It seems that the 12 V battery is one of the major sources of problems in the Leaf, and even if it is never discharged unexpectedly, it still has to be replaced every few years. I'm puzzled as to why this nexus of failure modes and maintenance hassles is necessary at all. Why can't the 12-V systems be served by a DC-DC converter? Design inertia? Some obscure regulatory issue?
I remember years ago being surprised when a friend told me it was time for a new 12 V battery in his Prius, and at the time I just considered it a curiosity to be filed away for later consideration. With a new-to-me Leaf in the driveway, this seems like a good time to consider it.
I imagine this has come up here from time to time, but the 12-V threads I've looked at have just taken it as a given and are more focused on practical aspects of avoiding discharge, etc. So if you know something about this, share it, and if not, feel free to speculate!
