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);
• Effective 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.
Current
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”:
