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 7V to 10.5V it is not clear whether a fully charged 6V battery or a deep-discharged 12V battery
is connected. The charging process automatically commences with a gentle impulse charge, trying to
reactivate a 12V battery until the voltage rises. This way, even batteries believed dead can be made
reusable. If voltage doesn´t rise over 10.5V 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.
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 that choice the charger
should start the charging process.
Stopping the Charging Process
Charging can be stopped at any time by disconnecting the supply cord.
After Charging
WARNING! Disconnect the supply before making or breaking the connections to the
battery. As the released gas is flammable, avoid naked flames, glowing or electrostatically
charged material and sparks in the vicinity of the battery. Always provide adequate
ventilation. Because of this risk of explosive gas, only connect and disconnect the battery
leads when the mains supply is disconnected.
1. Unplug charger from the mains supply
2. Disconnect the negative charging lead (BLACK) from the negative post of the battery
(marked -) or mass.
3. Disconnect the positive charging lead (RED) from the positive terminal post of the battery
(marked +).
4. Clean and store battery charger.
If the charged battery is maintainable, wait some time until the bubbling stops. Inspect the liquid in each
cell again and top up carefully with de-ionized or distilled water if necessary. Now replace the caps. Any
surplus fluid around the cell tops should be wiped off carefully as it may be acidic. Avoid getting
electrolyte on your skin or clothes. Use eye protection. Wash your hands carefully.
