How to Replace a Car Battery?
3 Answers
Park the car, pull out the car cigarette lighter, insert the memory card, and save the settings for the vehicle identification number, radio, and navigation system. Open the engine hood and locate the car battery. Disconnect the battery cables and remove the old battery. Install the new battery.
Changing a car battery requires careful operation, safety first. Prepare the new battery, wrench set, and gloves with goggles. Turn off the engine and remove the key, then open the hood. Remember to disconnect the black cable (negative terminal) first, then the red cable (positive terminal). Loosen the mounting bolts of the old battery to remove it. When installing the new battery, ensure the positive and negative terminals are correctly aligned and tighten the mounting bracket. Remember to connect the red cable first, then the black cable, and secure all bolts firmly. After installation, start the engine to test the air conditioning and windows. Some vehicles may require resetting the one-touch window function after a power loss. Do not discard the old battery irresponsibly; auto repair shops or recycling centers accept them.
Just helped my neighbor replace the car battery last weekend, and it was actually quite simple. Remember to wear gloves to avoid getting splashed by the electrolyte. Park the car on level ground, turn off the engine, and wait for about five minutes to let the vehicle's computer power down for protection. To remove the battery, first loosen the black negative terminal clamp, then disconnect the red positive terminal. Use a wrench to remove the battery base screws, and you can take it out. The installation sequence is the opposite: first secure the base, then place the new battery, connect the positive terminal to the red end and the negative terminal to the black end, and tighten the clamps. Finally, don't forget to tighten the bracket screws and start the car to check if the lights and air conditioning are working normally—that means success. Doing it yourself saves over 200 yuan in labor costs!
