Actually I rounded that off... it was 12.92. It had been on the charger for a few hours earlier in the evening. However, the charger indicated it wasn't done when I turned it off, said the battery was only at 90 percent (and was still pumping in 2.4A on a 12A charge setting).
If I take that car to work tomorrow, I will wait and listen for the relay to click off before I fire it up.
