I could be wrong, but it's my understanding that it's to maintain a battery, to keep it charged - especially if you store your car for long periods of time, like me. I just stored my car for the winter, so when I take her out next spring, I don't want a dead battery. The tender only charges, when the battery starts to get low. It flashes a red light while charging, and then goes to a solid green light when fully charged, and goes to standby mode. Or so this is my understanding of how it works.
