The car won’t start even with electricity. How to repair the battery if it’s broken?

Loss of the car battery will cause the vehicle to fail to start. At this time, it needs to be charged. You can use a charger to charge, or you can use the battery to charge the battery. The battery requires a rescue vehicle to connect the battery electrodes of the two vehicles with a charging cable. If the battery loses power, the vehicle can be started soon. However, some car owners encounter a situation where the car cannot start after being powered on. What is going on? Let's understand it below.

If the car battery loses electricity, you can find other vehicles to pick up the rescue, and you need to turn off the electrical appliances on the lost tram before picking up the electricity, so as to avoid inadvertently connecting the positive and negative poles of the battery to cause a short circuit of the vehicle circuit and damage the electronic equipment of the vehicle . If the car cannot be started even if the car is powered on, it may be that the cable is not thick enough. Generally, when purchasing a car cable, you should choose a genuine quality-guaranteed cable. Try to choose a thicker one with an outer diameter of at least 10mm.

In addition, the failure of the car to start may also be due to insufficient charging time. Generally, it is necessary to start the rescue vehicle to run for a period of time after the power is applied, wait for about 5-10 minutes, and then start the vehicle that is losing electricity. If it can be started, the lost tram will need to continue to run for about 30 minutes to allow the generator to charge the battery. If it still fails to start, it may be that the car's engine is faulty, and you need to go to a repair shop or 4s shop for overhaul.

If the battery is used for a long time, vulcanization may occur. The battery with severe vulcanization cannot hold the electricity, which is equivalent to scrapping. However, the cost of replacing the battery is relatively high. Some batteries cannot be recharged after a short period of time. It is a pity that they are scrapped. How to repair it? If the vulcanization is not serious, a small current can be used to charge the battery, which generally takes more than 12 hours; if the vulcanization of the battery is serious, the electrolyte needs to be replaced before charging.
