Start charging
The charger starts charging the battery with constant current up to
14.4 V (at 25 °C). The charge voltage is then held constant at 14.4 V
and the charging current is reduced until it is below a definied level.
The charge voltage then drops to 13.8 V, when the long-term charging
phase starts. During charging, battery charge is shown by the number
of LEDs illuminated. The blinking segment above these LEDs indicates
active charging. During the charge retention process, all 5 LED segments
remain illuminated and pulse at a slow rate. If the measured battery vol-
tage is below 2.0 V, the charger will enter error mode, and the warning
triangle above the battery indication will start to flash.
1. Connect mains cable to charger and plug into mains.
2. Charger in open circuit – Triangle lights up and the red triangle
flashes, because no connected battery is detected.
3. If using the vehicle power supply, switch off ignition and all other
devices consuming power.
4. Connect charging cable (red) to positive pole (+) on battery.
5. Connect charging cable (black) to negative pole (-) on battery.
Charging the battery
WARNING!
Risk of serious injury and damage from incor-
rectly connected charging terminals. Connect charging
terminals to correct poles and ensure proper electrical
connection to battery terminals.
CAUTION!
Risk of damage when attempting to charge a
faulty battery, or if using the incorrect charging voltage.
Before beginning charging, ensure that the battery to be
charged is fully functional and the charging voltage of the
charger matches the battery voltage.
