Self-help when the automatic battery is dead

I believe that most car owners have experienced the dilemma of a dead car battery, and many new drivers may have heard of it.Manually geared vehicles can start the engine through the cart,Will ask:"Then how can we save ourselves when the battery of our automatic transmission vehicle is dead?"

Since it is very dangerous to start the engine on a cart, do not do it regardless of whether it is manually geared by an old driver. Because we can also help ourselves in a gentle and non-violent way, and both manual and automatic gears are applicable. Of course, I believe that many people also know this method, the battery charging method.

Before the battery is powered on, we have to prepare a vehicle with a normal battery as the rescue vehicle, and then prepare two wires for the connection.

1.First find the battery positions of the two vehicles and pair them first to ensure that the rescue vehicle is in a flameout state.

2.First take a wire to connect the positive poles of the batteries of both vehicles. Then take another wire,Connect the battery negative pole of the rescued vehicle to the engine block of the rescued vehicle (do not connect the negative pole of the rescued vehicle's battery).

3.After making sure that the wire connection is correct, start the rescued vehicle first, and then start the rescued vehicle.

4.successAfter starting the rescued vehicle, the wiring can be removed, and the removal sequence should be the reverse of the installation sequence. That is, first remove the negative electrode on the engine block of the rescued vehicle, then remove the negative electrode on the battery of the rescue vehicle, and finally remove the positive electrode of the battery of the rescue vehicle and the rescued vehicle.

PS:The reason why the negative terminal of the rescued vehicle needs to be connected to the engine block is to shorten the current loop and reduce the resistance, so as to better start the rescued vehicle. It can also prevent battery damage.
