4-stage charging:
Bulk-mode: Entered when charger is started. Constant current is applied until the gassing voltage is reached (14.4V
resp. 28.8V, temperature compensated).
Battery Safe Mode: If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen, the Multi Compact / MultiPlus Compact will prevent damage due to excessive
gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached.
The Battery Safe Mode is part of the calculated absorption time.
Absorption-mode: A constant voltage period to fully charge the battery. The absorption time is equal to 20x bulk time
or the set maximum absorption time, whichever comes first.
Float-mode: Float voltage is applied to keep the battery fully charged and to protect it against self-discharge.
Reduced Float: After one day of Float charge a reduced Float charge is applied. 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 = 1 hour).
