What is the method for installing a car battery?

[LeMadelyn]

Car battery installation method involves parking the car on a flat surface, turning off the engine, and disconnecting the power; using a screwdriver to remove the battery cover; disconnecting the battery cables, ensuring to remove the negative terminal first, followed by the positive terminal, etc. The positive and negative terminals of the battery must not be reversed. Car battery installation method: Loosen the negative terminal nut, open the two fastening buttons of the insulation cover, and you will see the red and black insulation covers on the positive and negative terminals. Flip open the insulation covers to reveal the locking nuts; disconnect the negative terminal, use a wrench or hex socket to loosen the fastening nut of the negative terminal, then gently pry open the fastening block with a flat-head screwdriver, and then pull out the negative terminal; disconnect the positive terminal using the same method; loosen the locking strap, unscrew the nut that secures the battery's locking strap, release the locking strap, and then remove the battery; when installing a new battery, simply follow the reverse steps, but it is important to note that when connecting the positive and negative terminals, the order is "positive first, then negative," which is the opposite of the disassembly sequence, but the principle remains the same—to prevent short-circuit hazards and ensure safety.
