Re: Use of battery maintainer ???
Definitely leave the battery in the car and attach a battery charger with a floating ground. The Battery Tender is an excellent model, but there are many other's out there now that are just as good at a fraction of the cost. I put mine Crossfire in storage every year and use a floating charger that I purchased at Harbor Freight for $6.00. Since you're putting your car into storage be sure to put Stabilizer in your fuel, rubber under the tires so the don't draw moisture, and it wouldn't hurt to raise the weight off the suspension.
