CHARGING PHASES
MULTI XS 15000 charges and analyses in eight fully automatic steps and has three different
operating modes, see Battery Types and Settings.
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.

Fault mode
The charger goes to fault mode if the time for gradual start has been exceeded or if the battery’s
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.
