Battery Cutoff Switch

I need the best battery cutoff switches I can get for two cars that are left idle for a few months at a time.  I have a 2001 Mercedes Benz S500 and a 2002 BMW 325XI where they must be installed.

Best source for reliable battery cut-off switches I know of would be any speed shop that deals with drag race cars. Most "doorslammer" race cars, (bracket cars through pro-stock) are required to have these switches mounted on the outside of trunk lid... Of course, you can mount them inside the trunk, or anywhere else you wish!

Buy a battery cutoff switch for a few dinero. Install it on a battery post and connect the battery cable to the switch. It also serves as an anti-theft device for when you must leave your car at the airport or in southern Arizona.

Pulled out the dash fuse to get the draw out of the battery, i have no dash gauges.what could be the problem

Replace the dash fuse. If the draw on the battery is a big deal, invest in a cutoff switch so that the battery is not being used when you don't want it to be.

Your local auto parts store may or may not stock them.

2004 porsche boxer Why does the battery go dead after a month of no use?? the battery is new: My other car can be left idle for 2 to 3 months without a problem

All modern cars have a natural current drain; it's part of having an alternator. In today's vehicles, the parts of the alternator remain energized, as well as a certain few accessories, including your computer. A recommendation: if you aren't going to be driving your car for at least 2 weeks, unhook the battery, or install a battery cutoff switch. This way you don't kill the new battery. Your other car is likely a stroke of luck that enables it to last as long as it does.
