(1) Always keep the outside of the battery clean and dry, and the positive and negative poles are in good contact with the cable connector. (2) Most maintenance-free battery covers are equipped with a power indicator, which indicates the charge level of the battery in green, black and yellow. The black light indicates that the storage power is insufficient. The battery should be removed from the vehicle for supplementary charging. The yellow light indicates that the electrolyte level is too low. Check whether the battery case is cracked or damaged, and whether the electrolyte leaks. (3) The vehicle should check the liquid level every year or every 30,000 kilometers. If the liquid level is lowered, distilled water should be added according to the manufacturer's regulations. (4) When installing the car with the negative grounding iron, first connect the positive electrode column, then connect the negative electrode column, and when it is removed, it is opposite to the above method. (5) When entering the winter, measure the electrolyte density to determine the state of charge. If it is not convenient to measure the density, the load voltage can be measured to determine the state of charge. (6) When charging, the positive pole of the charger is connected to the positive pole of the battery.
