[QUOTE="Ven0m, post: 8674455, member: 676151"] My battery recently took a ****, so i went out and purchased a Optima Yellowtop which is apparently supposed to read 13.1v fully charged however ive never seen it go over 12.8v. I ran a voltmeter into the car and noticed that while driving sometimes the voltage drops from 14.5v to 12.5-8v and then maybe 10 minutes later it will go back to 14.5v this really has me stumped and i really dont want to damage my new battery. Bad Alternator? No lights on dash or anything [/QUOTE]
