*) Back current drain is the current that drains the battery if the charger is not connected to the mains. CTEK chargers has 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.
