Has anybody seen their Leaf keep the battery at 14.4V and the 3rd charging light blinking for over 9 hours long (car not plugged in)?
I am a bit worried about the aux battery being cooked to death with such high voltage for so long, while it is pretty warm today (28degC = 82 degF) as well as my main battery getting depleted, only 3 bars left (20 mi range) and the DC/DC is humming along and the waterpumps pushing water around for cooling - all coming from the main battery from noon till 9PM so I am concerned what I will find tomorrow morning - dead main battery?
My Leaf is a 2012 that had a warranty battery replacement earlier this year (so, SW upgrades have been done)
and also needed a new 12V battery a month later.
Now again a few months later I have used the car very little until this last week, since then I have driven it almost every day, charged several times and last time was Friday night/Sat morning charged to 100% and moved the car around a bit but not really driven it any distance.
Parked the car in garage Sat night and Sunday noon time noticed the 3rd blue charging indicator blinking and soft humming (water pump) coming from car. Checked if any of the timers were active, but no climate or other timers present, so I measured the aux battery and found it to be held at 14.4V
I have searched but could not find anyone mention how long the 3rd charging light would remain blinking and 12V battery being charged without the car being plugged in. 9 hours seems to be an excessive time, especially since at the beginning of the weekend the car was charged.
Any ideas?
Seeing the history of battery failure earlier this year, could there be a malfunction that causes the car to keep charging?
As far as I know the Over-the-Air telecommunication module was not upgraded, so no Carwings should be active (no remote climate control)
Any help appreciated.
