Equalization Charge:
It is only applicable to Lead Acid based battery especially wet type.
It reconditions the deeply discharged battery and reduces stratification, counter
sulfation found in deeply discharged and infrequent used battery. It also gives
battery cells a well balanced charge.
Once set, the charging algorithm is automatic. The charger will go through Soft
Bulk (for deeply discharged battery) -> Bulk -> Absorption ->
Equalization ->
Float charge stages.
You can exit from Equalization charge to Float anytime by long press at the
SET button.
Sleep Mode & Half Power Mode
Both charge mode have only 20Amp maximum charging current in stead of
40Amp.
The cooling fan will be off all the time to ensure total silence of a quiet charging
operation.
Half Power mode is more suitable for batteries with less than 135Ah capacity.
The sleep Mode has an 8 hour timer, charger will go back to normal maximum
output of 40Amp
Battery with Loads connected such as in caravan, campers & etc.
The charger can be used as a stand alone automotive charger or connected to
battery all the time with and without load as long as the load is not more than
30Amp in normal mode or 15Amp in half power /sleep mode.
Lead Acid based batteries: LEAD / AGM
