4 times as long, give or take.... do note that car batteries are designed for high-current engine starting, rather than low current high drain amplifier running.

Keep in mind that an automotive battery is not designed for deep-cycle use, which is what you want to do with it. They are designed to output hundreds of Amperes for short periods of time, and then to be immediately recharged by the vehicle's alternator.

Deep-cycle batteries is what you want, as crutschow mentions.

Yes, and get yourself a good charger too! You don't want to spend money on a battery without the facility to charge it soon after use.

Of course, if you have a junk yard behind your house, you can get away with a used car battery. It just won't be the best possible thing for this job.
