Procedure for replacing a car battery: 1. Open the two fastening buttons of the thermal insulation cotton to expose the red and black insulation covers on the positive and negative terminals. Lift the insulation covers to reveal the locking nuts; 2. Use a wrench or hexagonal socket to loosen the fastening nut on the negative terminal, then gently pry open the fastening block with a flathead screwdriver before pulling out the negative terminal; 3. Repeat the same method to disconnect the positive terminal; 4. Unscrew the locking strap nut securing the battery, release the locking strap, and remove the battery. When installing the new battery, simply follow the reverse sequence. Note that the positive terminal should be connected first, followed by the negative terminal, which is the opposite order of removal. This is to prevent short-circuit hazards and ensure safety.
I've changed the battery several times myself and find the process quite straightforward. First, park in a safe spot and turn off the engine, remembering to wear gloves for hand protection. Just prepare a wrench as your tool, then pop open the hood. The first step is crucial: disconnect the negative cable (the black one) first, followed by the positive red one to prevent short circuits or electric shocks. After disconnecting, loosen the battery bracket and carefully remove the old battery. Before installing the new one, check if the tray is clean. Place the new battery in, secure it firmly, and then reconnect in reverse order—positive first, then negative—tightening the terminals to avoid looseness. Once connected, start the car to test and ensure everything works fine. Pay attention to battery lifespan; typically, it should be replaced every few years. Develop a habit of regular checks to avoid being stranded midway.
