A real UPS

By Wilbur Corncob at 04/08/07 09:26

I hate UPSs, they are a necessary evil, but usually run out battery power way too soon, and the included batteries often lose their viablity after a year or two.

That's why I like this Austrialan's website:

Upgrade your UPS! (with some car batteries...)

If you've got a UPS that runs from some variety of gel cell that you can't easily buy locally, the odds are very good that it'll also run A-OK from some other lead acid battery with the same terminal voltage (which almost always means one 12V battery for smaller UPSes, and two 12V batteries in series for bigger ones).

He explains the options for using various batteries including car batteries on your UPS.
