To stop charging the battery. In the following order, cut off the
power supply, remove the clamp from the bodywork or the
negative (-) terminal, and remove the clamp from the positive
(+) terminal.

Charging a battery
¾ Connect the red clamp (+) to the battery’s positive pole
and the black clamp (-) to the battery’s negative pole.
The battery charger sets in ”Test” mode, ignore this step
and proceed as follows.
¾ Plug the plug into the socket to begin charging.
L The “D” LED (red) lights up whenever the clamps have
been connected to the battery with reverse polarity. Invert
the connection.
¾ Use the “Set” key to select the charging program desired
for the battery Fig.2.
L
14.7 Volt charging
Option for AGM Power batteries that require a higher voltage.
Some battery manufacturer suggest using this program for
batteries that run at temperatures of less than 5°C.
EQUALIZATION (“E75%” LED will be
ashing)
Option to equalize the acid concentration between the
elements of the battery. In this way the average life of the
battery increases.
This option can only be applied to WET batteries because
they withstand overvoltage in a better way.
SUPPLY at constant 12,0 Volt (“E” LEDs
will illuminate in sequence)
Charging is performed with constant voltage at 13.5V.
If the absorbed current is too high, the output voltage will
drop.
L In this operating mode, the anti-spark and Reverse
Polarity functions are disabled.
L The battery charger cannot begin charging when a 12V
battery delivers a voltage of less than 2V (battery extremely
discharged). Use Charging Program “SUPPLY” to give a
brief charge to the battery.
Charging phase Fig.2
Phase 1
A pulsed charge is performed, this helps removing the
sulphated particles from the lead plates of the battery (led
“E0%” will be ashing).
Phase 2
The charger has a limited output current until the battery will
be in a condition to accept the standard charging current (led
“E0%” permanently illuminated).
Phase 3
The charger will deliver the rated current until the battery has
reached its 80% capacity (led “E 25%”; “E50%” permanently
illuminated).
Phase 4
Constant voltage charge to bring the battery at its full capacity
(led “E75%” permanently illuminated).
Phase 5
The charger checks the capability of the battery to “hold the
charge” (led “E75%” permanently illuminated).
Phase 6
Initial phase of the equalization program (led “E75%” will be
ashing).
Phase 7
FLOATING maintenance (for 7 days): during this period
of time the battery is kept ready to deliver its maximum
performance (led “E100%” will be ashing).
Phase 8
PULSED maintenance: the charger is continuously checking
the battery voltage and when necessary will deliver a pulse
of current to maintain the battery capacity at 95 - 100% (led
“E100%” permanently illuminated) .
Charging Errors
Led “C” will indicate some possible malfunctioning of the
battery all along the charging cycle.
Led “C”+”E0%” ashing = sulphated battery, a battery
replacement may be necessary.
Led “C”+”E0%” permanently illuminated = the battery
does not accept the charge, a battery replacement may
be necessary.
Led “C”+”E 25%” permanently illuminated = the capacity
of the battery is too large for the charger, or the battery has
a short-circuited cell.
Led “C”+”E0%” permanently illuminated = the battery
cannot “hold the charge”, a battery replacement may be
necessary.
Led “C”+”E75%” permanently illuminated = the current
is not owing through the battery, the battery might have a
short-circuited cell.
L If the power supply fails, the charging desired will
automatically resume when power returns.
L The battery charger is equipped with thermal protection
that gradually reduces the output current whenever the
internal temperature becomes too high.
Never leave the battery unattended for long periods
of time.
