Many people use lead-acid batteries, there is not much attention, think that they will use it, they can be charged without electricity, and there is no reasonable use and cause the battery life to decrease, and push the responsibility to the manufacturer. The most common there are four charging misconceptionsFirst, the new lead-acid battery does not perform initial charging
The first charge of the lead-acid battery is called initial charging, and the initial charging has a great influence on the service life and charge capacity of lead-acid batteries. If the charging is insufficient, the lead-acid battery charge capacity is not high, the service life is short, and the number of charging is also increased; if the charge is over, the lead-acid battery electrical performance is good, but it will damage the lead-acid battery itself, shorten its use. Life, so the new lead-acid battery should be careful to carry out initial charging.
For ordinary lead-acid batteries, it must be charged according to the charging specification before use. For dry load lead lead-acid batteries, it is necessary to use the specified density of the electrolyte for 15 minutes according to the specified density, which is required to be used in the specified density of the electrolytic solution. However, if the storage period is more than two years, it has partial oxidation on the plate, in order to improve its charge capacity, supplement charging should be supplemented before use, and then charge for 5 hours to 8 hours.
Second, lead-acid battery excess charging
The last point has been tone to the lead-acid battery initial charging should not be charged. However, after normal use, it is often charged, even if the charging current is not large, the electrolytic liquid is "boiling", in addition to the small particles of the surface of the active material, it is easy to take off. The grid is also overexplored, resulting in loose peeling of the active substance and the grid.
Third, the lead-acid battery is not supplemented with charging
This is for the start-type lead-acid battery, some drivers often overlook the supplementary charge of the lead-acid battery in the car. Since the lead-acid battery is charged in the car, it is easy to cause a polar vulcanization; at the same time, the electric charge of the discharge is unbalanced in use. If the discharge is greater than charging, the lead-acid battery is long in a loss, lead-acid battery The plate will slowly vulcanize. This chronic vulcanization causes the lead-acid battery charge capacity to decrease until the start of weakness, greatly shortens the life of the lead-acid battery. In order to reduce the active material on the lead-acid battery plate, reduce the vulcanization of the plate, increase the charge capacity of the lead-acid battery, extend its service life, and supplement charging in the lead-acid battery in the use vehicle.
Fourth, the polarity of charging
Due to the different lead-acid battery positive and negative plate materials, in addition to the active substance, the negative electrode plate also adds material such as barium sulfate, humic acid, carbon black and rosin to prevent contraction and oxidation of the negative electrode plate. In addition, the number of negative electrode plates of each single lead-acid battery is always more than the number of positive electrodes, and the negative electrode plate is slightly thinner than the positive electrode plate. When the primary charging or supplement charge of the lead-acid battery is performed, if the lead-acid battery can be contaminated, the positive and negative electrodes are almost turned into the PBSO4 of the crude grain, resulting in insufficient lead-acid battery charge capacity. Normal work, even leads to lead-acid batteries. Therefore, it is necessary to pay attention to polarity when charging, and it is unpolated.
