Kawasaki Vulcan 1500 battery size

HELLO: I have had my 1500 vulcan for 9 years now. It would be best to go to a dealer for the right battery, If you're thinking of a cheap replacement dont, they wont last. The last one i bought was around $ 118.00 from a dealer, its going on its 5th year. That is a big moter and it takes a lot of power to crank it over.
