Introduction
To enjoy your new battery charger as long as possible,
please read carefully the Operating Instructions and the
enclosed safety instructions before putting it into operation.
Further, it is recommended to keep this manual for future
reference – when features of this product are required to
be recalled. Because of the continuous development of our
products, we reserve the right to make technical changes.
This document represents the original Operating
Instructions.
Appliance description
The automatic battery charger is controlled by a micro
processor and as a consequence, charging takes place in
three levels. At the first level, the battery is charged by
almost constant current to approximately 85%. At the
second level, the battery is charged to approximately 95%
at constant voltage. The third level keeps constant voltage
of the battery, i.e. the battery is constantly charged to the
full extent.

GAB 15A operating elements (pic. B)
1.
Voltage indication LED
(LED is on when the appliance is in the standby
mode or if the 2/8/10/15A button has been
pressed)
2.
2/8/10/15A charging current setting button
(One second after pressing, the appliance starts
to be charged by appropriate charging current
with the existing value being shown on the
display)
3. ON/OFF
button
(Keep the button pressed for at least 1 second –
this will switch the appliance on and “000“ will be
blinking on the display – now you are in the
standby mode)
4.
12V DC outlet button
ON/OFF with signalling by LED
(Pressing the button in the standby mode
activates the 12V DC outlet on the back of the
appliance. If the button is pressed again, the
charger gets back to the standby mode).
5.
Button for current battery voltage
(After pressing the button, the appliance shows
the current battery voltage for 3 seconds in the
standby mode and during the charging process.)
6.
"Battery fully charged" LED
7.
"Battery charging" LED
8. "Failure"
LED
9.
Three-digit LED display
(see the table for description)

Description Failure
removal
Standby mode
Check the battery
Battery voltage is
shown during the
charging process or
in the standby
mode, e.g. 13.8 V
1. Charging current
is shown (e.g. 5.8 A
);
2. Extraction flow at
12V DC outlet is
shown.
1. Battery pole not
connected
2. Short circuit
1. Connect the
battery pole.
2. Faulty battery
Exchange of
connections
(reversal of polarity)
Switch the
appliance off and
disconnect the
plug from the
outlet and connect
correctly
1. Battery is
significantly
discharged
2. Faulty battery cell
3. 3.6 V battery is
connected
Switch off and
disconnect from
the electric power
supply and
remove the battery
(faulty)
1. Battery cell short
circuit
2. Inappropriate
charging current has
been selected
Try another
charging current, if
the failure
persists, the
battery is probably
faulty
Battery terminal has
got released, the
appliance is
switching off and
activating the
warning signal
Check the
connection and
select the
charging current
again
Battery is fully
charged, battery
voltage remains
constant, battery
remains charged.
