I wouldnt go the car battery and inverter route. The solution seems silly to me, just go any buy a UPS.
What exactly is so "silly"? I am a DIY. I built my own computer and I fix my home appliances myself.
A UPS
IS a
battery, an inverter, and a charger built into an ABS case. You are paying top dollar for them to put it all in one case. A true UPS runs off the battery through an inverter (many are not pure sine wave that is why you can't run a laser printer) and is a clean power source. Only you get a tiny 12 volt battery that lasts only minutes when the charger loses power. A deep cycle car battery would last many hours.
Hehe googlesearch:

This would be an expensive battery back up (below) but a poorman's true UPS could be a power inverter here

CR Inverter/Charger
Affordable backup power solution
The entry-level CR Series provides AC power without interruption to keep your critical equipment running during a power outage. Built with an automatic transfer switch, t
he CR instantly switches to battery power during a blackout or brownout. When AC power is restored it automatically recharges the battery. Available in 1000, 1500 and 2400 watt models, it is ideal for powering common loads such as refrigerators,
computers, lights, small televisions, radios and fans.

connect as many batteries as you need.
Features
* Automatic, fast transfer ensures no intermittent loss of power to your critical loads
* Built-in battery charging ensures batteries are fully charged and ready to use,
while protecting them from being overcharged
* Low and high battery voltage and overload protection circuitry
* Audible alarms to indicate low battery voltage, overload, and fault conditions
* Front panel LED indicators to provide status-at-a-glance

The TrippLite SmartPro 1000LCD is classified as an UPS.
According to tigerdirect and by definition, if it isn't using the battery as a constant source, it's a "UPS battery backup" There is no switching to another power source with a true UPS - hence, no interruption.
