What are the steps for replacing a car battery?

[DelValeria]

Car battery replacement steps are as follows: 1. Confirm the battery installation location. Most models are installed in the engine compartment or luggage compartment, while some models may have it in the cabin. Take appropriate body protection measures at the corresponding position. 2. Remove external protective devices such as the battery cover and measure the voltage between the two terminals with a multimeter. 3. If the vehicle has an anti-theft system (including audio anti-theft), you can first connect an external power source or parallel a fully charged battery. Note: connect the positive terminal first, then the negative. The positive terminal of the external power source can be directly connected to the battery's positive terminal post, but the negative should not be directly connected to the battery's negative terminal post. Instead, it should be connected to the vehicle's ground point. 4. Turn off the ignition switch of the faulty vehicle. First disconnect the negative cable of the battery, then disconnect the positive cable. 5. Remove the battery's fixing device and take out the battery.
