CHARGE PROCESS
While the charge is in progress the following parameters are
continuously displayed in sequence:
• Battery voltage/cell (Output voltage) (U) (Volt);
• Charge current (Output current) (A) (Ampere);
• Capacity charged (C) (Ah);
• Eective time of charge (h) (Hours);
The letter after the value (U-A-C-h) indicates which parameter
being is displayed.
To display the time the charger uses this format:
(HOURS) . (MINUTE DECADES) h
Examples:
Time of charge 3h 30minutes: Displayed 3.3h
Time of charge 7h 50minutes: Displayed 7.5h
• The charge current follows the Wa curve as described in the norm DIN 41774.

Voltage
Initial Current
(about 16% of battery capacity)
Voltage = 2.40 V/cell
Current = 50% of Initial current
Voltage = 2.00 V/cell

Time
When the battery reaches the gassing voltage the charge continues for one half of the time
needed to reach the gassing voltage with a minimum total time of 30 minutes.
SAFETY TIMER – EMERGENCY STOP
• If the battery doesn’t reach the gassing voltage within 12 hours, the charge is terminated by
the Emergency timer. The display will show the error message “Time Error”:
