In terms of the car battery, it is really a headache when it loses power. What should we do? In fact, the problem is very simple. We can solve it as long as we know how to start the car, because after the start, the engine can drive the generator to generate electricity and thus we can drive the car. Here is how to start the car with a dead battery:

Ⅰ. The cart can be started when the car battery is dead

1. Taking into account the specific situation, if the car can flash and emit a horn when walking on the road, and only the starting motor suffers from fatigue, we can first push the car. In fact, we can put the car in two or three gear, step on the clutch, push the car, and loose the clutch when a certain speed is reached, so the car can start.

2. Propeller starting is the most intuitive and effective way to solve motor car battery failures, but it is a unique way and cannot be used often because it causes certain damage to diesel engines and clutches. Especially it is necessary to prevent automatic vehicles from using this way.

Ⅱ. The dead motor car battery can be started in an emergency

1. Bring the two vehicles close until the jumper cable is long enough to connect the positive and negative poles of the two batteries. Be careful to ensure that the two cars do not touch, and only cables with sufficient load-bearing capacity and skin insulation can be used. If it is inconvenient for the outlet of the switching power supply bottle at site to start grounding, it is necessary to use a special tool to remove the battery.

2. Determine the positive and negative poles of the two batteries, and use cables to connect the positive poles, and the negative poles respectively. Please note that the positive and negative ends of the battery cannot be wrong, and ensure the reliable connection of the cable. Set the direction of the cable to avoid scratches by the rubber or the cooling fan when the cable starts, so as to better solve the problem of no electricity in the car battery.

Ⅲ. The car battery can be charged and started when it has no power

1. If there is no power, in case of emergency, you can seek other people's help and use the battery cable to connect to another car battery to start. But it is best to remove the battery from the storage battery charge. Because the battery is completely shut down, the short-term energy storage battery of the car cannot be used to charge, so the long-term battery should be used for charging to restore the storage capacity.

2. If you have a portable charging head, you can charge the car battery immediately without removing the battery. If you drive few cars, it's best to buy one yourself. Its price is very cheap, it only costs tens of yuan. Be sure to buy the kind of smart charger with switching power supply that can be fully charged and stop automatically.
