Re: 12v Battery Recommendations

So if EV is used daily extra capacity has zero effect on battery longetivity.
Two points:

* Many EVs are not used daily, and some not even weekly.

* There is anecdotal evidence that the Leaf does a better job of charging higher capacity lead batteries than it does lower capacity lead batteries.

But they do the best job of charging LiFePO4 12v batteries :D
At the end of the day, you can't "fix" the inherent problems of Lead Acid batteries...and there are many more (good) Lithium options now than when I installed my LiFePO4 12v over 5 years ago.

I assume that this is because lithium batteries have a charging profile that fits the Leaf's charging algorithm well. Since better AGM batteries also work, and cost much less, that's the route I suggest for most people. The Leaf may well have been initially designed for a lithium accessory battery. We can at least be fairly sure that it wasn't designed to sue a cheap little starting battery.
