Put on personal protective equipment, including gloves and safety goggles, to shield yourself from battery acid and debris.

Carefully inspect the battery for any signs of damage, leaks, or cracks. If the battery is damaged, it should be replaced instead of repaired or cleaned.

Use a small adjustable wrench to loosen and remove the negative (-) battery cable first.

Handle your tools carefully when near the battery to prevent shock or arcing.

Remove the positive (+) cable. Set the cables aside, ensuring they don't accidentally touch the battery terminals or any metal surfaces of the vehicle.
