Hi Guys,
I have a two car attached garage built next to my home. I however have three cars, 2005 X5 4.4, 2005 Audi (all wheel drive) and my 2003 M5 sedan. The first two cars will be parked in the attached two car garage. My M5 will be parked in an unattached garage, which has no electrical power/outlet, so I will not be able to use a trickle type charger, to prevent the battery from dying. What can I do other than detaching the battery terminals from the battery posts? Is there a way I can keep the battery attached and still prevent the battery from becoming drained and dying???
Last, I know I can go to the garage and start up the motor from time to time, but this isn't pracital or the best method, Im sure you'll agree.
Thanks for your input & replies.

In a word, no. Detach the terminals.

Robert, Park the Audi in the detached Garage, keep the M in the regular garage and all is sorted. I don't see the problem... ouich :cheers:

Seriously, while you will likely use the M5 less in winter, there are many days that you can drive it even without snow tires. Luckily we don't live in Alaska!!

So either way I see no problem. I think I might have had to leave my car parked in the garage all of 10 days total during a winter season. Took a cab when it was bad and drove it every day I could..

It only needs to be driven once every 5 days for say ... 1 hr ... to keep the battery in good charge, probably a little more in the extreme cold days..

Best wishes pal..

Have you ever had any problems with battery drains in the past?

No never had any draining problems/issues but then again, I never had my car parked in a garage without electrical power. I always use the battery tender during the winter but this upcoming winter will be different being that the M5 will be inside a garage without electricity.

Robert:

Pick up a large forklift battery, or other heavy duty wetcell, and use that to trickle charge the car. Bring the battery home occasionally, recharge it, then reconnect it to your car. How about a small solar panel from a marine supply? Small windmill? Use your imagination!

If you have access to sunlight, get a VW solar smart trickle charger. The ship with the cars and a lot of folks sell them on fleabay. Supposedly only charge to full and then shut off. Small charge, something like 1.8 miliamps (is that right all you EE's out there?). Cost should be in the $10-$15 range. It plugs into lighter outlet, so you may also need a lighter extension cord.
Regards,
Jerry

I agree with Andre. M5= most exotic car you have- it should go into the garage- is the garage heated? Put the Audi or X5 in the unpowered garage. Or- get an electrician to get you power out to the unpowered garage- and get a heater too.

Drop a line to the garage- by the time you spend money on a forklift battery or a solar panel your half way there... plus a permanent 110V line adds value. Dig a 12" trench, drop schedule 80 PVC conduit, drill a few holes, ...sounds complicated but it is very easy.

Of course if it is 500 feet away, different story!

To Ard & other members.......
thanks for your replies and possible solutions but the distance to run an electrical line is just NOT possible. Unless anyone else has any other ideas looks like I'll have to just risk it and let the car be and start it up from time to time and hope this is good enough. :sad2:

Robert - just don't forget about the wear and tear of a cold startup on an almost dry bore coupled with the buildup of water in the oil is not a good thing. When I've stored the M3 similarly, I've periodically just sat in the car and listened to a cd in the car while maintaining an engine speed of above 1,500 rpm for about 15 minutes. Boring, yes, but useful to get the oil good and hot and evaporate out the accumulated moisture to eliminate any acidic combustion byproducts..
