The battery charging current is normal

Many people know the voltage of their car battery, but they don’t know how normal the battery charging current is. The battery charging current is related to the battery capacity, which is generally one-tenth of the battery capacity. The battery voltage of a general family car is 12V and the battery capacity is about 60Ah. In other words, the battery charging current of 6A is normal.

When the car engine is running, it will drive the generator to run. The electricity generated by the generator can be supplied to the car's electrical appliances, and the other part of the electricity can be used to charge the battery through the transformer. The car battery is an important part of the car. It can provide electricity for the ignition system and can also store electricity for the car.

Usually the battery of a family car is 12V, but in fact it may be higher. Generally, the no-load voltage is about 13V, and the load voltage is not lower than 11V. If it is lower than this voltage, it will cause difficulty in starting. The battery can be charged by the generator while the car is running. If the car is parked for a long time, it will easily lead to the loss of battery power and cause the car to fail to start. Therefore, during the long-term parking period, it is best to start the vehicle every other week, and the starting time is more than 5 minutes to charge the battery.

In addition, when parking for a long time, it is recommended that the owner and friends remove the negative electrode of the battery, so as to avoid the battery shortage of the vehicle. Always pay attention to the cleaning of the battery to prevent the battery wiring or wiring port from being contaminated, and check the battery regularly, including checking whether the battery shell has cracks and electrolyte leakage, whether the connection line is firm, whether the charging circuit is normal, and so on. When the battery voltage is insufficient, it should be checked and replaced in time.
