SAFETY
• The charger is designed for lead-acid batteries from 30–500Ah. 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.
If the battery leads have been connected incorrectly, the reverse polarity protection system will
ensure that neither the charger nor the battery are damaged.
Start charging
1. Connect the charger´s AC cord to the power outlet. The charger will indicate POWER, yellow
indication lamp (B).
2. The lamp for completely discharged battery (1) will illuminate if the battery’s voltage is less
than 12V.
3. Normal charging will be indicated by the following lights: completely discharged battery (1),
bulk charging (2), absorption charging (3) or maintenance charging (4). When the maintenance
charging lamp illuminates the battery is fully charged. Charging will start if the voltage drops.
The charger can normally be connected for months. Reconditioning is indicated by the lamp (5)
illuminating.
4. If the battery leads have been connected incorrectly, the reverse polarity protection system
will ensure that neither the charger nor the battery are damaged.
5. If nothing happens. If the lamp indicating the setting and the power lamp remain lit but no
other lamp illuminates, the connection to the battery or chassis may be poor or the battery may
be faulty. Another cause may be a lack of voltage in the AC Power Supply. Begin by improving
the connection between the battery and charger.
6. Charging can be stopped at any time by disconnecting the charger’s AC cord. Always disconnect the AC cord before disconnecting the battery leads. When you stop charging a battery
installed in a vehicle you should always disconnect the battery lead from the chassis before
disconnecting the other battery lead.
BATTERY TYPES AND SETTINGS
The MULTI XS 15000 can easily be set for different types of batteries or conditions. The
following recommendations should, however, only be seen as guidelines. Please consult the
battery manufacturer for further instructions.
Settings are made by pressing the “MODE-button “ and stepping forward one press at a time
until the required mode is reached, the button is then released. After about 2 seconds the
charger activates the selected mode. The selected mode is saved in a memory in the charger
and remains there even if the charger is disconnected from battery and mains.
NORMAL
NORMAL - Normal setting for wet batteries, maintenance free
and for most Gel batteries. Some Gel batteries prefer a slightly
lower charging voltage. Please consult the battery manufacturer
when in doubt.
SUPPLY
SUPPLY - The charger operates at a constant voltage. This is
the maintenance mode for applications where maximum capacity
from the battery is important, like floor sweepers and golf carts.
Note that the Spark protection function is suppressed in this
mode.
RECOND
RECOND - This mode is used to recover deep discharged
flooded batteries where you could expect a stratified acid
(high acid weight in the bottom, low on top). Check with battery
manufacturer when in doubt.
Use this mode with care, because the high voltage will cause
some water loss. 16V is normally no problem for electronics in
12V system. Consult your supplier when in doubt. Life of light
bulbs will be reduced at higher voltage. Try to disconnect light
from the battery during this phase. Maximum effect and minimum
risk for electronics is achieved by charging a disconnected
battery.
CHARGING
Connecting the charger to a battery fitted in a vehicle
1. The power cord should be disconnected when connecting or disconnecting the battery leads.
2. Identify the battery terminal that is grounded (connected to the chassis). The negative
terminal is normally the grounded post.
3. Charging a negatively grounded battery. Connect the red cable to the positive terminal on the
battery and the black cable to good metal engine ground away from the battery. Ensure you do
not connect the black cable to fuel lines or sheet-metal body parts.
4. Charging a positively grounded battery. Connect the black cable to the negative terminal on
the battery and the red cable to good metal engine ground away from the battery. Ensure you
do not connect the black cable to fuel lines or sheet-metal body parts.
Connecting the charger to an out of vehicle battery:
1. The power cord should be disconnected when connecting or disconnecting the battery leads.
2. Connect the red cable to the positive terminal on the battery and the black cable to the
negative terminal.
CHARGING PHASES
MULTI XS 15000 charges and analyses in eight fully automatic steps and has three different
operating modes, see Battery Types and Settings.
INDICATORS
The battery charger has an 8-step fully automatic charging cycle:
Desulphation
Desulphation with pulses recovers sulphated batteries. Indicates with lamp 1.
Soft start (Lamp 1)
Start mode for the charging cycle. The charging current is limited. The start phase continues
until the battery’s terminal voltage has risen above the set limit, at which point the charger
switches to bulk charging. If the terminal voltage has not passed the voltage limit within the
time limit, the charger switches to fault mode (lamp 0) and discontinues the charging. If so, the
battery is faulty or its capacity is too large.
Bulk (Lamp 2)
Main charge when 80% of charging takes place. The charger delivers maximum current until the
terminal voltage has risen to the set level. Bulk has a maximum time, at which point the charger
automatically switches to Absorption.
Absorption (Lamp 3)
Complete charge up to virtually 100%. The terminal voltage is maintained at the set level.
During this phase the current tapers successively. Once the current has tapered to the set limit,
this phase switches to being timed. If the total time for Absorption exceeds the time limit the
charger automatically switches to maintenance.
Analysis (Lamp 3)
Testing self-discharge. If self-discharge is too high, charging is discontinued and fault mode is
indicated.
Maintenance charging - Float (Lamp 4)
Charging at constant voltage.
Maintenance charging - Pulse (Lamp 4)
Charging varies between 95% and 100% state of charge. The battery receives a pulse when the
voltage drops and keeps the battery in perfect condition when it is not in use. The charger can
be connected for months at a time. The charger continuously measures the terminal voltage
to determine whether a charging pulse should be initiated. If the battery is loaded and/or the
battery’s terminal voltage drops the charger starts a charging pulse until the terminal voltage
reaches the set level. The charging pulse is then discontinued and the cycle is repeated
infinitely. If the terminal voltage drops below a lower limit, the charger automatically goes back
to the beginning of the charging curve.
Recond (Lamp 5)
This mode is used to recover deeply discharged flooded batteries. Recondition of deep
discharged batteries. The voltage increases with reduced current for a limited time period. The
higher voltage starts some gassing and mixing of the acid, which is beneficial for both battery
capacity and expected life. Note that the battery could emit explosive gas during Recond.
Recond is performed between Analysis and Maintenance.

self-discharge is too high.
TEMPERATURE COMPENSATION
MULTI XS 15000 has a sensor cable placed together with the battery cables. The units will
automatically adjust the charging voltage if the temperature deviates from +25°C. A high
temperature lowers the voltage and freezing conditions is handled by higher voltage.
The temperature is best measured on or very close to the battery. Therefore always place the
sensor as close to the battery as possible when charging. The sensor cable could be prolonged
or cut to length with the same functionality. A short-circuited or disconnected sensor is indicated
by lamp A. The charging voltage is then adjusted to the +25°C condition.

*) Back current drain is the current that the charger drains from the battery if the AC cord is
disconnected.
**) The quality of the charging 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. The battery chargers from CTEK produces very high quality
voltage and current with low ripple.
***) IP 44 cannot be guaranteed if the charger is not positioned horizontally with the long side
or top side turned up.
MAINTENANCE
The charger is maintenance-free. The charger must not be opened; doing so will invalidate
the warranty. If the power cable is damaged it must be replaced by CTEK or its authorized
representative. The charger casing can be cleaned using a damp cloth and mild cleaning agent.
Remove the plug from the power socket before cleaning.
