Been reading the "CVT 10-15MPG" thread and some opinions on replacing / using "the small battery" aka the 12 volt battery under the hood. This has me curious about a couple of things...as I understand it, the 12V bat. is simply a redundancy for the 12volt starter incase of IMA battery failure but supplies no real power to the car or on-board systems? And definitely supplies no power back to the IMA system?
If that is the case, has anyone actually had to resort to this for "emergency" starting?
If you were going for ultimate MPG what would be the effect of disconnecting / removing the 12V bat and starter? A couple dozen pounds of weight and less electrical drag?
If both batteries were somehow dead or nearly dead would it still be possible to push-start a 5 speed like a normal car?
Just letting the mind wander a bit
