Bulk
4-stage charging:
A
Bulk: Entered when charger is started. Constant current is applied until the gassing voltage is reached (14.4V resp.
28.8V, temperature compensated).
Battery Safe: If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage
PPENDIX F: temperature compensation
has been chosen, the Multi 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 period is part of the calculated absorption time.
Absorption: 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: Float voltage is applied to keep the battery fully charged and to protect it against self-discharge.
Storage: After one day of Float charge the charger switches to storage. This is 13,2V resp. 26,4V (for 12V and 24V
charger). This will limit water loss to a minimum. After an adjustable time (default = 7 days) the charger will enter
Repeated Absorption for an adjustable time (default = 1 hour).
