Dead Battery....Help!!!

Does anybody know what type of battery I need or is it worth just jumping the car from my saab?
Also will all the settings have goe from the car? radio etc???

After the battery is ok...then test the charging system and for a draw
As the car should be ok if it sits for 10 days my car will start after a couple weeks
hope that helps.
I called the AA out and they got the car going again...could be the cold!!
Im putting it up for sale this week so I didn't fancy getting a new battery for it!
Its running fine now and its gonna break my heart selling it as its the best car Ive driven.... but no job = no 381bhp super car!...Gutted!!
