4-stage charging:
Bulk
Entered when charger is started. Constant current is applied until nominal battery voltage is reached, depending on temperature and input
voltage, after which constant power is applied up to the point where excessive gassing is starting (14.4V resp. 28.8V, temperature-
compensated).
Battery Safe
The applied voltage to the battery is raised gradually until the set Absorption voltage is reached. The Battery Safe Mode is part of the
calculated absorption time.
Absorption
The absorption period is dependent on the bulk period. The maximum absorption time is the set Maximum Absorption time.
Float
Float voltage is applied to keep the battery fully charged
Storage
After one day of float charge the output voltage is reduced to storage level. This is 13,2V resp. 26,4V (for 12V and 24V charger). This will
limit water loss to a minimum when the battery is stored for the winter season.
After an adjustable time (default = 7 days) the charger will enter Repeated Absorption mode for an adjustable time (default = one hour) to 'refresh'
the battery.
