Finally made it home at 9:20. With the help of Huy's battery swap in La Porte, then swapping my now fully-charged battery in Marysville, amazingly we were able to drive all the way to Pleasanton with the voltage starting at 12.3 and dropping to 11.4. However, after the voltage dropped to 11, it started to really drop fast. By the time we got to Mission Blvd. (just 15 miles), it was down to 9.4 before it started to misfire and stumble (and really lose power). Unfortunately, we were just 11 miles from home when it was obvious we weren't going to make it, so I pulled into a Chevron at Montague/880 and called AAA.

It was a great trip. I just wish it could have been longer!

Thanks for all the help getting us home!
