MANUAL
•THE CHARGER IS DESIGNED FOR CHARG-
ING ONLY BATTERIES ACCORDING TO THE
TECHNICAL SPECIFICATION. DO NOT USE
THE CHARGER FOR ANY OTHER PURPOSE.
ALWAYS FOLLOW BATTERY MANUFACTUR-
ERS RECOMMENDATIONS.
•NEVER TRY TO CHARGE NON RECHARGE-
ABLE BATTERIES.
•CHECK THE CABLES PRIOR TO USE. ENSURE
THAT NO CRACKS HAVE OCCURRED IN
THE CABLES OR BEND PROTECTION. A
CHARGER WITH DAMAGED CABLES MUST
NOT BE USED. A DAMAGED CABLE MUST
BE REPLACED BY AN ORIGINAL PART SUP-
PLIED BY CTEK.
•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 VENTILA-
TION DURING CHARGING.
•AVOID COVERING THE CHARGER.
•A BATTERY BEING CHARGED COULD EMIT
EXPLOSIVE GASES. PREVENT SPARKS CLOSE
TO THE BATTERY.
•ALL BATTERIES FAIL SOONER OR LATER. A
BATTERY THAT FAILS DURING CHARGING IS
NORMALLY TAKEN CARE OF BY THE CHARG-
SAFETY
ERS 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 IMME-
DIATELY WITH WATER IF ACID COMES INTO
CONTACT WITH SKIN OR EYES, SEEK IMME-
DIATE 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
55 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.

*) Back current drain is the current that drains the battery if the charger is not connected
to the mains. CTEK chargers have 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.

CHARGING PROGRAMS
STEP 1 DESULPHATION
Detects sulphated batteries. Pulsing current and voltage, removes sulphates 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 charging a defective bat-
tery.
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 cannot hold charge may need
to be replaced.
STEP 6 RECOND
Choose the Ca/Ca program to add the recondition step to the charging program.
This step can also be selected separately by choosing the BOOST-program. During
the recondition step voltage increases to create controlled gassing in the battery.
Gassing mixes the battery acid and gives back energy to the battery.
STEP 7 FLOAT
This step maintains the battery voltage by providing a constant voltage charge. This
step can also be selected separately by choosing the SUPPLY-program where it is
possible to select different voltage settings. Follow battery manufacturers recom-
mendation.
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.
