*) Back current drain is the current that drains the battery if the charger is not connected
to the mains. CTEK chargers have a very low back current.
**) The quality of the charging voltage and charging current is very important. A high
current ripple heats up the battery which has an aging effect on the positive electrode.
High voltage ripple could harm other equipment that is connected to the battery. CTEK
battery chargers produce very clean voltage and current with low ripple.
