Having the opportunity to use all sorts of brands and types of batteries, when it came time to sell a particular brand, it was a no-brainer that we'd be handling Interstate. Basing our decision on quality, selection and price, Interstate was the hands down winner in all categories.  Typically we experienced the life of other batteries not exceeding an average of 2-3 years under heavy use, winching and cold weather operation. Almost every premium Interstate we've had the opportunity to use, we've seen upwards of  5 years, & some almost 10 years old and still operating at their peak performance!
