Bad cell & alkaline detection
-Contains criteria for switching off to prevent charging of primary cells, defect cells or cells with reverse polarity.
-Prevents the natural self-discharging process of rechargeable cells.
-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.
-A timer switches off after a specified time irrespective of charging status.
