USING REPAIR
This mode is for LEAD-ACID batteries only. It is an advanced battery recovery mode for
repairing old, idle, stratified or sulphated batteries.
NOT all batteries can be recovered. For optimal results, take the battery through a full
charge cycle, bringing the battery to full charge, before using this mode.
When this mode is chosen, ensure you press Mode button for choosing appropriate 12V
Mode(s) .
One REPAIR cycle can take up to eight hours to complete the recovery process and will
enter to charge (8 steps charging cycle) when completed. This mode uses a high charging
voltage and may cause some water loss in WET (flooded) cell batteries. Plus, some
batteries and electronics may be sensitive to high charging voltages. To minimize risks,
disconnect the battery from the vehicle before using this mode.
STEP 1:
DIAGNOSIS (Check if battery has connected with the charger and also check
battery voltage)
STEP 2:
DESULPHATION (If battery voltage is too low, programs automatically generate
pulsing current to remove sulphate, up to 5 hours)
STEP 3:
ANALYSE (Check if the battery voltage reaches to the threshold after
desulphation, and charging begins if the battery voltage is OK)
STEP 4:
SOFT START (Charge with echelon constant current)
STEP 5:
BULK (Charge with constant maximum current until battery voltage is reached to
the threshold)
STEP 6:
ABSORPTION (Provide gradually declining current charge for maximum battery
voltage)
STEP 7:
ANALYSE (Test if the battery can hold charge)
STEP 8:
MAINTENANCE (Continuously monitor the battery, and charging current will
intelligently adapt to the variable battery voltage).

Different battery capacity and residual voltage would affect the charging time. Following data is only
for reference (when discharge 12V lead-acid battery to 9V, with 5A discharge current; when discharge
24V lead-acid battery to 18V, with 10A discharge current).
