Circuit breaker installation on Mini Cooper 2001 to prevent battery 's dead
 

Hi all,
I've been having electrical problems with my Mini Cooper (year 2001) for the past year. Everytime I dont drive it for a couple of days, it turns out the car battery is just dead. Obviously there is some elctronic device still pumping off the battery after I shut down the car.
I took it to a garage and it changed the RPM monitor display part, but the problem is not resolved, there is still something causing my battery to be dead.
My question is : CAN I PUT A MANUAL CIRCUIT BREAKER TO RESOLVE MY ISSUE SO I DONT HAVE TO MANUALLY REMOVE ONE OF THE TERMINAL CONNECTOR ON THE BATTERY ?
Thanks for your help, maybe someone out there already had the same problem.
Cheers

I would NOT recomend this, You can loose memory and have to have the car reprogrammed at the dealer. Also loose any updates that were done.

FIND the problem yourself take a digital ampmeter and install it on the positive line between the battery and the + terminal. Look at the readings , Then start pulling fuses one at a time and observe readings certain accesories do pull some amount of current . likely you have one item pulling large current to kill the battery that fast. Likely several amps.

The other better quick fix is install a battery tender to keep the battery charged while sitting.
