I purchased my 2005 Roadster a couple of weeks ago and have gotten a great deal of help from this forum which I reallly appreciate. My next concern is that I've noticed the battery in my car is not the right size. The previous owner has replaced it with a much shorter battery and of course I don't know the age of the battery. Can someone advise me on the best and correct size battery with a good price to buy for this car? Thanks in advance.
