8 Stage Automatic Battery Management:

Polarity Check
Checks the battery leads have been connected correctly

Battery Analysis
Assesses battery and determines best charging method

Soft Start Charge
Controlled build-up of charge current ensuring discharged batteries are charged safely

Bulk Fast Charge
Charges at a fast rate to bring the battery to approximately 85% capacity


Lowers the charge rate and gives a topping charge to ensure the battery is charged to 100%

Voltage Check
Hourly voltage checks assess battery health

Battery Condition
LED lights indicate a week or strong battery

Maintain Mode:
Applies an appropriate charge if voltage drops outside acceptable limits to ensure the battery voltage and condition remains perfect
