I don't think this is the case.  A float charge will pretty well ruin a 
battery in 3-5 years whether it's used or not; just look at what it does 
to 
UPS batteries.  The continual overcharge results in positive grid 
corrosion.

Your mileage may vary.  There is almost as much art as science to battery 
maintenance. ;-)

I don't know what you mean by this.  Can you explain?
