*) 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 incorrectly
connected, the reverse polarity protec-
tion will ensure that the battery and
charger are not damaged.
For batteries mounted inside a
vehicle
1. Connect the red clamp to the battery'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 positively
earthed batteries.
1. Connect the black clamp to the battery's
negative pole.
2. Connect the red clamp to the vehicle chas-
sis 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.
