UPS normally have 2 12volt batteries connected in series, so, you couldn't really use one in a car...
Well I might have a solution to the problems we are all having with getting a good signal to our computers. My problem has been that the modified sine wave from the inverter makes my screen flicker uncontrollably. I cannot seem to find a true sine inverter under 1000w and under $800. I also cannot find a DC ATX PSU under $150. So my current solution might be to get a universal power supply(UPS) and wire that up to the battery. I tried using the UPS battery hooked up to the ATX PSU and it seemed to work with no flicker. so now what i need to figure out is what voltage the UPS battery is and how to wire up the car battery to it. It seems as though there must be some form of inverter in the UPS that is of fairly good quality. So this is still inefficient in terms of converting DC to AC to DC again but it is a better sine wave. Let me know you thoughts and how i might wire up the car battery to the UPS. Thanks

They have 2 * 12v batterie? i havn't come across this before, but oh well.
you mite want to check out this link, may be exactally what your looking for.

They can have 1, 2, 3 or 4 (for big servers) batteries either connected series or paralell.
I have seen and fixed many UPS so i know what i´m talking about.
Have you seen Jeff Muchas PSU? It´s ATX and i think he is selling them at $90.I also cannot find a DC ATX PSU under $150
hey, the solution is quite simple!
I use a 300Watt inverter connected to a 315 Watt UPS. I just have to make sure that you never overload the UPS !! The power supply is therefore clean and regulated, and the computer is not having any stress at all.
By the way, anyone can tell me about any software for ups control? It would be great to set the ups to shut down the computer if the inverter is switched off, so that one switch can control the whole system!

Yeah, it makes PERFECT sense....
Not necessarily. The configuration of UPS battery varies widely. Some have a single 12V battery, some have several in parallel, some use 2 6Vs in series, etc. Totally depends on the size of the UPS. If anyone cares, all APC UPSs up to 500VA or so use 12V internally, so they can be used in a car.
