1. The first charge of the battery without the initial charge is called the initial charge, and the initial charge has a great influence on the service life and charge capacity of the battery. If the charge is insufficient, the charge capacity of the battery is not high, and the service life is short; if the charge is over, the electrical performance of the battery is good, but it will also shorten its service life, so the new battery should be charged carefully. Regarding the dry-charged battery, according to the instruction manual, although if it needs to be used within the specified two-year storage period, it can be put into use as long as it is added with the specified density of electrolyte and left for 15 minutes without charging. However, if the storage period exceeds two years, due to partial oxidation on the plate, in order to increase its charge capacity, supplementary charging should be carried out before use, and then used after charging for 5h-8h. 2. No supplementary charging. Some drivers often neglect the supplementary charging of the battery in the car. Because the battery is not fully charged in the car, it is easy to cause the plate to vulcanize; at the same time, the charge and discharge of electricity in use are unbalanced. If the discharge is greater than the charge and the battery is in a long-term loss of power, the battery plate will slowly vulcanization. This kind of chronic vulcanization will reduce the charge capacity of the battery until it is weak to start, which greatly shortens the service life of the battery. In order to restore the active material on the battery plate in time, reduce the vulcanization of the plate, increase the charge capacity of the battery, and prolong its service life, the battery in the vehicle should be recharged regularly. 3. The battery is overcharged. The battery is often overcharged. Even if the charging current is not large, the electrolyte will boil for a long time. In addition to the fine particles on the surface of the active material, it will also cause excessive oxidation of the grid, causing the active material to loosely peel off from the grid. . 4. The polarity is reversed during charging. Due to the different materials of the positive and negative plates of the battery, in addition to the active material, the negative plate is also added with materials such as barium sulfate, humic acid, carbon black and rosin to prevent the negative plate from shrinking and oxidizing. In addition, the number of negative plates in each single-cell battery is always one more than the number of positive plates, and the negative plate is slightly thinner than the positive plate. When initial charging or supplementary charging of the battery, if you do not pay attention to the polarity, the battery will be reversed, and the positive and negative electrodes will almost become coarse-grained PbSO4, resulting in insufficient charge capacity of the battery, not working properly, or even causing the battery scrapped. Therefore, you must pay attention to the polarity when charging and never reverse the polarity. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
