While your expectation is a logical idea, the fact remains that the "baseline" of a good battery needs to be clearly and consistently defined. Does 281 GIDs (I forget what the actual number is) represent the reference baseline?
I think your question actually raises a concern that I have:
Will the software update simply alter the algorithm of how the battery capacity is calculated/displayed given the existing state of the battery? I am not sure how to describe it but it's akin to software made to hide the true health of the battery.
281 GIDs = 12 bars
250 GIDs = 12 bars (after software update)
Surely you wouldn't want to purchase the vehicle with the lower GIDs even though the battery meter indicates full capacity right?
I dislike the idea of this software update made to "mask" the true health of the battery. If the battery does not measure 281 GIDs, it should be warrantied by Nissan. Period.
