I know this may not pertain exactly to camping question, but since there's so much knowledge here and there's no difference between a camper battery and car battery, I thought I'd ask. Going tailgaiting this weekend and was wondering how long my 13" TV and Satellite Reciever would run off my truck battery before I need to fire the truck up and charge it back up? Those are the only two things being used.

Not very long. I would start up the truck every 30 minutes and hope for the best.

OK, so instead of just correcting me, how about enlightening me with the differences?

Good point. The battery in your truck is designed to satisfy a high load for a very short time- the starter motor. A battery in a camper should be a deep cycle or designed to satisfy low loads for a long period of time, such as the interior lights in the camper. The interior design of the batteries is different.

Car "Starting" batteries are designed to deliver high current for a very short period of time, camper batteries should be "Deep Cycle batteries" which are designed to deliver low current loads for a long period of time and can safely be discharged to fairly low levels without damage. Most of the so called deep cycle batteries available are really combination starting / deep cycle batteries. About the only true deep cycle batteries are "golf cart" batteries which are usually 6 volt so you have to use 2 hooked in series to get 12 volts. The battery that usually comes with most RV's are the combination batteries. HTH

Simple explanation... Car batteries are designed to provide high amperage for short duration (starter motors draw big amps, but, not for very long. Batteries used for campers are designed to provide relatively low amperage over a long period of time, i.e., 12 volt appliances and lights are low draws, compared to your starter, but, run for longer periods of time.
Two different purposes, two different designs. You want to use your "sprinter" battery to run a "marathon" device. It can be done, but, it isn't very efficient or good for the battery.

Forgot to add the construction is different in that true deep cycle batteries have heavier plates.

Link here. We use 2 6 volt golf cart batteries in series. I prefer the heavier plates, closer to true deep cycle. Do not discharge your batteries below 50%, about 12.1 volts. Read the link above, lots of great info there. You'll learn lots more than we can tell you here. Come back here and we'll all talk some more.
