I have 2 weeks of voltage and current datalogs taken at 1 second intervals. The absorption phase seems adequate if you drive it enough. If you aren't driving far or often, add a tender. Mine had the integrated solar panel, but didn't work because it was parked inside. I sold the Leaf in 2014 and it's battery was fine. In fact, I think the Lead outlasted the Lithium from what the second owner told me.
I don't know of any 12v Lithium replacements that mid-balance. All are top-balance, so if you believe what people are saying, then it most definitely will NOT stay in balance.
