My Corvette battery lasts longer when it stays at the right charge level instead of going dead and getting recharged over and over. A Battery Tender gives me peace of mind because I know my car will start when I want to drive it, without the frustration of a weak or dead battery.
For me, using a Battery Tender is also about protecting my investment. A Corvette is more than just a car to me, and I want to keep it in the best condition possible.
