[4] MODE 2 (14,4V/4A; >14Ah)
This mode is suitable for charging batteries with capacities larger
than 14Ah. To charge the battery, connect the charger's output cable to
the battery, ensuring the correct polarity, and then press the mode
button twice to select this mode. The corresponding LED (>14Ah) will
light up and after a short delay, if no further action is carried out, the
electronic switch will start the charging cycle with a 4A current. If
there are no errors, the LED (CHARGE) will stay illuminated for the
entire charging cycle until the battery is charged to 14,4V. When the
battery is fully charged, the LED (FULL) will light up. A trickle charge
then ensures that the battery is kept properly charged.
[5] MODE 3 (14,7V/4A; COLD)
This mode is suitable for charging batteries with capacities larger
than 14Ah in cold ambient conditions, or charging batteries wich
require a high charge voltage. To charge the battery, connect the
charger's output cable to the battery, ensuring the correct
polarity, and then press the mode button three times to select
this mode. The corresponding LED (>14Ah) and the LED (COLD)
will light up and after a short delay, if no further action is carried
out, the electronic switch will start the charging cycle with a 4A
current. If there are no errors, the LED (CHARGE) and the LED (COLD)
will stay illuminated for the entire charging cycle until the battery is
charged to 14,7V. When the battery is fully charged, the LED (FULL) will
light up. A trickle charge then ensures that the battery is kept properly
charged.
