   repair APC Smart-UPS: any dangers lurkin

   Moin   
      
   My trusty old APC Smart-UPS SU-1500 is still working fine   
   generally, only that the C13/C14 output jacks in the back   
   (made from plastic) have become so brittle as to crumble   
   under the slightest pressure, so that one cannot   
   plug in anything anymore.   
      
   So I want to try and wire in new sockets. SHould be easy   
   enough, but:   
      
   After I remove the battery, and of course disconnect it   
   from mains etc, *and* disconnect the battery-connection   
   plug/socket safety at the back....   
      
   Could there still be any dangers (large, slow-dissipation)   
   capacitors lurking inside  that might give me a nasty surprise   
   (I know camera flashlights are dangerous that way), or should   
   it be safe after 1-2 days off any power-source?   
      
   thanks
