$/kwh is still a lot higher for lithium than for lead acid, so lithium 12Vs aren't really a practical idea unless you have a hybrid battery that most of the accessories run off of.

Therefore for the same price the lithium battery will have a lower capacity than the lead acid battery, which will mean less ability to engine off coast in your manual transmission econobox, which will handicap maximim MPG.
