The dealer most likely does things that are profitable first...Why not just bring them the battery and get a free replacement...I got a replacement Tach, blower switch, and fuel guage to replace, exchanged at the counter when the order came in. 45 minutes later I was on the water jumping waves. The dealer was more than happy to swap warranty parts for me to install myself. I don't have time to wait for the dealer's service dept to do small replacements. I'll do them myself. If you established a good relationship with your, dealer they will be flexible back. At my local dealership the service, parts dept, and the general manager knows me by name.
