cable is connected to the wall socket. The error lamp will indicate if the battery clamps
are incorrectly connected. The reverse polarity protection will ensure that the battery
or charger will not be damaged.
3. Press the MODE-button to select charging program.
4. Follow the indication lamps through the charging process.
The battery is ready to start the engine when is lit.
The battery is fully charged when is lit.
5. Stop charging at any time by disconnecting the mains cable from the wall socket.

CHARGING PROGRAMS
Settings are made by pressing the MODE-button. After about two seconds the charger
activates the selected program. The selected program will be restarted next time the
charger is connected.
The table explains the different Charging Programs:
Program Battery
Size (Ah) Explanation Temp range
NORMAL 14–225Ah Normal battery program
14.4V/7A. Use for WET batteries,
Ca/Ca, MF and for most GEL batteries
+5°C–+50°C
(41ºF–122ºF)
AGM
14–225Ah
AGM battery program 14.7 V/7A
Use for AGM batteries. -20°C–+5°C (-4ºF–41ºF)
RECOND 14–225Ah
Recond program 15.8V/1.5A
Use to return energy to the empty
WET and Ca/Ca batteries. Recond
your battery once per year and after
deep dischare to maximise lifetime and
capacity. The Recond program adds the
Recond step to the normal battery
program. Frequent use of the Recond
program may cause water loss in the
batteries and reduce service life of
electronics. Contact your vehicle and
battery supplier for advice.
-20°C–+50°C
(-4ºF–122ºF)
14–225Ah
Supply program 13.6V/7A
Use as 12V power supply or use for
float maintenance charging when 100%
capacity of the battery is required.
Supply program activates Float step
without time or voltage limitation.
-20°C–+50°C
(-4ºF–122ºF)
ERROR LAMP
If the error lamp is lit, check the following:
1. Is the chargers positive lead connected to the
batterys positive pole?
2. Is the charger connected to a 12V battery?
3. The clamps are short circuited?
4. Has charging been interrupted in or ?
Restart the charger by pressing the MODE-button. If charging is
still being interrupted, the battery...
...is seriosly sulphated and may need to be replaced.
...can not accept charge and may need to be replaced.
...can not keep charge and may need to be replaced.
WARNING!
The spark protection on the battery charger
is disabled during SUPPLY program.

STEP 1 DESULPHATION
Detects sulphated batteries. Pulsing current and voltage, removes sulphate from the lead
plates of the battery restoring the battery capacity.
STEP 2 SOFT START
Tests if the battery can accept charge. This step prevents that charging proceeds with a
defect battery.
STEP 3 BULK
Charging with maximum current until approximately 80% battery capacity.
STEP 4 ABSORPTION
Charging with declining current to maximize up to 100% battery capacity.
STEP 5 ANALYSE
Tests if the battery can hold charge. Batteries that can not hold charge may need to be replaced.
STEP 6 RECOND
Choose the Recond program to add the Recond step to the charging process. During the Recond step
voltage increases to create controlled gasing in the battery. Gasing mixes the battery acid and gives
back energy to the battery.
STEP 7 FLOAT
Maintaining the battery voltage at maximum level by providing a constant voltage charge.
STEP 8 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage and gives a
pulse when necessary to keep the battery fully charged.

*) 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.

SAFETY
• The charger is designed for charging 12V lead-acid batteries. Do not use the charger
for any other purpose.
• 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 damage 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 before leaving the charger
unattended and connected for long periods. If the charger has not switched to
within 45 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 battery 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 regulations
for electrical installations.
