How to repair the car battery?Can battery repair fluid really repair the battery?

I believe everyone is quite familiar with car batteries, which not only supply power to electrical equipment, but also protect automotive electrical appliances. But as a power supply equipment, the failure rate can be said to be quite high. However, the vulcanization of the battery is the most common one, which needs to be repaired in time. So, how do you repair the car battery, and does the battery repair fluid work?

Hydrotherapy

The concentration of battery electrolyte can be said to be a very important influencing factor. When the concentration is abnormal, vulcanization is likely to occur. As for its solution, first discharge the battery, then pour out the original electrolyte of the battery and inject it with a concentration of 1.1g/cm^3 to provide the solubility of lead sulfate. Then, in the range where the liquid temperature does not exceed 20-40 degrees, charging is performed with a current below 20h rate. After the charging is completed, the vulcanization of the battery can be eliminated, and the capacity can basically be restored to more than 80%.

Shallow cycle high current charging method

After the battery is used for a period of time, a lot of sulfide salts will naturally accumulate on the plates, which need to be removed in time. First, use the current within 5h of high current to fully charge the battery. Then, when the liquid temperature does not exceed 40 degrees, a discharge of 30% is carried out, 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 material. Then, following this process for three or four cycles, the vulcanization of the car battery can be repaired.

Battery repair fluid

The battery repair fluid that appears on the market is also a very useful repair method that can effectively restore the battery's capacity. After a full charge and discharge, the distance can be increased by 5-15 kilometers. After seven full charge and discharge, the battery capacity recovered to more than 90%, prolonging the service life by about one year. But this still depends on the situation. If the attenuation of the car battery is already very serious, even the use of battery repair fluid will not help.
