time
2h Charging time
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
12V Car Adapter
Including 12V adapter. This makes it possible to charge you rechargeable batteries while driving
Bad cell & alkaline detection
Contains criteria for switching off to prevent charging of primary cells, defect cells or cells with reverse polarity
Trickle Charge
