Use a multi meter and check the voltage of the Cap. If it is above 12V then your good to go..

Shorting the type of cap that we use for car audio will not damage it - well other than the big black marks and potentially some metal loss on the terminals
Not that I was serious in the first place.. If you want to waste your time checking it, I would charge it up to 14.5 volts and, as Haunze said, let it sit disconnected and measure the voltage after a few days. It shouldn't drop more than about a volt a week.
