RTFM ... Should be in page #246 in your Owner's Manual ... the same location where the jumper cables go under the hood.
In case your car didn't came w/ a hard copy of the manual you can view it online in PDF pg #248 from http://www.5series.n...s_Manual_US.pdf

8 weeks is a long time for a tender/charger to put even 1 or more amps into your battery. The better
sytems cycle off when the battey reaches a certain voltage or charge on a time cycle.
Make sure you don't overcharge the battery!
The hood up with the switch activated will be fine.

Get a wall outlet timer and plug the battery tender to it ... program it to turn on for 12 hrs once a week or 6 hrs every 2-3 days.

If your battery tender is smart and puts out only enough current to keep the battery topped off.
8 weeks is a long time for a tender/charger to put even 1 or more amps into your battery. The better
sytems cycle off when the battey reaches a certain voltage or charge on a time cycle.
Make sure you don't overcharge the battery!

Oh...and mine is a Deltran battery tender...when attached to the car...it stays plugged in all the time. I use the same thing on my 911 and it works great...battery in it is going on 9 years. By far the best $50 I've ever spent
