1. When starting the vehicle, listen carefully to see if there is a “beep” coming from the engine. If so, it means the car battery is discharged. The solution to this situation is very simple: just charge the car battery on time.
2. Another situation is that the car battery voltage is low because the car battery is defective. At that time, the car owner can test the car battery and generator at the same time to see if they can work. Normally. If the car battery is found to be broken, replace it in time.
3. If the car indicates that the battery voltage is too low, but the car can turn on normally, it means the problem is not serious and the car owner can ignore it. Additionally, during daily use of the car, try to avoid turning on lights orlisten to the radio for a long time with the engine off during prolonged parking, you should also put away unnecessary electrical equipment (interior and exterior); exterior lights, audio, navigation, etc.) etc.) power is turned off.
What to do if the car battery is dead 1. Jumper lines
If your car has a jumper line, or if you can take a jumper line , you can borrow batteries from Light Your Own Car, but this method is impossible. Most car owners will not prepare their own wiring, and the operation process may also create psychological barriers and certain certainties for friends who do not understand electrical appliances or women who are shy of danger. . Although it is rarely used, there is nothing wrong with knowing it. At least you can easily save yourself when you really have oneneed. If you choose to use the wiring method to solve the problem, be sure to: connect the positive pole to the positive pole; connect the negative pole to the negative pole; Don't go in the wrong direction! Otherwise, the battery may be burned out. If the electrodes are connected backwards, causing white smoke or a burning smell, the battery should be replaced. Another possibility is that the very low temperatures in winter in the north freeze the battery. If that's the case, you can't use wiring to save yourself.
2. Cart to support the combustion
If we don't have tools around us, the easiest way is to use a cart to help light the fire. However, pushing the cart requires several conditions: first, you need to make sure that there is still some residual energy left in the battery. If the battery is completely depleted, pushing the cart will be useless.THE. Second, the push method is reserved for manual transmission models. , models with automatic transmission. The model cannot be started by pushing the cart, nor towed with a tow rope, only wiring method can be used. The principle of "pushing" a car is to use human force to push the car, and the kinetic energy reacts on the piston of the cylinder, forcing it to compress the gas in the cylinder and burn it. Before pushing the car, it is best to find a driver who is skilled in using the clutch and shifting gears to be responsible for the ignition, and find a few people to push the car behind. Before pushing the car, the driver must turn the key to the power (ON) position, then engage the gear. When the car reaches a low speed, immediately lift the clutch if the engine starts and idles normally. , It's good.. After successful ignition, do not turn off the engine and let it idle for a while to charge the battery; or you can simply
The solution to low car starting voltage is: 1. Start the carWhen driving, listen carefully to see if there is a “beep” coming from the engine . If so, it means the car battery is discharged. The solution to this situation is very simple, just charge the car battery in time; 2. There is also a situation when the car battery fails. At this time, you can test the car battery and generator at the same time to see if they are broken. can work normally, if the car battery or generator is found to be broken, replace it in time; 3. If the car shows the battery voltage is too low, but the car can turn on normally, thismeans the problem is present. It's not a big deal and you can ignore it.
