Since it's safely in my garage and I have another vehicle accessible, it's not an emergency. I'm more concerned how the 12v could be dead after only two weeks while the main battery is being kept at 80%+ charge and plugged in to utility power (120v/15A, but utility nonetheless). I'd like them to make sure the battery isn't defective. (Is there a trickle charger to top off the 12v? If so, perhaps that's not functioning?) If it happened once, what's to stop it from happening again after a jump?
