INTRODUCTION
Congratulations on your purchase of your new professional CTEK XC 800 Switch Mode
Charger with Pulse Maintenance. CTEK XC 800 is a member of a family of professional chargers from CTEK Sweden AB. It represents the state-of-the-art technology for battery charging.
A CTEK XC 800 will prolong the lifetime of your battery. Read this user manual and follow the
instructions carefully before using the charger.
SAFETY
• The charger is designed to charge 6V lead-acid batteries from 1.2 to 32Ah. However, the
charger can maintain batteries up to 100Ah. Do not use the charger for any other purpose.
• Use safety glasses and turn your head away when connecting or disconnecting a battery.
• Battery acid is corosive. Rinse immediately with water if acid comes into contact with skin or
eyes. Seek medical advice.
• Make sure that the cable is not being pinched or in contact with warm surfaces or sharp
edges.
• While charging, a battery can emit explosive gases, so it is important to avoid sparks in the
immediate area.
• Always provide for proper ventilation during charging.
• Avoid covering the charger.
• Make sure that the electrical cable does not come into contact with water.
• Never charge a frozen battery.
• Never charge a damaged battery.
• Do not place the charger on the battery while charging.
• The electrical connection must fulfil the national heavy current requirements.
• Check the cabling in the charger before use. Make sure there are no cracks in the cabling or
in the protective covering. A charger with damaged cables may not be used.
• Always check that the charger has gone over to maintenance charging mode before leaving
the charger unattended and connected for long periods. If the charger had not gone over
to maintenance charging within 3 days, this is an indication of a problem. In this case the
charger must be disconnected manually.
• All batteries fail sooner or later. A battery that fails during charging is normally taken care of
by the chargers advanced control, but certain uncommon errors in the battery can still arise.
Don’t leave the battery charger unattended for a longer period of time.
• Only mount the charger on a flat surface.
• This equipment may not be used by children or by those who can not read and understand
the manual if they are not supervised by a responsible person who can guarantee that the
battery charger is being used in a safe manner. Store and use the battery charger out of the
reach of children. Make sure that children do not play with the battery charger.
BATTERY TYPES
The following recommendations should only be considered as guidelines. In the event of
uncertainty always refer to the battery manufacturer’s recommendations.
CTEK XC 800 is suitable for charging all types of 6V lead-acid batteries: open batteries, MF,
AGM and most GEL-batteries. Battery sizes from 1.2 to 32Ah. The charger can maintain
batteries up to 100Ah.
CHARGING
Charging batteries mounted in a vehicle:
1. The power cord should be disconnected before connecting or disconnecting the battery
leads.
2. Identify the pole that is grounded (attached to the chassis). Ground is normally connected to
the negative terminal.
3. Charging a negatively grounded battery. Connect the red wire to the positive pole of the
battery and the black cable to the vehicle’s chassis. Be careful not to connect the black cable in
the vicinity of a fuel pipe or the battery.
4. Charging a positively grounded battery. Connect the black wire to the negative pole of the
battery and the red cable to the vehicle's chassis. Be careful not to connect the red cable in the
vicinity of a fuel pipe or the battery.
Charging of a battery not connected to a vehicle:
1. The power cord should be disconnected before connecting or disconnecting the battery
leads.
2. Connect the red wire to the positive pole of the battery and the black cable to the negative
pole.
Connecting the provided cables with eyelet terminals:
Make sure that the cable is not being pinched or in contact with warm surfaces or sharp edges.
When the cable is mounted on the battery, it should not be connected to the charger. Connect
the eyelet terminals to the battery's poles – the red cable to the positive pole and the black
cable to the negative pole. After this, the quick contact can be connected.
Reverse Polarity Protection
If the battery cables are connected incorrectly, the reverse polarity protection will make sure that
the charger and the battery are not damaged. In this case, the red warning lamp will be lit.
Start charging
1. Once you have checked that the battery leads have been connected correctly, you can start
charging by connecting the charger to the wall socket. If the battery leads have been connected
incorrectly the polarity reversing protection will ensure that neither the charger nor the battery
will be damaged. The fault indicating lamp will then come on. If this is the case, start from
point 1 under ”Connecting the charger...”
2. The charging lamp
or the maintenance charging lamp
will now come on. When the
maintenance charging lamp comes on the battery is fully charged. When the battery’s voltage
drops the charger will send a pulse to the battery. The pulse length depends on how much the
voltage has dropped. The charger can be connected for months.
3. If nothing happens. If none of the lamps come on this may be due to the connection to the
battery or chassis is poor or that the battery is faulty or has a too low terminal voltage. Another
cause may be a lack of voltage in the wall socket..
4. Charging can be stopped at any time by disconnecting the charger’s power cord. Always
disconnect the power cord before disconnecting the battery leads. When you stop charging a

CHARGING PHASES
CTEK XC 800 has a four step fully automatic charging cycle IUoUp. At the start of charging
the battery charger delivers maximum current to the battery and the battery voltage increases
constantly to a set level of 7.2V. At this point the voltage will be regulated and kept constant
while the charging current is successively lowered. Once the charging current has dropped
below 0.4A the charger switches to maintenance charging.
If the battery is loaded and the battery’s terminal voltage drops to 6.45V the charger automatically switches back to the beginning of the four step cycle. The charger requires a reverse
voltage from the battery of at least 3.7V to start the charging cycle, this means that if the battery
is so deeply discharged that the terminal voltage is lower than 3.7V the charger cannot charge
the battery in question. A normal discharged battery has a terminal voltage of 5.3V.
Charging phases:
Desulphation – Desulphation with pulsing for sulphated batteries.
Bulk – Main charge when 80% of charging takes place. The charger delivers a constant current
until the terminal voltage has risen to the set level.
Absorption – Complete charge up to virtually 100%. The terminal voltage is maintained at
the set level. During this phase the current drops successively so the terminal voltage does
not become too high. If the absorption phase has been in progress for more than 18 hours
the charger switches to maintenance charging. This function prevents damage if the battery
is faulty.
Pulse – Maintenance charging. Charging varies between 95% and 100%. The battery receives
a pulse when the voltage drops. Keeps the battery in perfect condition when it is not used. The
charger can be connected for months at a time. If possible, check the water level in the battery.
TEMPERATURE PROTECTION
CTEK XC 800 is protected from being overheated. The power will be reduced if the ambient
temperature is raised.
MAINTENANCE
The charger is maintenance free. Note that disassembly of the charger is not permitted and
will void the warranty. If the power cord is damaged, the charger must be left to the reseller for
maintenance. The case can be cleaned with a soft damp cloth and mild cleanser. The charger
should be disconnected from the power while cleaning.
EQUIPMENT
CTEK XC 800 is delivered with a set of battery leads with battery pole clamps and a set of
battery leads with eyelet terminals.

*) Back Current Drain is what the charger uses to drain the battery if the power cord is disconnected.
**) Quality of the current and voltage are very important. High current ripple heats up the
battery and makes the positive electrode age prematurely. High voltage ripple could harm other
equipment connected to the battery. CTEK XC 800 produces a high quality current and voltage
with very low ripple.
***) If the power connected is the flat European contact type, the battery charger has insulation
class IP63, except in Switzerland where IP65 is valid.
