What is the general rule of thumb about using battery backups and surge protectors?

Is it wise to plug a UPS into a surge protector? Is is wise to plug surge protectors into the battery backup's outlets?
 
You can do either of those IF the load on them does not go too high for whatever they're plugged into.
 
On every manual I've ever seen on UPS systems they all say something along the lines of:

Don't daisy chain to or from the UPS. It should be plugged in directly to the wall.
 
That's for people who would plug a UPS into a UPS or put chains of several power strips and UPS and stuff.... Pretty much just use common sense (which is not so common, especially with electronics) and you'll be fine.

I'm not recommending you DO it, though. It's still better not to.
 
Yeah I don't really see the benefits of "over-protecting" yourself in that sense. I don't think it would really make much of a difference either way....

It's not useful for more protection. I was thinking more if your UPS has 4 outlets (like my Liebert) and you want to plug in a ton of small stuff like clock, modem, router, phone, etc... then plugging a power strip into it is fine. Just don't run like 20 computers from it, y'know?
 
Really, I'd see no problem with plugging one surge protector into a UPS so you have room for lots of low power peripherals as long as the max combined wattage doesn't overdraw the UPS. I'd be real careful of what all get plugged in... avoid laser printers, etc.

As for the other way, it all depends on the circuit and the rating of the surge protector. It would be fine unless multiple UPS's put to much load on the circuit or through the surge protector. ... or so i believe anyway...
