To use a car analogy, it's like rotating your tires. The front ones get more wear since they are the ones turning the vehicle. To even out the wear, you move the front ones to the rear and vice-versa. If you don't rotate, then your front tires are gonna live a shorter life than your rear ones.
Same thing for batteries.
