Has anyone heard of a product called "Battery Brain"? Apparently it's supposed to moniter battery discharge and disconnect the battery if it senses that it will become discharged. The "gold" version of this product is billed as a anti-theft device, as it also includes a remote control battery disconnect option. I'm having one installed on my '08 Outlook today,
as I like the idea of the remote control vs digging under the hood for a fuse. They are going to install it on the positive lead to the fuse box. </div></BLOCKQUOTE>

Have you anything to post regarding this addition to your tow? Yesterday the battery in my Acadia was totally dead and I had driven it just the evening before, parked it in our garage and when I went out to start it in the morning...nothing! Mind you, no accessories were plugged in, no lights left on, nor had I been towing it Reading on some of the Acadia forums, a dead battery is something many owners are facing; perhaps a Battery Brain might be a solution for us until GM gets their act together. And it would solve the issue of having to pull the fuse when towing in order to both prevent battery drain and accumulating mileage in tow for any of the crossover lambda SUV's (Outlook, Acadia, and Enclave). If possible let us hear from you. Thanks

None of these vehicles accumulate mileage when towing. The key is in Accessory and the speedometer/odometer is off. I've towed my Acadia over 10,000 miles now without a single mile on the clock.

Some "lambda" configurations have a constant battery draw down problem due to some feature that remains on when the key is off. See your GMC dealer - they should have info & fix for this problem is yours is on of the affected ones.

So far, I've only towed the car 10 miles from the installer to my house, so not much experience with it yet. I'll have more information after we leave for Arizona in January. What was done was to install a Battery Brain Gold or Deluxe version on the positive lead to the underhood fuse box. Then a lead was taken from there to supply a new 12V outlet to power the Brake Buddy. I do like the remote disconnect operation. It also has a manual backup for the disconnect in case the remote doesn't work. Also, I don't lose radio presets or anything else noticable so far, except to have to reset the clock. That kind of surprised me, I thought I'd lose the presets.

If this thing works as advertised, it would also solve your problem of a dead battery if something is inadvertently left on during normal day to day operation. It's supposed to monitor battery charge condition, and automatically disconnect if the battery is being discharged too low, and allow you to reconnect and restart it later. I haven't tried that option yet
