Product Overview
4 amp - 9 step Automatic smart charger - Stage 1 - Diagnosis: Analyze if the battery can accept a charge or not, and then prevent charging from proceeding on the a defective battery; Stage2- 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-Recond: 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 3 to stage 6.
