I buy my UPSs on Ebay for **** all then buy new batteries for them.
I am full up on UPS units. My wife brings the dead ones home from work
and it is usually just batteries. They do not even try to fix them
there.
Ssssh! Don't let it get out. That may dissuade them, then where will be.
I've got a handful of APC Back-Up XS 1500's doing a wonderful job of
keeping all kinds of stuff up and running and provided pure power.
Thanks to a client who refuses to replace batteries rather than UPS's
I'll never buy another UPS unless I'm unfortunate enough to take a LOT
of lightning strikes that blows them up.
You've gotta love people with more money than brains!
Inly problem is, a "backUps" does not "provide pure power" as it is a
"standby" unit. All it gives you is "filtered" power like a good power
bar.
I've got a smart-ups. How pure is the power from that?
I'd guess it a modified square wave which means it's a square wave pretending to be a sine wave. Most modern electronic gear doesn't care about the waveform as long as it's being fed alternating current. ヽ(ヅ)ノ

I do notice the lighting (mostly LEDs) changes brightness slightly when it switches to battery. There's also a slight dip in brightness every second, so it's not that even an output. But the main thing is I lose less LED bulbs due to the excessively high voltage I have here, as the smartups drops the voltage with a transformer as necessary. 256V when you're meant to get 230V is rather ****.

If I measure a voltage out of my outlets at home that's too high, I can call the power company and they'll send out a tech who will check the voltage and take action to correct the problem. Most of the transformers around here have selectable taps that the power company can change so the voltage supplied to homes can be adjusted so it falls within specs. If I saw 256 volts across the phases at my home I would be a bit concerned but if I saw 265 volts I'd call my power company. As I recall, the last time I measured the voltage across the phases at my home, it was below 240 volts which means there was just under 120 volts at the standard receptacles. That was three Summers ago when the central AC was running. None of the LED bulbs I've bought have failed but a lot of the CFL lamps I've owned have died. I think it may have to do with whether a lamp is rated for base up or base down operation. One of my desk lamps at home has vent slits at the top of the bell shaped reflector and the CFL lamps lasted longer in that desk lamp than in the other desk lamps I have that aren't vented. All my desk lamps have LED bulbs in them now and are barely warm to the touch with the bell shaped reflector pointing down. ヽ(ヅ)ノ
