I got a new battery today,I didn't drive it for 2 days and it was completely flat no lights at all,I think I must have left the rear park light on.Put it on a charge and the gauge didn't move at all,Left it on over night and it was still flat.So went to my Suzuki dealer a picked up new battery for $68,And its the right battery no messing around or anything.I bought the 2006 new in 2007 So battery was somewhere in the 4 - 4 1/2 years old.
