As usual, thank you all for your thoughts.  The battery is up to 11.3 volts 
after 1.5 days on the smart charger.  I will definitely have it load tested 
when it is done charging.  As to warranty replacement- the discharge was my 
fault.  Would they still replace it under warranty under those circumstances?  
When I call Mid-state should I already have done the load testing?  Do I need 
it at steady state on the recharge before I load test it?

Mooring

Alternator on boat.  Now at home using smart charger.  Considering adding a 
solar panel since the boat sits a week at a time often with no power at the 
mooring just to be topped up without having to run the engine.  I run the 
engine quite minimally because I can sail off and on the mooring, so this would 
seem a good idea.

Isolated from what?

That is what I am doing at home.  NO way to do it on the boat.

Before I return it to the boat, I will do that and load test it.  BTW, if this 
is delayed, any reason I can't use one of my older wet cell batteries in its 
place, or is mixing AGM and wet cell a bad idea.
