*) Back c urrent 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 c urren t ripple heats up the battery which
has an aging eff ect on the positive electrode. High voltage ripple could h arm other equipment that is connected to the battery.
CTEK battery chargers produce very clean voltage and current with low ripple.
