How to change the car battery

Car battery replacement steps: the battery is broken from the negative electrode. The power-off of the battery should be cut from the negative pole of the battery first. If it is careless from the positive pole, it may come into contact with the body and iron, causing a short circuit and burning of the body electrical appliances. The storage battery is off the positive electrode.

When disassembly, remove the negative pole of the battery pile head first, and then remove the positive pole; when installing, install the positive pole first and then install the negative pole. The battery ampera and model should be correct. Before folding the battery, find a battery connected in parallel with the battery to be replaced. Otherwise, the power supply will be cut off. Some door glass needs to be matched.

Find the location of the battery - the battery should be within reach of any side of the frame. The battery is a rectangular box with two cables. The batteries of some European cars (some BMW cars) are located in the trunk, while the batteries of some Chrysler cars are located in the tire fender.The latter is usually difficult to disassemble.

Where is the car battery usually placed?

1. The installation position of ordinary passenger car batteries is generally in the engine compartment or under the passenger seat. Some models may also be installed under the trunk spare tire, such as Mercedes-Benz, Audi, etc. The Audi A4 car battery is installed in the trunk under the spare tire.

2. Car batteries are generally installed in the engine compartment in front of the car. Open the hood of the front of the car, and the battery is next to the engine. A few cars are installed in the area below the co-driver's seat, such as Wuling vans.

3. Generally, the engine of a car is in the front of the car. Open the hood of the front of the car, and the battery is installed in the engine compartment.The battery is next to the engine. Or in the area below the passenger seat. Some models are installed under the trunk spare tire. Mercedes-Benz and Audi are usually in the trunk. Personally, I think it's because the engine is too big to fit in the back.

4. The installation position of the battery of an ordinary passenger car. Most car engines are in front of the car. Open the front cover of the engine, and the battery is installed in the engine compartment next to the engine. Or in the area below the passenger seat. Some models are installed under the spare tire of the trunk. Mercedes-Benz and Audi are usually in the trunk.

5. Car battery position: Generally, open the front engine cover, and the battery is installed in the engine compartment. The battery is next to the engine or under the co-driver's seat. Some models are installed under the spare tire in the trunk.

Car battery replacement skills

First of all, we need to open the hood of the car and expose the part of the battery in front of us. We can clearly see that there are two electrode wires, one is red and the other is black, so what we see is red That is, the positive pole of the battery is black, that is, the load negative pole of the car body, and the red positive pole is removed first.

At this time, it is best to wrap the connector head with insulating tape to prevent the positive and negative poles from being connected together when they are not careful, causing a short circuit of the car circuit. Next, the battery can be taken out.

Disassemble the positive joint: disassemble the positive joint in the same way; remove the locking belt: unscrew the nut of the locking belt used to fix the battery, loosen the locking belt, and then take out the battery.

Buy the correct battery replacement. Method 2: 3 things to do before removing the battery First: Ensure environmental safety. Second: Pull out the car cigarette lighter and insert the memory into the cigarette lighter socket.

The car battery must be turned off when disassembling and installed. First, open the engine cover of the car, and you can see the car battery directly. There are two wires, one is red and the other is black. The red is the positive pole of the battery, and the black is the negative pole of the battery.

How to replace the car battery? During the replacement, the battery of the confirmed vehicle needs to be replaced. For example, it is recommended to replace it when there are often weak start-up, inability to start-up, and normal service life.

What is the method of installing car batteries?

First of all, we need to open the hood of the car and expose the part of the battery in front of us. We can clearly see that there are two electrodes, one is red and the other is black. So the red we see is the positive pole of the battery. The black is the load negative pole of the car body, and the red positive pole first Remove it.

The power supply of the car is a DC 12V battery. Because the capacity of one battery is not up to it, one battery can be added.

The specific steps for installing the secondary battery are as follows: first, connect the positive pole of the vehicle's original battery to the fuse box, so that the wiring can be penetrated from the engine compartment into the cockpit and connected to the air switch, and then connect the air to the positive pole of the secondary battery, and finally connect the ground wire of the secondary battery. That's it.

As for the installation order of car batteries, just follow the opposite steps. But when we install, we must follow the order of positive poles first and then negative poles (as opposed to the order of removal). Because after connecting the negative pole, it is equivalent to forming a loop for the car.
