1 Density "Ning small, not big"
Some drivers believe that the higher the electrolyte density, the lower the discharge degree of the battery, the higher the terminal voltage of the battery, the greater the charging capacity, and can prevent the electrolyte from freezing in winter, and can freeze the battery to regulate electrolysis. In the liquid density, not only the density of the original electrolyte is higher than the specified value, but also the addition of distilled water in normal use is also used to add some electrolytes of different densities, resulting in higher and higher electrolyte density. In fact, this method is very wrong.
Electrolyte density is an important indicator to measure the degree of battery discharge. Based on the premise that the original electrolyte density has been determined. Adding electrolytes of different densities means only increasing the density of the original electrolyte, even the measured electrolyte density. The higher is, the lower the degree of discharge is; increasing the density of the electrolyte can increase the battery's voltage and charging capacity. In contrast, increasing the density of the electrolyte can increase the electromotive force of the battery and increase its terminal voltage and charging capacity. On the other hand, if the electrolyte density is too large, the viscosity of the electrolyte increases, and the internal resistance increases, which reduces the permeability of the electrolyte, which in turn causes the voltage and charge capacity of the battery to decrease, and the density of the electrolyte is too large, which may cause The plates are vulcanized and cause various problems, such as corrosion of the separator, which shortens battery life.

  1. Ignore the inspection of electrolyte
    The battery electrolyte level should be checked regularly. If the electrolyte is insufficient, the upper plate will be vulcanized in contact with the air, which will reduce the charging capacity of the battery and shorten its service life. Usually, it is checked for half a month in winter. In summer, high temperature water evaporates easily and should be checked once a week. The liquid level of the electrolyte is usually 10mm-15mm higher than the plate protection net. The lower limit is marked, so the electrolyte level should be within the specified range. Although it is not necessary to add distilled water during use, it should be checked during the daily maintenance of the vehicle to check the electrolyte level. If it does not meet the requirements, it should be adjusted.

  2. The electrolyte level is "condensed high not low"
    Some drivers often use the wrong method of "higher than lower" when filling the battery with electrolyte or adding distilled water. The electrolyte level is too high. During the driving of the vehicle, the electrolyte can easily leak from the ventilation holes and corrode the pole, resulting in poor contact or early damage to the pole. The electrolyte accumulated on the battery cover connects the positive and negative columns to form a circuit, thereby discharging the battery itself. At the same time, the electrolyte level is too high, which will cause excessive pressure inside the battery. In severe cases, the battery will explode.

  3. Add at any time
    In the routine maintenance of the battery, when the electrolyte is insufficient, usually distilled water should be added. However, sometimes the electrolyte is reduced due to cracks in the battery case or cracks in the electrolyte pores. However, some drivers usually do not pay attention to distinguishing the damage of the battery casing or other reasons, which are caused by electrolyte leakage or normal loss. As long as the electrolyte level is reduced, distilled water is added, resulting in a significant decrease in electrolyte density. Make the battery not work properly. Some drivers often add distilled water after picking up the car. As a result, the added distilled water cannot be fully mixed with the original electrolyte of the battery, which easily causes the battery to self-discharge or damage the battery plate, and the battery may partially freeze in severe cold areas. . Phenomenon, affecting the service life of the battery. On the other hand, if distilled water is added to the battery before the vehicle is taken out, since the generator continuously charges the battery while the vehicle is running, the added distilled water can be fully mixed with the original electrolyte in the battery, and the battery performance is not affected. Therefore, distilled water should be added before leaving the car, and it is recommended not to add distilled water after the car is running.
