AUTOMATIC CHARGE STAGE
Stage 1 - Diagnosis: Analyse if the battery can accept a charge or not, and then prevent charging from proceeding on the a
defective battery;
Stage 2 - Desulphation: The charger can rescue most drained batteries with voltages up to a Min 1.5±0.5V
Stage 3 - Pre-charge: If the battery voltage is less than 12V, charge it at the smaller current, which will protect the battery better;
Stage 4 - Soft start: Charge the battery to the maximum current gradually and never suddenly.
Stage 5 - CC1/CC2/CC3 (Constant Current): The charger automatically adjusts the current according to the battery status in
constant current, which benefits the battery for a long life;
Stage 6- CV (Constant Voltage): The battery is charged to nearly full, and will top off at 14.6V DC;
Stage 7 - Resting: The charger will cut off with full charged statement, and achieves the high energy efficiency;
Stage 8 - Recondition: When it is fully charged and low to 12.8V within 2min, the charger will judge automatically.
Stage 9 - Restoring: The charger monitors a fully charged battery automatically. If the battery falls below 12.8V DC, the charger
will restart from stage 4 to stage 7.
