I was wondering..... Is that a factory made connection? Cause there are holes for the screw and nut on the sides of the post. Could someone have modified the posts and drilled holes into the top to accommodate the fit?
Looks like what my mower uses. I get them at Advanced Auto. Take you old one with you so they can match it up. Be advised, these batteries are NOT cheap either. Good huntin'.
Jbh3 has a good point about taking your old batt with you.
Just a reminder - they will also charge you $5.00 or more core charge for the new battery. emoBang Turn in the old one to save you that extra 5 bucks or more. emoSmile
