However, in some cases it's cheaper to just get a whole new UPS... 8-/
I know I was shocked at the price I had to pay last time I replaced the APC battery. My favourite vendor sells a lot of Liebert PowerSure UPSs, so I presume they have had no problems with them, or they'd have given up by now. There is a large range, and the prices are good, but the only thing I can say is that I haven't heard anyone complain. I'd prefer to hear a positive
report
before buying.
Did you check Eaton Powerware? They are very competitively priced IMO. We bought APC's before as well, but I felt the controller software was not as smooth as it could've been and the battery replacement-programs very not that good as Powerware's variants.
With UPS's I prefer a brand-name. If nothing else for the reason that they stock batteries even to older models.
Never heard of them, but I'll take this as a recommendation, thanks.

Eaton Powerware used to be Best, they made the very good FerrUps series.
Re: batteries, most all UPS's I've seen use various standard VRLA batteries (Valve Regulated Lead Acid, often mistakenly called Sealed Lead Acid, or Gel Cells), readily obtainable from vendors like www.digikey.com, assembled into packs... with a few exceptions, you can use the generic equivalent battery, much much cheaper. I resurrected a dead SmartUPS 2000 that was going to be tossed at work by replacing the batteries with 4 x 12V20AH Panasonic VRLA, which happens to be the same size my motorcycle uses.
Now, battery prices have gone up considerably these last 2-3 years, lead prices are very high, as are transportation costs.

Marking words: "used" to be best? Which is the best now then? APC is apparantely not an option as they suck bigtime IMO, so what's? Powerware and APC are the two biggest and most wellknown UPS-manufacturers I know of.
