Keep in mind these batteries are warrantied. I don't know of any AGM that after being properly charged can been seen drooping into the 1.280's after a few days.
Given a full life cycle that battery is going to fail quicker than those units that maintained a tenth or two higher resting voltage.
When I went through pallets of Golf car T-105's I culled those 6.35 volts. They were same day products picked up direct in Santa Fe Springs. The culls went to single unit off-the-street T-105 purchasers. The rest were golf course cherry-picks. All of my Lifelines arrived showing voltage at the 13.00 mark. All the winners and all the losers get a top charge. Jeez I got better things to do then suffer premature battery problems.
Even that snotrag Gohner calcium/calcium flooded battery in the toad passed the 13.00 test and whadd'ya know here it is at the 5-year point. But it is under storm trooper supervision never to see the slightest cycling.
