   In my past life as a contractor I fixed UPS units all the time.  They   
   all had 12V 7AH gel cells.  There might have been a few big units with   
   10AH batteries, but 99% of them used the same old 12V 7AH gel battery.   
      
   ----------------------------------------   
      
   I lucked onto two APC1400s at flea markets, one free-to-fix, the other $20.   
   They have true sine outputs with enough surge capacity to start my compact   
   refrigerator, so they are its power outage backup. They are older beige ones   
   that haven't been disabled with timers for off-grid (mis)use. I'm told they   
   can run continuously at 750W. The fridge draws less than 100W running. The   
   internal batteries are two 12V, 18As and the battery disconnect plug on the   
   rear is an Anderson SB50 that can be rewired from series to parallel for   
   external deep cycle input.   
      
   Their disadvantages are fairly high idle draw comparable to the fridge,   
   typical of sine inverters, and no easy way to command them On from   
   battery-powered Standby with an external load sensing circuit. That command   
   is missing from the otherwise pretty complete remote control set, though   
   it's available manually.
