7.4.1
Standard charging programs
▪
12V STD (A): Charging program for lead acid batteries (wet, Ca/Ca, EFB batteries) and
gel batteries. When the charger is used for the first time, 12V STD will appear in the
display.
▪
12V AGM (B): Charging program for AGM batteries Press the "Mode" button to switch
from the 12V STD to the 12V AGM charging program.
7.4.2
Special charging programs
▪
Winter (C): The recommended charging program for cold weather conditions (ambient
temperature of -20°C to +5°C) for normal lead acid batteries (wet / Ca/Ca batteries). Press
the "Mode" button to switch from the 12V AGM to the "Winter" charging program
▪
12V M (D): Charging program for batteries with a low capacity and for trickle charging of
all batteries listed before. Press the "Mode" button to switch from the "Winter" to the "12 M"
charging program
▪
RECOND (F): Charging program with higher end of-charge voltage and constant current
charging, used only for restoring the charging capability of lead acid batteries which have
undergone exhaustive discharge. The RECOND process must be checked every half an
hour and must never exceed a time of 4 hours. Refer to the instructions supplied by the
battery manufacturer. To go to this program, the "mode" button must be pressed for 5
seconds. To get back to the 12V STD program from the RECOND program or the supply
function, also press the "Mode" button for 5 seconds.
WARNING: gassing generates explosive gas-risk of explosion! Ensure there
is good ventilation.
Only use the RECOND program for lead acid batteries and only as described below. Take
care to avoid spilling any battery acid. Battery acid is aggressive. Read and observe the safety
information. Never use for a battery which is of sealed design (VRLA battery such as, e.g.
AGM or GEL battery). Refer to the instructions supplied by the battery manufacturer. Only use
for batteries which are free-standing and have been taken out of the car, not while installed in
your car with a connection to the car's electrical system. The higher charging voltage could
damage the electrical system. Refer to and observe the operating manual for your car and/or
contact the manufacturer of your car.
7.4.3
Additional function
▪
SUPPLY (H): For supplying 12V d.c. voltage, e.g. when changing a battery or for
operating 12V d.c. consumers. Press the "Mode" button to switch from the RECOND to
the SUPPLY function.

i.
Connect the charger to a lead acid battery as described in
section 7.5 and check the charging process every half hour.
ii.
After 4 hours at the latest or as soon as the battery starts
audibly gassing (bubbling), remove the charger as described in
section 7.5.
iii.
If possible, check the acid level and, if possible, top up the
battery cells, if necessary just with distilled water. The acid level
should ideally be between the marked max. and min. level and
should be identical for all the cells. Screw the battery stoppers,
if there are any, tightly in place.
