Can the car battery be repaired? How much does it cost to repair the battery once?

The battery is the power supply equipment of the car, which provides electric energy for the start of the car and the electric equipment in the car. If the battery has a problem, it will affect the normal use of the car. The life of a car battery is generally 2-3 years, and it is inevitable that some failures will occur if the battery is used for a long time. The most common phenomenon is loss of electricity and no electricity. Can the car battery in this situation be repaired? Let's understand it below.

If the car is parked for a long time and the battery is left unused, it is likely to cause serious vulcanization of the battery and loss of electricity. At this time, we can use the shallow cycle high current charging method to repair. First, use current within 5A to fully charge the battery. Then, when the liquid temperature does not exceed 40°C, discharge is performed by 30%, so that the slight sulfide salt on the surface of the electrode plate is washed, so that it is desorbed and dissolved and converted into an active substance. According to this process, three or four cycles of operation can repair the vulcanization of the car battery.

In addition, car battery vulcanization will also reduce the battery voltage. If the battery voltage is lower than 10v, the battery will not store and cannot be charged. At this time, you can use a repairer, and use the repairer's high resistance repair to increase the battery voltage again. Above 10V, then the electricity can be charged in, so as to achieve the repair effect. The price of a battery repair is usually dozens of dollars, depending on the cause of the battery failure. If the battery has been used for a long time and the vulcanization is serious, repairing is not recommended at this time, and it is also difficult to repair. It is recommended to replace the battery with a new one.
