You know what this thread needs?

MORE PUNCTUATION1!!!1&%!*&1&!&++

Seriously though, the battery should have at least 12.0 volts with no loads turned on and the engine off. 12.4-12.6 would be better. With the engine running, you should see 13.6-14.4 volts. Anything under 13 while the engine is running means the alternator is probably bad. Or there could be a loose connection or bad ground.
