*) 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.

INFO
If the battery clamps are incor-
rectly connected, the reverse
polarity protection will ensure that
the battery and charger are not
damaged.
For batteries mounted inside a
vehicle
1. Connect the red clamp to the bat-
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-
tively earthed batteries.
1. Connect the black clamp to the bat-
tery's negative pole.
2. Connect the red 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 red clamp before the
black clamp.
