The battery voltage is kept constant at 13.5V.
This mode is retained for approx. 2 hours.
Thereafter, the appliance switches into sleep mode.

The INTELLI 3 is in power-saver mode. If the battery
voltage of 12.7V is undershot,
the INTELLI 3 switches itself on again and starts the
charging program from the beginning.
Note:
By pressing the button, you can awaken the INTELLI
3 at any time. The current battery voltage is displayed
for 10 seconds. Then, it switches back into power-saver
mode.
Power supply
U=13.7V I=1.0A
No LED is lit
The INTELLI 3 is in power supply mode.
The voltage is approx.13.7V. The current is limited to
approx. 2.5A.
Caution: Risk of short circuit to the battery clips!
1)
Sulphate layer: A (lead-) sulphate layer is formed – in the case of lead acid batteries – on the surface of their electrode plates when the
battery is stored uncharged for a prolonged period.
(All lead batteries get discharged with time.) The reaction surface of the lead electrodes gets reduced hence => the battery capacity is
inadequate for starting. A sulphate layer can only be dissolved with a special charging mode. The thicker the sulphate layer becomes,
the more diffi cult and tedious it becomes, till it is fi nally not possible any more at all.
Crystals from the sulphate layer can fall on the battery electrodes from vibrations. A sludge layer is formed on the fl oor of the cell. If
the sludge layer becomes too high, it can cause a short circuit between the electrodes => the battery cell gets destroyed.
2)
Cell short-circuit: There is a cell of the battery that cannot output any voltage because of a short circuit and cannot take up a charge
any more either. This fault is caused by impurities and lead sludge precipitation in the cell.
