The battery plays an important role in the use of the car. If it cannot supply power normally, problems will occur in the engine and circuit system of the car. Therefore, car owners usually take good care of them to avoid the dilemma of the engine not starting or the car suddenly stalling midway. In fact, car owners only need a minute or two to service the battery every time they check the engine.
Here are some tips for battery maintenance:
1. Use a damp cloth to wipe the exterior of the battery and clean the panel and battery heads (i.e. the positive and negative poles). ) Wipe off dust, oil, white powder and other dirt that can easily cause leakage. If the battery is frequently scrubbed in this manner, white acid-etched powder will not accumulates on the battery cell head and its life will be longer.
2. Open the battery water filler cap and check if the water level is at the normal position. Generally, there will be upper and lower limit marks on the side of the battery for your reference. If it turns out that the water level is below the lower mark, distilled water should be added. If distilled water cannot be obtained immediately, filtered tap water can be used in an emergency. Don't add too much water, the standard is to add some in the middle of the top and bottom markings.
3. Check if the battery charges normally. If you have an ammeter, after starting the engine, measure the voltage at both poles of the battery. It must exceed 13V to be considered normal. If you find that the charging voltage is too low, you should have a professional check the system.th load. If there is no three-function ammeter, you can carry out a visual inspection: after starting the engine, open the battery water filler cap and see if there are any bubbles in it. every little cell. The normal situation is that bubbles will continue to come out of the water, and the more oil comes out, the more oil will bubble; If you see no bubbles, there is probably a problem with the charging system. Particular attention should be paid to the fact that hydrogen will be generated during this inspection, so do not smoke during the inspection to avoid the risk of explosion and fire.
