The battery has an 8 year warranty. The battery is under the car. I charge at home 99% of the time. I get about 4 miles for 15 cents of charge (Home charging). Or about $1.50 for 40 miles. I only charge to 80% unless I am going on a longer trip. I get a little over 300 miles on a full charge but at 80% its closer to 250. Every morning I start the day with the same 250 miles available. If I think I will need more thatn 250 miles I will charge closer to 100% I heard it was between 8,000-12,000 for a new battery but I don't know for sure. I only charge to 80% because any battery when fully charged can swell in heat. Over time that could be a problem. My brother has a Tesla he bought 5 years ago. He still loves the car.
