1999 BMW 323

Electrical problem
1999 BMW 323 6 cyl Two Wheel Drive Automatic 129000 miles

This vehicle and my 2006 Honda Odyssey:

Both batteries died today, first the BMW at 10am then my Honda at 8: 30pm. Garage kept at my home (concrete slab) built in 2007. I keep the vehicles clean and regularly serviced.

I have no changes to the environment EXCEPT unbox a metal shelf that are grates. 64in x 35 in that is 15 ft from the BMW trunk. 5 ft from the Honda battery.

I have parked the Honda in the front of the house and moved the BMW to the driveway.

Am I to assume that an electro-magnetic field is draining my batteries? How can I test the theory?

Hi there,

I would investigate each car individually, do a load test on the battery after it is fully charged and do a current draw test, start here.
