Misunderstanding of battery charging

by:Power Kingdom     2021-07-13

  The battery is not charged at the beginning:

   The first charge of the battery is called the initial charge, which has a great impact on the battery's service life and charging capacity. If there is a lack of charging, the battery's charging capacity is not high and its service life is short; if the battery is charged too high, the electrical function of the battery will be shortened, but the service life will also be shortened, so new batteries should be charged carefully at the beginning. Generally, the battery must be charged according to the charging standard before use. For dry-type rechargeable lead batteries, according to the operating instructions, although they only need to participate in the specified electrolyte density for 15 minutes during the regular two-year storage period, they can be put into use without charging. However, if the storage time exceeds two years, due to partial oxidation on the board, in order to increase its charging capacity, it should be recharged before use, and then used after charging for 5h-8h.

  Batteries cannot make up for electricity

  Some drivers often ignore the battery supplements in their cars. Because the battery in the car is incomplete, it is easy to form plate vulcanization; at the same time, when charging is used, the discharge is unbalanced. If the discharge is greater than the charge, the battery is in a state of power loss for a long time, and the battery plate will gradually vulcanize. This slow vulcanization will cause the battery's charging capacity to continue to decline until it fails to start, greatly reducing the battery's service life. In order to reduce the active material on the battery board in time, reduce the vulcanization of the board, improve the charging capacity of the battery, and prolong the service life of the battery, the battery in use should be compensated regularly.

  Battery overcharge

  Batteries are often overcharged, even if the charging current is not large, but the electrolyte is long-term' 'Juan Teng

   The polarity charge is reversed during charging

   Due to the difference in the positive and negative plate data of the battery, in addition to the active material, the negative electrode Barium sulfate, humic acid, carbon black and rosin are also added to the plate to prevent shortening and oxidation of the negative plate. In addition, the number of negative plates per battery is always one more than the number of positive plates, and the negative plates are slightly thinner than the positive plates. When the battery is initially charged or compensated, if you do not pay attention to the polarity, the battery will be recharged, and the positive and negative electrodes will only become coarse particles of PbSO4, resulting in insufficient battery charging capacity, inability to work normally, and even failure of the battery. Therefore, you must pay attention to the polarity when charging, and the polarity cannot be reversed. Contact: 18038382979
