How to change the car battery

1. Steps for replacing the car battery: 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.

2. Disassemble the old battery (1) Confirm the installation part of the battery. Most models are installed in the engine compartment or luggage compartment, and some models are also installed in the cockpit. Take good body protection measures in the corresponding position.

3. 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, and the battery ampere 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.

Car Battery Replacement Skills

1. Car Battery Replacement Steps: Battery Disconnected and 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.

2. Replace the battery - Put the new battery into the place where the old battery was removed before, and connect the positive and negative poles to the correct side.Reconnect the positive pole - tighten the clamp with a wrench. Reconnect the negative pole - tighten the clamp with a wrench.

3. 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. Black is the load negative pole of the car body, and the red positive pole Remove it first.

4. Correct operation of changing the car battery: remove the old battery first and confirm the battery part; remove the battery protective cover; turn off the ignition switch of the faulty vehicle, disconnect the negative connection cable, and then disconnect the positive connection cable. If it has a ventilation tube, it should be removed first. Remove the fixing device of the battery and take out the battery.

The battery price of a pure electric vehicle is one-third of the whole vehicle. The battery capacity of each new energy vehicle is different. For models with a range of more than 400 kilometers, the battery capacity is basically more than 60 kwh, that is to say, the battery price is more than 90,000 yuan.
