Park on a level surface, turn off the engine, and remove the key.
Locate the battery: Usually in the engine compartment or trunk.
Disconnect the negative (-) terminal first: Loosen the nut with a wrench and remove the negative cable.
Disconnect the positive (+) terminal: Repeat the process for the positive cable.
Remove the old battery: Unscrew or unclamp the battery hold-down.
Install the new battery: Place the new battery in the tray, ensuring correct positive (+) and negative (-) terminal placement.

Connect the negative (-) terminal last: Tighten the nut securely.
