SAFETY
• The charger is designed for charging 12V lead-acid batteries.
• Check the charger cables prior to use. Ensure that no cracks have occurred in the
cables or in the bend protection. A charger with damaged cables must not be used.
A damaged cable must be replaced by a CTEK representative.
• Never charge a damaged battery.
• Never charge a frozen battery.
• Never place the charger on top of the battery when charging.
• Always provide for proper ventilation during charging.
• Avoid covering the charger.
• A battery being charged could emit explosive gasses. Prevent sparks close to the
battery. When batteries are reaching the end of their lifecycle internal sparks may
occur.
• All batteries fail sooner or later. A battery that fails during charging is normally
taken care of by the chargers advanced control, but some rare errors in the battery
could still exist. Don’t leave any battery during charging unattended for a longer
period of time.
• Ensure that the cabling does not jam or comes into contact with hot surfaces or
sharp edges.
• Battery acid is corrosive. Rinse immediately with water if acid comes into contact
with skin or eyes, seek immediate medical advice.
• Always check that the charger has switched to STEP 7 before leaving the charger
unattended and connected for long periods. If the charger has not switched to STEP 7
within 50 hours, this is an indication of an error. Manually disconnect the charger.
• Batteries consume water during use and charging. For batteries where water can
be added, the water level should be checked regularly. If the water level is low add
distilled water.
• This appliance is not designed for use by young children or people who cannot
read or understand the manual unless they are under the supervision of a responsible
person to ensure that they can use the battery charger safely. Store and use the bat-
tery charger out of the reach of children, and ensure that children cannot play with
the charger.
• Connection to the mains supply must be in accordance with the national regula-
tions for electrical installations.

*) 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 eect 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 con-
nected, 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 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 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.
