There always exceptions based on personal opinions, experiences on batteries. There is no right or wrong views. Personally I replace batteries after 5 yrs. rather than wait until you are on the road RVing and have the battery go dead and then have to run around to find a battery replacement. I have the same rule for my tires, replace them after 5 yrs. for the same reasons. Waiting for a Good Sam tow truck to come out and change/replace a blow out is not my first choice.
