Powering Home Electronics Using a Car Battery?????

I have seen some folks at tailgates that use regular car batteries to run a TV and Sat receiver. We have been doing so with a generator for about 3 years now, but this year I want to try something different. How would I go about using a car battery to accomplish this? I am guessing I would have to get an inverter and do it that way, but the battery will eventually die down and I have no way to recharge it unless I keep switching out one battery from the car with the one powering the equipment. is there any other way to do this?

A dual battery setup may work best, Make sure you use a Battery Isolator that way you won't drain your "start" battery. You can pick up decent isolators from any RV center.

Run the invertor off the second battery,

Just my two cents...

I've got a crappy inverter, only 140watts(but free). I have the inverter mounted under the hood. It's powered remotely by a switch on my dash. I've got wires running from the inverter to an outlet on a lower section of my dash(below where the old speakers were, it's black). When I get a better inverter I'm going to run romex wires and I'm going to put a second outlet(outdoor style with waterproof cover/seal) at the back of the bed. Here are the pics. Oh yeah, don't mind the cable ties holding the inverter. It's just a temp. setup until I get a better inverter.

in our quad trailer weve got a sweet setup. Me and my dad built a bathroom in it and put lights in and stuff. To power it we use a 2500 watt inverter hooked up to 6 golf cart batteries. We used the golf cat ones because they are deep cycle and last a long time. The batteries are only 6 volt though so you have to hook 2 up in series and then hook them to the next series in parrellel. Anyways it works good and the batteries are charged by my dads truck when we are pulling it.

Read and learn, padawan.

I would recommend a Pure Sine Wave inverter if your primary loads are going to be electronics. Square, and Modified Sine Waves can induce signal 'noise' in home entertainment electronics.
