Re: UPS battery replacement causes an . . . interruption

 Understood.  My point was that if you did have a generator then the UPS would only need to run for the length of time that it would take for the generator to kick in and switch over.  That would likely be less than a minute.

Yes it is "planned" but I'm making them do it at 6:30am.
