Memory-function
The charger will return to the last charging mode when disconnected and reconnected. If this mode is
not compatible with the connected battery, the charger will automatically return to Standby-mode.
Defective Battery Detection And Recovery
Even if the battery voltage is very low, the charger tries to rescue the battery. If the battery voltage is
between 14V to 21V it is not clear whether a fully charged 12V battery or a deep-discharged 24V battery
is connected. The charging process automatically commences with a gentle impulse charge, trying to
reactivate a 24V battery until the voltage rises. This way, even batteries believed dead can be made
reusable. If voltage doesn´t rise over 21 within 2 hours, the "Defective-Battery"-symbol lights up and the
connected battery is considered as defect.
Zero-Volt-Battery-Charging
This function is used in lithium batteries. As lithium battery packs have Protection Circuit Modules
(PCM), the Output voltage is 0V when the PCM has activated. A very small pulse current is used to
sense the connection of the battery.
Maintenance / Trickle charging
After the battery has been fully charged, the charger automatically changes to trickle charging.
Depending on the measured voltage, the charging process is interrupted or the battery is maintained in
a fully charged condition with low charging currents. A battery can remain permanently connected to the
charger without damage or adverse effect on its performance. The trickle charge can be used to maintain
a battery.
Overheat-Protection
If the charger becomes too hot during charging, the power output is automatically reduced in order to
protect the device from damage.
The IBC battery charger will NOT start charging, without a charging mode being
selected.
1. Before charging the battery, connect the output terminals of the charger to the battery. Make sure all
connections are tight and clean.
2. Make sure to choose the correct charging mode by pressing the Mode-button. A faulty selecting can
cause problems and damages to your battery and car. Please see also your car´s manual for
determining the right mode.
3. Settings are made by pressing the "MODE-button" and stepping forward by pressing the button one
step at a time, releasing the button when the required mode is reached. After a short amount of time
the charging process begins.
