I have removed the neg terminal on my C6 battery every winter, sometimes 3 months pass before I restart it and it will need the window index, but nothing else happens and starts perfectly even after the 3 months no power....
There's some discussion now on battery disconnect versus trickle (smart) charging.
It would be nice to know what's best or whether both procedures are acceptable.
I've been told and believe I've read somewhere in the owner's manual that long term storage requires a battery disconnect, so it seems that way is what the factory wants.
I personally have read that corvettes now have so many live circuits in them that any length of time unused would quickly drain the battery down and possibly ruin it -- hence the recommendation of disconnecting.
I'm also thinking that trickle charging would be as good or better for reasons stated and a little more handy.
BTW- I keep mine on C-Tek trickle all the time -- summer/winter/storage/daily -- I like to keep my battery at optimum all the time.
I'm lucky in that my 'vette is garaged and connecting a charger all the time is very convenient for me.
Whether it's actually necessary is another matter but I believe that if you maintain the battery this way it will not hurt it but help.
I'm hoping that we can start another thread on the subject and get some empirical info from those in the know or in the industry to give some direction.
I think we'd all like to do and know what's best for our cherished corvettes.
Cheers,
Colin.
