How long does it take to turn on the battery in the car, it will be dead, what should I do if the battery in the car is dead?

I believe that many car owners have a deep understanding of the fact that the car has been parked for a period of time without driving, and when the next time it is driven, it willFindThe startup is not smooth anymore. In fact, to put it briefly, even if the car is not turned on, the battery is still consuming electricity. Today we will take a look at how long the battery will be dead if the car is not turned on, and what to do if the battery is dead.

The car battery is basically a start-up lead-acid battery, and any battery has a characteristic, that is, self-discharge.In other words, even if the car battery is not connected to any electricalYuanWithout any load, the battery will still consume power gradually. Of course, the size of the power consumption has a certain relationship with the manufacturing process of the battery.

Generally speaking, if the vehicle is not turned on for half a month, although the battery is still charged, the voltage has dropped, making it difficult to start. If the vehicle is parked for more than three months, the battery is almost completely discharged. Seeing this, there must be a car owner asking, how to avoid stopping the discharge battery for a long time? It's very simple. Start the vehicle every week to charge the battery. Pay attention to the vehicle running time longer, otherwise the charge power will not be enough to discharge the power. In addition, if there is no way to charge it regularly, you can disconnect all the battery cables.

What should I do if the battery in the car is dead?

1. The cart has the lowest start-up cost, but it is time-consuming and labor-intensive, and the prerequisite is that your car is manually geared, and the automatic gear cannot be started with the help of the cart due to the transmission structure.

2. Start by electrifying or car emergency power. The principle of emergency power supply is similar to that of power-up. Below we will mainly talk about the method of power-up. Prepare two battery cables, and then put the two cars head-to-head together. Find the batteries of the two cars and distinguish the positive and negative poles of the batteries. Do not reverse the positive and negative poles, otherwise the positive and negative connections will cause a short circuit. First, connect one end of the positive battery wire to the positive terminal of the battery of your own vehicle, and connect the other end to the positive terminal of the battery of other vehicles or the positive terminal of a separate battery.

One end of the negative grounding wire is connected to the negative terminal of the battery of your own vehicle, and the other end is connected to the negative terminal of the battery of other vehicles or the negative terminal of a separate battery. Take care that the metal wire part does not touch the body during the grounding process to prevent short circuit.After the battery cable is set up, the vehicle can be ignited.successAfter starting, remove the battery wires one by one, taking care not to touch the metal body or other parts.

3. For vehicles parked for a long time, it is a good way to use a charger to restore the battery power. However, it should be reminded that the operation of the charger needs to be cautious. If the operation is improper, the battery may be damaged.
