   If it is a True AGM battery there is NO effect on the battery during   
   Inverted operation   
      
   This from the Internet:   
      
      
   A relatively new type of sealed battery construction that uses saturated   
   absorbent glass (boron silicate) mats between the plates instead of a   
   gelled or liquid electrolyte. AGMs batteries are more expensive than the   
   flooded (liquid) variety but offer a number of advantages.   
      
   Since all the electrolyte (acid) in AGM batteries is contained in the   
   glass mats, it can't spill, even if the battery is broken. Being thus   
   non-hazardous, AGM batteries are cheaper to ship. Additionally, since   
   there's no liquid to freeze and expand, they're practically immune from   
   freezing damage.   
      
   Nearly all AGM batteries are recombinant, which means that the oxygen   
   and hydrogen recombine inside the battery. Recombinant batteries use gas   
   phase transfer of oxygen to the negative plates to enable recombination   
   back into water while charging, thereby preventing the loss of water   
   through electrolysis. The recombining is typically more than 99%   
   efficient.   
      
   AGMs have a very low self-discharge - from 1% to 3% per month is usual.   
   As a result, they can sit in storage for much longer periods without   
   charging than standard batteries.   
      
   That is of course if the battery is disconnected in storage.
