I have a fresh new battery in the Shelby after the previous one started to fail.

My question is: Do I just disconnect the negative side cable (has a quick disconnect feature) and leave it till early spring and then connect up the battery tender to top up the charge, OR do I put the Genius (brand) Battery Tender on it as soon as I put it away for the winter and let it run till its ready to go back on the road?

I imagine that the amount (cost) of hydro used to keep a battery healthy via a tender is low.....but also know, that it won't take long to get it back to full charge if I just let it run a day or two before I'm ready to pull the car out of storage.

What I don't know is whether the battery prefers being trickled charged constantly over the winter.....or can simply be re-charged over a couple of days and be no worse for the wear....especially given its a new battery?
