Also wonder if I had the 3.3 kW onboard charger of the original car design instead of the later 6.6 kW charger, I might also not have this problem - again since the charging would take longer, leaving the built-in 12v battery maintainer on longer.
I'll definitely use that feature when I get set up with LeafSpy - thanks
I've had the 2012 3.3kw charger operating with the original battery now for about 8 months. I consistently charge level 2 when ever the battery is depleted below 20-30 miles remaining range - just so I have enough range to take a trip into Houston if needed. My Leaf is a 9 bar with limited range, so that compounds the need to keep charge near 100%. I've been monitoring the 12 volt "system" and know that it is often in the 12.1 to 12.4 volt range which is not good for the battery (SOC is below 60% much of the time). That combined with an "old" battery has prompted me to use the battery "tender" is often as I remember to hook it up. I keep a connector that is easily attached for convenience.
Your issue seems to indicate an intermittent "parasitic" type load OR a charge profile that is even worse than the "norm" and the battery is being continually but slowly drained (which could also be a very small continuous "parasitic" load?). Either way, if you can continuously monitor the battery voltage, it might tell the story. There are many posts about this issue and some have charted battery voltages that show the apparent "poor" charging profiles. It is hard to believe that many "bad" batteries!
Keep us informed.
