Interesting. I had battery maintainers (either solar on dash or
plug-in) on all my ICE vehicles over the years. Mostly because they
typically didn't move for weeks at a time as there was pretty much
always an EV of some kind in the driveway to do most of my trips.
It didn't occur to me to put one on the Leaf due to the big DC-DC
converter from the traction pack that should be maintaining the 12-volt
auxiliary.
I'm content that the failed 12-volt battery had served its time and I
think served past its expected life.
As for battery maintainers, I can come up with one of those pretty
easily (I sell an intelligent version). I should put one on the current
gasser - my SO will love having an electric plug hanging out from the
front grill (actually, not so much). Not so unusual around here where
we still have a lot of gassers with either battery blankets or block
heaters or both to improve chance of engine starts on truly cold days.
(Back in my pre-OEM EV days, I carried jumper cables so I could tap the
traction pack to jump start frozen gassers on the cold days. Can't do
that now on the factory EVs because I can't tap the pack or boost from
the auxiliary per the owner's manual. So now I carry one of the tiny
jump packs for that purpose.)

That's exactly what the leaf does with a flat 12V battery.
Just replace it, and put the new one on a battery maintainer. Under
$200 at Batteries & Bulbs, expect a 3 year lifetime for the 12v
battery, maye 4 with the maintainer.
