[QUOTE="Lethalthreat7.3, post: 1196078, member: 10651"] This is what I was taught way back in the 80's. Batteries have 6 cells on a 12v battery. Each one, under optimal conditions is rated for 2.3v which is equal to 13.8v. At 5% over you are at 14.49. At 10% over you come to 15.18v. It's been awhile but I believe Ford doesn't recommend over 14.5v. In my experience anything over 14.7 causes premature battery life failure as well as the heat taking it's toll on the alternator rectifier bridge and regulator(excess heat). I've found the best life on batteries and alternators is to have a charging system that operates between 13.9 and 14.2(although for short charge bursts, ie after starting and gp's) they will usually charge upwards to 14.7 until the batteries recover.
