I have my batteries tested yearly. They do degrade, but not to where you can go out to start your vehicle, and it turns over slowly before it starts, and you know you have some time. When one tests marginally, I replace it. The cost of a battery and the worry for loved ones stranded by something as simple as a yearly test is meaningless, compared to a hundred dollars or so for early replacement. Which reminds me it's time for some battery checks.
