12v Battery Recommendations

[LeftieBiker]

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.

* 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
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.
