life expectancy of sealed batteries [RE-wrenches]

Wrenches,

Does anyone have some general ideas of the life expectancy of sealed 
batteries in backup applications.  I have seen charts showing so many 
cycles at such and such depth of discharge, but I am wondering how time 
enters the equation.  If the manu says 600 cycles at 80% DOD and there 
are 10 cycles per year, does this mean the battery bank will last 60 
years or even close to that?  Thanks.
