Good question. There is a little fluctuation, no more than 0.2V though. While driving, I'm seeing 13.4-13.6V.
What I don't understand is how it could start after sitting for a couple days, be driven 12 miles, sit for five hours and then not start.
Then, after being jumped, driven home another 12 miles, sit for a couple days and start again.
It doesn't make sense that this little bit of driving would adequately charge the battery, but what do I know!
