Just curious, is this because you drive your car infrequently or is there a benefit to the battery? I have never used a charger before on a car that I would drive at least monthly, but did keep my motorcycle on one through the East coast winters.

Keeping a battery on full charge with trickle charging along with desulfating/conditioning the battery are always beneficial to the battery. Most car nowadays are electric hogs. E63's battery is never fully charged even if you drive it daily. If there is an easy connection, might as well hook it up daily.
I have one of these exact chargers connected to my motorcycle battery. It treats the battery very nice.
Still running the original OEM battery since day 1. For reference, I bought the bike in April of 2008. That is a LONNNG time for a motorcycle battery.
If it is in the hood, perhaps I can hard wire the connection and fish the wire out?
Which points do I connect to?
If you cut a notch out of the flip-up cover (on the near side only), you can attach the alligator clamp to the + charging post and close the cover. Then the clamp doesn't interfere with closing the hood. I can take a picture if my description isn't clear enough.
