The specific gravity of the electrolyte drops below 1.200; the discharge in winter exceeds 25%; the discharge in summer exceeds 50%; the light is dim; the start is weak, and when the above occurs, charging is required. Some people think that fast charging can save time and only takes 3-5 hours. In fact, fast charging only activates the surface of the battery quickly, but in fact the internal battery is not fully charged. In addition to fast charging, there is also a kind of slow charging, charging time is 10-15 hours, those who are deeply deficient in the battery must be slowly charged, otherwise the charging time is not enough, the amount of charging is insufficient, which directly affects the driving performance of the car. . Although charging is a fairly simple operation, there are some caveats: 1. When charging, there should be no sparks near the battery, and smoking is prohibited. 2. Wear protective clothing when charging lead-acid batteries. 3. When charging one or more batteries in parallel, the charger voltage should not exceed 16V. 4. When turning on the charger, set the minimum current first, then gradually increase the current until the battery starts to accept current. 5. Connect the positive line of the charger to the positive pole of the battery and the negative line to the negative pole of the battery. If it is a deep discharged battery or a low temperature battery, this process may take several minutes.

What we usually call "maintenance-free battery" is not really "maintenance-free", but rather that the battery does not need to be charged under normal conditions. The maintenance-free batteries on some cars are also equipped with a temperature-compensated hydrometer that indicates the storage state of the battery and the height of the electrolyte level. When the indicator eye of the hydrometer is green, it indicates that the charging is sufficient, the battery is normal; when the indicator eye green point is little or black, it indicates that the battery needs to be charged; when the indicator eye shows light yellow, it indicates that there is a fault inside the battery, it needs to be repaired. Or replace it.
