It either charges for a fixed amount of time or to a too-low voltage. As a result the 12 volt battery in a pre 2014 will be chronically undercharged unless you use an external charger once or twice a week...
So the 2014+ Leafs have an improved charging algorithm? Haven't heard of this before, is it posted somewhere?
If so, are the pre-2014 Leaf's capable of having the ECU, e.g. the BMS, responsible for 12 battery charging re-flashed?
My 2013 has never had any 12 volt battery issues and I don't use a maintainer, although my SL with PV cell
does supply about 50ma in moderate sunlight over the standby battery drain of about 30ma.
