Throughout this winter I've been reading 15 v and it's always on a battery tender. Battery measures 12.7v. After a half hour or so of driving it drops to about 14.8
Prior to that day - my max voltage has been 15.0 - with TWO Gladiators. That's pretty normal when it's cold. And yeah mine has settled down to 14.8 now, even after being on the charger for hours - COLD batteries don't do so well.
