How can you find out what kind of battery you have in your leaf? I have a 2015 leaf which I bought mid july. I believe I have a 30kwh battery as opposed to a 24kwh battery. I understand that I have a 5 yr or 60,000 mile warranty on battery & to replace battery costs $9k including installation & taxes. I have about 1yr left & only 25k miles. Has anyone else been in this situation? It sounds like Nissan Goodwill program doesn't really work from some of the posts I have read. I look forward to your responses. Thanks.
