Functional Description/Charging Process - ProCharger 4.000 Mode D'emploi

deeply discharged.
• If lead batteries are stored for a longer period, re-charge them occasionally, i.e.
at least every 3 months, in order to prevent deep discharge.
• Do not smoke and always avoid naked flames, naked light and sparks in the
vicinity of batteries (risk of explosion from detonating gas).
Note – Battery data:
If you have any questions on the battery data, please contact the battery manufacturer.

Step 1 "Analysis": An analysis is performed to determine whether a battery is
connected and the battery voltage is within the valid range.
Step 2 "Check": The connected battery is checked for deep discharge and sulphation.
Step 3 "Recovery": Depending on the battery charge level and the necessity,
the battery is precharged to 7 V (if the battery voltage is lower than 7 V) and/or
desulphated. During the desulphation process, the battery is fed with a pulsating
current. This process can take up to one hour.
Step 4 "I-phase (charge voltage adjustment)": The battery is charged at a constant
current (I-phase) until the end-of-charge voltage (14.3 V/14.7 V) is reached.
Step 5 "U1-phase (charge current adjustment)": The battery voltage is held
constant and the charging current adapts to the level of charge in the battery. The
fuller the battery, the lower the charging current.
Step 6 "Test": The test draws a defined load current from the battery. If the voltage
