I would still be using this battery in my car but thanks to local help, I have a 40kw battery in my car!! I have many leaf spy screen shots to prove its health and very carefull charging efforts. it was charged 20% - 60% , 95% of the time. very few time to 100 %. I belive it can put into 2011-2012 with only leaf spy pro . or take out cells for custom battery pack. cash only.
