   The batteries I worked with were lead acid   
      
   The 'three year' replacement cycle does not apply to other types.   
      
   The UPS systems I have in my home were all   
   customer discards.   
      
   two of them have batteries about the same size as used i n cars. They   
   have a replacement cycle of 10 years.   
      
   The ones I have are older and still good.   
      
      
   I have at least 24 hours of backup with some of my systems
