*) 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 cur-
rent 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.

tery's positive pole.
2. Connect the black clamp to the
vehicle chassis remote from the fuel
pipe and the battery.
3. Connect the charger to the wall
socket
4. Disconnect the charger from the
wall socket before disconnecting
the battery
5. Disconnect the black clamp before
the red clamp.
Some vehicles may have posi-
