CTEK XS 800 User manual

INTRODUCTION
CTEK XS 800 is a switch mode charger with pulse maintenance and is a part of a series of professional
battery chargers from CTEK SWEDEN AB. These chargers represent the latest technology within battery
charging. A CTEK XS 800 gives the battery maximum life. Read this User’s Manual and follow the
instructions carefully before you start to use the charger.
SAFETY
• The charger is designed to charge 12 V lead-acid batteries from 1.2 to 32 Ah. However, the charger can
maintain batteries up to 60 Ah. Do not use the charger for any other purpose.
• Wear protective glasses and turn your face away when connecting or disconnecting the battery!
• It is important to avoid sparks in the immediate vicinity as the battery can give off explosion gases during
charging.
• Battery acid is corrosive. If the acid comes into contact with the skin or eyes, rinse immediately with plenty
of water and contact a doctor at once.
• Provide good ventilation when charging.
• The charger should not be covered.
• Do not put the charger on the battery when charging.
• Never charge a frozen battery.
• Mounting only allowed on a plane surface.
• Children must not use the battery charger, except under the supervision of an adult.
• The battery charger may only be used if you have read and understood the manual.
• The appliance is not intended for use by inrm persons without supervison.
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 XS 800 is suitable for charging all types of 12 V lead-acid batteries: open batteries, MF, AGM and
most GEL-batteries. Battery sizes from 1.2 to 32 Ah. The charger can maintain batteries up to 60 Ah.
CHARGING
Connecting the charger to a battery tted in a vehicle:
1. The power cord should be disconnected when the battery leads are connected or disconnected.
2. Identify the pole that is grounded (connected to the chassis). The negative terminal is normally the
grounded pole.
3. Charging a negative grounded battery. Connect the red cable to the positive pole on the battery and the
black cable to the vehicle’s chassis. Ensure you do not connect the black cable close to the fuel pipe or the
battery.
4. Charging a positive grounded battery. Connect the black cable to the negative pole on the battery and
the red cable to the vehicle’s chassis. Ensure you do not connect the red cable close to the fuel pipe or the
battery.
Connecting the charger to a battery that is not tted in a vehicle:
1. The power cord should be disconnected when the battery leads are connected or disconnected.
2. Connect the red cable to the positive pole on the battery and the black cable to the negative pole.
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 battery tted in a vehicle you
should always disconnect the battery lead from the chassis before you disconnect the other battery lead.
5. If the charging lamp and maintenance charging lamp alternately ash the reason for this is the following:
• If the lamps ash a few times per second then the battery is probably sulphated. If the lamp ashes more
than 60 minutes the battery should be replaced.
• If the ashing occurs with a few minutes’ interval then the battery has a high self-discharge and may need
to be replaced..

CHARGING CYCLE
CTEK XS 800 has a three 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 14.4 V. At this point the voltage will be regulated and kept constant while the charging current is succes-
sively lowered. Once the charging current has dropped below 0.4 A the charger switches to maintenance
charging.
If the battery is loaded and the battery’s terminal voltage drops to 12.9 V the charger automatically switches
back to the beginning of the three step cycle. The charger requires a reverse voltage from the battery of at
least 6 V to start the charging cycle, this means that if the battery is so deeply discharged that the terminal
voltage is lower than 6 V the charger cannot charge the battery in question. A normal discharged battery has
a terminal voltage of 10.5 V.
Charging phases:
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 charg-
ing. 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.
BULK CHARGING TIME
The table shows times for bulk charging.
THERMAL PROTECTION
CTEK XS 800 is protected from overheating. In the event of increased ambient temperature the output is
reduced.
MAINTENANCE
The charger is maintenance free. Note that dismantling the charger is not permitted and invalidates the
warranty. If the power cord becomes damaged the charger must be returned to the dealer for repair. The
case can be cleaned using a soft, damp cloth and a mild detergent. The charger should be disconnected
before cleaning.
EQUIPMENT
CTEK XS 800 is supplied with one battery lead with a battery clip and one battery lead with a ring cable lug.

*) Back current drain is the current that the charger drains the battery with, if the wall socket is disconnected.
**) The quality of the charge voltage and charging current are very important. High current ripple heats the
battery and ages the positive electrode. High voltage ripple can damage other equipment connected to
batteries. CTEK XS 800 produces very high quality voltage and current with low ripple.
