Eaton Powerware used to be Best, they made the very good FerrUps series.
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.
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.
A motorcycle battery... Good one, thx for the hint!
