Removing battery cables is a task that requires caution but is manageable. Always start by turning off the vehicle. Then, remove the negative cable first by loosening the bolt with a wrench and gently lifting the cable off. Follow by removing the positive cable in the same manner. To reconnect them, attach the positive cable first, then the negative one. This order prevents potential short-circuits by avoiding any contact with the car's grounded surfaces while the positive cable is disconnected.
