At 8:45pm the green light on the charger went solid indicating FULL. Just before that voltage was at 14.55V and then it dropped to about 13.23V in FLOAT mode.
Spiked, did you're drop after you took it off the charger to 13v? Is that bad? I've always heard that 12.8v is good for 12v batteries. Below 12 and it may have a problem. The Battery Tender manual says if you ever see 9V, the battery is assumed to be done.
