Brand new battery drained

Unfortunately it is that high and I agree it is higher than I would expect/want it to be.

From and analysis I did a while back:


In doing some measuring of current draw of various things while the ignition is off I found the following to have the most significant draw while powered off:

ECM: 50mA
Body ECU: 100mA
Radio: 5mA
Clock: 5mA
Keyless Entry/Remote Starter on my 09: 150mA
