I want to get an electric car and I found a 2012 Nissan Leaf SL for 6.5k with 65k miles on it near me and it has 10 bars of its capacity left. I live in Orlando Florida and I don't have a garage to park it in to avoid the heat. I will be driving around 25 miles every day and plan to use 120v charger. How fast will the battery degrade?
