Note for next time you post pictures or an instructable: Rotate pictures so they're all right side up. Although, it gets more people's attention when they're not :)

I don't know about your home owner's insurance, but ours is null and voided if we were to have any kind of automotive battery inside the house.

good idea.i used a 2000w power inverter and an 18v truck battery.

Cool instructable but instead of a car battery use a Deep Cycle Marine battery, these are meant to be deep cycled where as a car battery is meant to be used only for a few seconds to start the car, and they arent under a constant load. A car battery will work but it will wear out faster

Data loss could occur if your PC disconnects from the battery accidentally just as it would if it suffered a blackout while connected to house current.  Make sure the clips make good contact, or better, use screw-on battery terminals available for a few dollars at auto supply stores.  At best, this is a good emergency or campground setup.  
Also, any good photo viewer, even the free ones, will allow you to rotate and save your pictures before downloading them.

If you are going to use a car battery, and lay it on its side, make sure the battery is designed to work in a position other than upright (vertical). Many car batteries are designed to only in an upright position and not work properly or worse, may leak battery acid.

this battery is different its sitting upright the connections are on the side the wires to the car are bolted onto the battery
