Choosing the proper battery at installation improves reliability, supports fuel efficiency indirectly by reducing alternator strain, and ensures compatibility with vehicle systems that may need battery registration. For warranty-covered work, remember that service must be completed at a certified dealership to preserve protection and guarantee that the correct battery type is installed.
