I returned from a 2 week vacation last Monday, needed to go to the store but the car would not start. A lot of error lights came on and I recognized the dead battery problem because I had seen it a few times before. The problem this time was I could not turn the car off no matter what I tried.
I tried to connect my battery charger to the car but it acted like the battery was a dead short the circuit breaker on the charger would keep cycling.
I took my wifes car to the store and when I returned, my car had shut off. I measured the voltage on my battery at 4.5 volts.
I connected my charger to the battery and after a few hours the battery was up to 12 volts and the car would start.
Today I took the car to my Honda dealer for a battery check which was good.
My main question though is how large LI battery do I need to carry in my trunk for an emergency start where I don't have to wait more than a few minutes for the battery voltage to get high enough to start the car. Any one with experience with that?
