4.2 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.
- 5~150Amp adjustable for the SF150
- 1-35Amp adjustable for the SF35
Analysis-1:
In this stage the charger tests the battery in order to detect bad cells (only for Lead acid batteries). For abnormal cell detection
results please refer to the troubleshooting section (8).
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
Flooded Battery
LiFePO4

x2 for 24V mode (SF35 only)
Analysis- 2: In this stage the charger tests the battery again in order to detect bad cells and high levels of sulphation (only
