Charging Processes:
De-Sulphation:
In this stage rising voltage and high current pulses are applied to the battery to recover
sulphated batteries.
De-sulphation current control: 25% of Bulk current delivered.
Soft-Start:
In this stage rising voltage and a maximum of 50% of bulk stage current is applied to
the battery to begin the charging process.
Bulk Charge:
In this stage rising voltage and maximum user defined current is applied to the battery.
• 5~100Amp adjustable for the HDBM150
• 1~35Amp adjustable for the HDBM35
Absorption:
In this stage a constant voltage and tapering current is applied to the battery to ensure
it reaches 80% state of charge.
Absorption stage voltages for each battery chemistry:
GEL Battery
AGM Battery
EFB Battery
WET/Flooded Battery
LiFePO

x2 for 24V mode (HDBM35 only)
Analysis:
In this stage the charger tests the battery again in order to detect bad cells and high
levels of sulphation (only for Lead-Acid batteries).
Equalization:
In this stage a higher voltage and low current is applied in order to balance the internal
cells of the battery (only for Lead-Acid batteries).
