should Car batteries when charged to 12.9v ( fully charged) stil b that voltage after 10 hours. coz mine dropped t 12.2 v and then the starter motor just sort of WIZZED first press. then started as normal. a drop charge didnt show a drop so t speak but im wondering if it's not holding its charge. i also assume been a V8 4.8..it needs more than 12.2v to turn over
