Technically, the replacement size is 124, although many internet forums seem to say that he more common size 24F is an acceptable replacement, FWIW.
Look on the battery installed to see what size it is. Ask any parts house. Look at Walmart's battery application book.
Somewhere in my search for a battery, I saw a reference to Interstate Battery- MTP-91. Lo and behold it was the right size!
I have a 2009 model and it has a 12 volt 6.5 amp battery.
