HOW TO CHARGE

1. Connect the charger to the battery.

1 2

For batteries mounted inside a vehicle

1. Connect the charger according to the vehicles manual.

2. Connect the charger to the wall socket.

3. Disconnect the charger from the wall socket before disconnecting the battery.

2. Connect the charger to the wall socket. The power lamp will indicate that the mains cable is connected to the wall socket. The error lamp will indicate if the ring terminals

(M10) are incorrectly connected. The reverse polarity protection will ensure that the battery or charger will not be damaged.

3. 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.

4. Stop charging at any time by disconnecting the mains cable from the wall socket.

ERROR LAMP

If the error lamp is lit, check the following:

1. Is the positive ring terminal connected to the battery's positive pole?

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

MODE

3. Has charging been interrupted in or ?

Restart the charger. 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.

*) 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. PRO 25S

CHARGING STEPS

Time limit:

1

15.8V

8h

2

Max 25A until 12.6V

8h

3

Increasing voltage to

14.4V, max 25A

20h

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.

4

Declining current

14.4V

16h

5

Checks if voltage drops to 12V

3 minutes

6

13.6V

max 25A

10 days charge cycle restarts if voltage drops

7

12.9V–14.4V

20–1.2A

Charge cycle restarts if voltage drops

STEP 5 ANALYSE

Tests if the battery can hold charge. Batteries that can not hold charge may need to be replaced.

STEP 6 FLOAT

Maintaining the battery voltage at maximum level by providing a constant voltage charge.

STEP 7 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.
