Charging
General
Charging the bat-
tery
To start charging, proceed as follows:
Switch off engine and ignition, switch off all consumers.
Set the selector switch to the correct position (see "Setting the selector switch")
Establish connection to battery
Charger displays battery open circuit voltage
Connect charger to grid
Charger starts to charge
Charger displays current state of charge as a sequence of bars
Conservation
charging
The charger automatically switches to conservation charging once the battery is fully
charged. The fully charged battery symbol (4 bars) is constantly displayed during conser-
vation charging.
This allows the charger to be continuously connected to the battery without overcharging
the battery and without any additional electricity costs.
Charging a deep-
discharge battery
If there is nothing on the charger display during test mode, the battery is in deep discharge.
The charger recharges deep-discharge batteries with gentle pulses over a long period. Dis-
connect battery from vehicle power supply and consumers before charging.
Trickle charging
(Acctiva Easy chargers
only)
With trickle charging, consumer loads (e.g. car radio) may be used during the charging pro-
cess. Note that:
-
the power used over a long period is lower than the charging current
-
the charging period is longer and may therefore trigger a safety cut-out
Back-up mode
(Acctiva Easy chargers
only)
The charger powers the vehicle electronics while the battery is being changed. Any saved
data (e.g. car radio code, seat settings, etc.) are retained.
To operate the charger in back-up mode, proceed as follows:
Switch off engine and ignition, shed all loads
WARNING! Risk of explosion from short circuits and arcs. Before connecting/dis-
connecting the battery, disconnect the charger from the mains supply. During op-
eration, check that charging terminals and battery poles are properly connected.
CAUTION! Risk of damage when attempting to charge a faulty battery. Before
charging, ensure that the battery to be charged is fully functional.
