Hi all, newbie here, searched the archives, sorry if I missed a thread where this was already covered...
- Replaced 12V battery.
- Car went into ready mode as normal, showing 3 bars of charge and 20 mile range.
- Turned car off, plugged in standard 110V trickle charger and first blue charge light started blinking as normal.
- Came back 5 hours later, all blue charge lights off.
- Car won't go into ready mode, display shows little red 12V battery error light and zero charge on the main battery.
- Battery still has 12.6V. Headlights, tail lights and all interior electrical stuff seems to function normally.
- Tried disconnecting battery to reset system, but still got same result as shown in the pic.
Thoughts on what's wrong, anyone? I've done some reading on the interwebs and I understand now that 12V management is a common issue, but I haven't come across the exact problem I'm having.
I bought the car 3 months ago and everything has worked perfectly until now. It has a replaced main battery with 12 bars. Five days ago the same scenario I described above happened with the old 12V battery. I hooked up the trickle charger like normal, came back about 20 hours later to find the car unable to go into ready mode, with the display as described above. Measured 12.1V with everything off, dropping to 11.7V with the car "on." Tried jumping off a running car that was putting out 14.4V, after around 10 minutes it still wouldn't go into ready mode, either while still connected or right after disconnecting the jump. Date stamp on the battery said it's 8 years old, and we were having the coldest temps of the year (in Seattle, so cold means 32ish), so I figured it was a good bet a tired old battery was the problem. Put the new battery in, everything looked good and normal, thought the problem was solved, but then after 5 hours of trickle charge it has the same problem it had with the old 12V battery (as described above in the "short story").
I just picked up an adaptor to run LEAFSpy but haven't tried it yet (sorry, it's Christmas and it's raining!). What should I look for when I hook it up?
Any and all ideas and suggestions greatly appreciated!
