R56 without IBS, still register battery?

[odie]

I have a 2010 R56 that appears to lack the IBS on the negative cable. My code reader shows no history of battery registrations since new and the battery AH set at 55ah.

When I bought the car a couple months ago it had a group 48 battery. Diehard 48H6 which from google searches is likely 60-70AH rating.

Should I bother to update the car or register it with my code reader to somehting like say 65AH or just leave it alone since there is no IBS on my battery cable?

I wouldn't bother, myself! Not sure it would change anything meaningful in a car without the IBS. And even if it does, a ~10 AH difference doesn't seem like a lot.
