To safely change your car battery, first ensure the engine is off and wear protective gloves and goggles. Locate the battery and disconnect the negative (-) terminal before the positive (+) to avoid sparks. Remove any hold-down brackets, lift out the old battery carefully, and clean the battery tray and terminal connectors to remove corrosion. Place the new battery in the tray, secure it, then connect the positive terminal first followed by the negative terminal. Finally, check your car’s electrical systems to confirm the installation was successful. Dispose of the old battery responsibly at authorized centers to protect the environment
