The car battery is a very important part of the car. It can be used for 5-7 years, but it can only be used for 1-2 years. In fact, we only need to make sure that the electricity is not turned off, and the electricity is not turned off.
Playing music in the blackout state and blowing the air conditioner will cause great damage to the battery. Excessive time will cause the battery to run out of power and cause fire. It also has a great impact on battery life.
When using the electronic system in the car, we must use it when the engine is running. The engine runs to drive the generator to work together. This can ensure that when we use the electricity in the battery, the generator is also continuously supplying the battery Add power.
When we started the engine in the morning, we felt that it was difficult to start because the battery was low. If it is difficult to start in winter, it is the reason for the low temperature. Some cars have a cold start system. Insufficient battery power causes insufficient engine speed, so it is difficult to start.
At this time, we have to check whether the battery power is enough. When the battery is stopped, the voltage should be between 11v and 12v. If it is lower than 11v, it means that the battery is insufficient.
There is an observation hole above the battery, green is normal, black needs to be charged, and white needs to be replaced immediately. The observation hole turns white to indicate that the battery is not charged. There was also a reaction from the owner, the observation hole was green, but the battery was low. In fact, this is just for reference only, it depends on the actual use.
Sometimes we see a bulge on the battery. In this case, we need to replace the battery immediately to prevent the battery from igniting or exploding to hurt people.
At night I sometimes wait for a red light while driving. If we find that the headlights are weak at idle speed, it will be brighter with some oil. You have to check if the battery is charged or if the generator has enough power. Under idle speed, it is normal for the generator to generate power at 14v and not lower than 13.5v.
