Op again. My question was what should you expect as "normal" or acceptable discharge of a 12 volt wet cell that is connected to nothing, just sitting on the floor. .10v per week, month?
Batt 2 is normal. It will get down to 12.75 after a few days then very slow decline after that. Batt 1 dropped too far too soon.
Your problem is to return that Batt 1 under warranty and then not have a new one to go with the older Batt 2 .
One solution is to get two new ones and keep that still good Batt 2 for some other job. Maybe give it its own 300w inverter and use that to watch TV so the other two don't get down so soon while camping. Whatever--lots of possibilities.
