CTEK MXS 10 - Battery Charger Manual

This charger is included in a series of professional chargers from CTEK SWEDEN AB and represents the latest technology in battery charging.

OVERVIEW

*Supply plugs may differ to suit your wall socket.

1. Attach the temperature sensor to the charger.
2. Attach the temperature sensor to the clamp.

CHARGING

1. Connect the charger to 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 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 8-step display through the charging process.
   The battery is ready to start the engine when STEP 4 is lit.
   The battery is fully charged when STEP 7 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
	20–300Ah	Normal battery program 14.4V/10A. Use for WET batteries, Ca/Ca, MF and for most GEL batteries	-20°C–+50°C (-4ºF–122ºF)
AGM	20–300Ah	AGM battery program 14.7V/10A Use for AGM batteries.	-20°C–+50°C (-4ºF–122ºF)
RECOND	20–300Ah	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.	-20°C–+50°C (-4ºF–122ºF)
SUPPLY	20–300Ah	Supply program 13.6V/10A Use as 12V power supply or use for float maintenance charging when 100% capacity of the battery is required. Supply program activates step 7 without time or voltage limitation.	-20°C–+50°C (-4ºF–122ºF)

The spark protection on the battery charger is disabled during SUPPLY program.

*Supply program is not time or voltage limited.

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.

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.

TEMPERATURE SENSOR

The MXS 10 is equipped with an external temperature sensor. The temperature sensor is attachable. If so, the charger will compensate voltage according to ambient temperature. Activated temperature sensor will be indicated by a lit temperature sensor indicator lamp.

READY TO USE

The table shows the estimated time for empty battery to 80% charge

CONNECT THE CHARGER TO A BATTERY

INFO
If the battery clamps are incorrectly connected, 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 positively earthed batteries.

1. Connect the black clamp to the battery'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.

*) 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 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.
• 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.
