    Battery capacity Charging time
    5A 10A 20A
    20Ah 3h~5h 2h~3h 1h~2h
    36Ah 6h~8h 4h~5h 2h~3h
    60Ah 8h~10h 6h~7h 3h~4h
    80Ah 12h~15h 8h~9h 4h~5h

    160Ah ≥22h 13h~15h 8h~12h
    200Ah ≥22h ≥18h ≥14h

    Note: The above data is the actual reference charging time for battery under the normal state. For the vulcanized battery with large internal resistance, the charging time is not as the reference standard.

    Tips: Notices for battery charging

    1. When charging the automotive battery, it's best to remove the battery from the vehicle frame, and keep it away from heat and fire. Because it is easy to produce flammable and explosive gas during the battery charging process. If there is any careless operation, it is easy to cause an explosion occurred.
    2. The battery level should be checked for the water battery, because supplementing the electricity can easily damage the water battery, when the battery liquid level is too low. In addition, the six covers of the water battery must be removed during the charging process, which is good to the exhaust of the battery.

    How to use the charger?
    When the charger is plugged into the power source for the first time, will it start charging immediately, or do I need to press a button to start charging?
