I usta have TELCO 2 volt cells that were 35 years old, and still 
in excellent condition.  The durability of lead cells is related 
to the density of the sulfuric acid (these being 50% of vehicle 
types) which affects the power density... duh! 
 
And, the depth of discharge affects the rate of sulfation, from 
zero for a battery that stays 90% charged, to 100% for a cell in 
complete discharge.  Like you say Roy, there aint no free lunch.
