My 12V battery was dead on Friday morning. (This happens in my Leaf. No, I didn't leave it plugged in not charging or sitting for days.)
I have a smart battery tender/charger so I plugged it in and let it bring the battery back up. It's still charging now (about 40 hours later) but close to 100%.
Plugging in a L1 charger, the car beeps once and there are some clicking sounds from under the hood, but it does not start charging.
The car acts like it has full 12V power. Can put it in accessory mode and use everything. But if I try to turn the car on to drive it, it shows the little animation telling me to put my foot on the brake pedal (which I am doing), the steering wheel shakes very slightly once, and it goes into accessory mode with several yellow warning lights:
Brake system warning light (Exclamation in a circle)
Power steering warning light ("PS")
EV System warning light (Exclamation in a car)
Vehicle Dynamic Control warning light (Car with skid marks)
None of these were an issue before the 12V went out. The car is at 33% charge and I don't want to let it sit that low for too much longer. I've heard that 12V systems cause all sorts of false alarms. I'm going to take the car in to the dealer to get the 12V replaced (it's still under warranty) but I just want to get the car running so I can drive it in instead of towing.
