1. Regular charge mode:
1.1. Please make sure that the charging current (ampere) regulator [9] is set to ‘MIN’ position
and the charger and the cables are not damaged.
1.2. Connect the charger connectors to corresponding battery terminals. It is recommended to
connect the positive connector before connecting the negative. Preserve correct polarity (+
RED, - BLACK). If the battery is installed inside a vehicle disconnecting negative
(chassis/ground) clamp from the battery is advised.
1.3. Ensure that the charger connectors have been connected properly and securely. Double
check if the correct polarity is preserved. Make sure the cooling fan [11] is not covered and the
uninterrupted air flow is possible. Connect the charger to AC mains earthed socket. The device
should be used only with properly grounded power sockets.
Turn on the charger using the power switch on the back [10].
1.4. By default the charger will start in 12V charge program which is indicated by
corresponding LEDs [1,7]. If charging 24V is desired, the ‘battery type’ [5] button should be
pressed, the 24V indicator LED [6] will light up. Do not activate 24V program when connected
to a 12V battery as there is a serious risk of causing irreversible damage to the battery and/or
car equipment if connected.
1.5. The LCD [8] acts as ampere meter, it shows actual current that is being used to charge the
battery. Charging current can be increased by turning the knob [9] towards ‘MAX’ position.
It is not recommended to set values higher than 1/5 of battery’s capacity, refer to a battery
data sheet for more details.
Charging current that is visible on LCD can be lower as the value set – it is internally limited
depending on actual voltage and charge level of a battery. In case of any abnormal behavior
e.g. electrolyte boiling, the charging current should be reduced manually.
1.6. As the charge process develops the charging current starts decreasing. Typical battery can
be considered fully charged when the charging current drops to about 2A which is indicated as
‘002’ on the LCD [8]. The battery’s voltage is strictly controlled and kept stable to prevent
overcharge. However it is not advised to leave the fully charged battery connected to the
charger for a prolonged period of time, i.e. several days and more. Even safe voltage level of
14.8V / 29V can eventually lead to increased gassing and reduce the service life of a battery.
1.7. When the charging process is finished, turn off the charger using the power switch on the
back [10]. Disconnect the charger from AC mains power source, next disconnect negative
connector from the battery. Next, disconnect the positive connector.
Turn the ampere regulator knob [9] to ‘MIN’ position.
2. Notice:
2.1. In case of a AC power source break / reconnection, the charger will automatically recover
in default 12V charging mode.
2.2. In case of fatal error and overheat, the charger stops operating. The error indicator [2] will
light up.
2.3. The charger is equipped with automatic desulfation mode. The charging current will be
reduced automatically if deeply discharged battery is connected. The process can take from
few minutes to several hours. After successful recovery the charging current will increase to a
preset value.
