Stopped by AutoZone today to 'donate' my used oil and asked if they carry Interstate batteries as it may be time to get a new one before next winter season - the sales person told me that all of their batteries that they buy are from Interstate so they are all Interstate with their own label on there - DuraMax (or something like that) - is this really true?
