i have C-Tek maintainers for our cars. With our old Chevelles, I just disconnected the battery in the fall and hooked it back up in the spring. Batteries last me 7-9 years on average. With the constant draw from the computer system in the Corvette, you will definitely need to disconnect the battery or use a maintainer. Whatever, i just connect the maintainers and let them do their job. Can't hurt I guess. We'll see if these batteries last any longer with the maintainers.
