This step is critical on modern vehicles; improper registration can lead to charging inefficiency, warning lights, or shortened battery life. Routine battery checks help identify degradation early so replacement can be scheduled conveniently, avoiding unexpected no-start situations. Beyond convenience, dealer replacement safeguards warranty eligibility: any repairs or replacements covered under warranty must be completed at a certified dealership. Our team uses genuine or manufacturer-approved batteries and provides clear timelines — most replacements are completed within a couple of hours — and a final system check to confirm all electronics and start-stop functions operate as intended.
