Yes, if that was the battery alone that is a rip-off. If it was the
total bill for diagnosis and replacement of the battery as well as the
battery, then I'd say it wasn't unreasonable.

Only if it is on a charger. A resting battery is more like 12.6V if it
is in good shape and depending on temperature.

I don't think I have ever seen a good one run that low but my favorite
source - http://www.batteryuniversity.com/partone-13.htm agrees with
him. That is the minimum though. We always learned that lead acid wa
2.2 v / cell. That does seem more normal.

Either way 12 is too low but we don't know how well that was measured.
By that I mean around 12 on an old mechical meter or 12.053 on a
recently calibrated DVM. It's really too bad he didn't stop by
somebody like Autozone and have it load tested before hitting the
dealer. Testing under load is the only good test as it shows up bad
internal connections as well as charge capacity.

Where did you learn that? I was always taught (I'm an EE) that 2.1V per
cell was nominal for an LA cell.

E tech - I can't say where I learned it - it was too long ago. perhaps
Navy, perhaps tech school, perhaps etc. Just out of curiosity I went
out and checked the car - 12.69. Checked back to a couple of web
sites. The only thing I can say now is none of the numbers match
exactly. ;-) OTOH discussions like this get me to relearn old
knowledge. It's good to check back on what I think I know every once
in a while.
