BMW Motorcycle Battery Tender for My G650GS

BMW Advanced Battery Charging System

My story with the BMW Motorcycle Battery Tender started after a recent problem with loose battery leads from an improper new vehicle preparation. And in any case, I needed a practical way to properly maintain the battery on my new 2010 BMW G650GS Motorcycle which I’ve been accessorizing.

So after much on-line research, it turns out that the battery can easily be be trickle-charged though the Powerlet jack located on the left side of the pseudo-tank (the real gas tank is under the seat). Nice!

To that end, I picked up the BMW Advanced Battery Charging System (Generation II), yesterday from my local dealer, part number 72110419496.

The nice part is that the battery connection (the DC end) is a generic heavy-duty connector, and that the package comes with three modular ways to connect up:

  1. Powerlet male connector
  2. Alligator clips, with in-line fuse
  3. Battery terminal connections (not really needed if you are using the Powerlet connector), with in-line fuse

Looking on the bottom, it looks like this is an OEM product of Deltran (looks like their Battery Tender 021-0128 Battery Tender Plus 12V Battery Charger). It’s my guess that there was no point in BMW designing their own for this mid-range product. And, it was about the same retail price as Deltran’s product.

Well, I was pleased to see today that the battery was fully-charged and my G650GS started right up. Highly recommended.
