14.4V/0.8A
Use for smaller batteries.

Normal battery program

14. 4V/5A
Use for WET batteries, Ca/Ca,
MF, GEL batteries and many
AGM batteries.

Cold weather program

14. 7V/5A
Use for charging at low tempera­tures and for power AGM batter­ies like Optima and Odyssey.

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 discharge to
maximise lifetime and capacity.
The Recond program adds
STEP 6 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.

ERROR LAMP

If the error lamp is lit, check the following:

1. Is the chargers positive lead connected to the battery´s
positive pole?

2. Is the charger connected to a 12V battery?

3. Has charging been interrupted in STEP 1, 2 or 5?

Restart the charger by pressing the MODE-button. If charging is still
being interrupted, the battery...

STEP 1: ...is seriously sulphated and may need to be replaced.
STEP 2: ...can not accept charge and may need to be replaced.
STEP 5: ...can not keep charge and may need to be replaced.

POWER LAMP

If the power lamp is lit with a:

1. STEADY LIGHT

The mains cable is connected to the wall socket.

2. FLASHING LIGHT:

The charger has entered the energy save mode. This happens if the
charger isn´t connected to the battery in 2 minutes.

Limit:

STEP 1 DESULPHATION

Detects sulphated batteries. Pulsing current and voltage, removes sulphate from the
lead plates of the batter y restoring the batter y capacity.

STEP 2 SOFT START

Tests if the batter y 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 batter y 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 gassing in the battery. Gasing mixes the batter y 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.

CONNECT AND DISCONNECT THE CHARGER TO A BATTERY

INFO

If the batter y clamps are incor­rectly connected, the reverse
polarity protection will ensure that
the bat tery and charger are not
damaged.

For batter ies mounted inside a
vehicle

1. Connect t he red clamp to the b at­tery 's positive po le.

2. Connec t the black clamp to the
vehicl e chass is remot e from the f uel
pipe and the bat tery.

3. Connect the ch arger to t he wall
socket

4. Disconnect the charger from t he wall
socket b efore disconnecting the bat tery

5. Disco nnect t he black clamp before

–

the red clamp.

Some vehicles may have posi­tivel y eart hed batte ries.

1. Connect t he black clamp to the bat ­tery 's negative pole.

2. Connec t the red clamp to t he vehicle
chassis remot e from the f uel pipe and
the bat tery.

3. Connect the ch arger to t he wall
socket

4. Disconnect the charger from t he wall

*) 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 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 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.
