What is the "shelf life" of a new Porsche Battery (PN 999.611.075.07)? I recently bought one since mine appeared to be getting weak. However, after leaving the Battery Maintainer plugged in for a week and a little driving the battery now seems fine. How long will my new spare last sitting on the garage floor?

Thanks.

Unknown, but would probably not go over a year.
