The current required to start a Leaf is low, so unlike a slowly turning over ICE engine to warn you, you have little or no warning when the Leaf's accessory battery starts to get low. The new battery should have come with at least 80% charge. The point being made is that, Gerry's experiences notwithstanding, some Leafs do not do a great job of charging their accessory batteries.
Especially the early years (2011 and 2012).
I've got the original 12V battery in my 2014. Been on external charge exactly once.
10.5V is extremely low. That battery is toast if you've been driving the car and it's not charging higher than that.
I have a 2011 and put it on an external maintainer every 2 months just to top it off. There's someone here who posted a graph showing that the early model years slowly let the 12V battery rest to around 50-75% of a full charge, which results in premature wear on the battery. I also have a deep cycle battery to make it more resilient to being stored at partial charge.
I actually installed a 12V hookup where the QC port would be (I don't have QC) so I could easily connect the 12V maintainer to the car. Came in handy during COVID lockdown when I was only driving once a week or less.
