Battery tender

Does anyone have experience with using battery charges/trickle chargers to maintain their battery while the car is in "storage" over the winter? I've got a great trickle charger that I've used on my Audi for the past four winters. I attach the leads directly to the battery located in the trunk. I saw on another site that BMW recommends not attaching the charger leads directly to the battery but instead to some underhood connection point. Suggestions?

I use Battery Tender's cigarette lighter lead and avoid trunk/hood issues.

I purchased the BMW Trickle Charger while at the Dealership last month. The Service Tech told me to attached the alligator clips directly to the battery posts and to close the hood "one click" i.e, not completely.

If the Tech really meant what he said about attaching the charger clips directly to the battery posts he should have directed you to the trunk, not the hood.

Perhaps he meant the auxiliary jump start terminals in the engine compartment? The 12V power sockets in the cabin are a more elegant solution than popping the hood or trunk
