As judges we've discussed that we should be deducting when we find an incorrect sized battery in a car similar to what we do on just about any other piece attached to the cars. For some reason, in the past, have chosen to look the other way and now it seems that a small deduction (as would be expected in the weighted scoring method) is appropriate and might help motivate owners to call more and in turn influence the makers as they have been in so many other reproduction part examples.
