Here's one link that gives useful info on car battery voltages and specific
gravity. I've seen other tables that closely correspond to the table for
Low maintenance lead acid car batteries. Be sure to check the Temperature
Compensation table for battery temps other than 80F. Paragraph 4.3 talks
about removing the surface charge by waiting 6-12 hrs, but I've read other
suggestions to wait as little as 1 hour.
