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
