That means the difference between a 90 AH & 100 AH battery (all things being equal) is that under the same circumstances, the 1st battery will die a bit quicker than the 2nd.
Again, amp hours is only a rating given by a battery manufacturer that describes a battery's capacity of how long it will run before it is drained down. I have no explanation as to what you read as to why a 100 AH battery would be bad for your e53 versus a 90 AH battery. Perhaps they have a different understanding of AH (amp hours).  |
Agreed. You would definitely want to get the largest Reserved Charge (RC) and Cold Cranking Amp (CCA) that will fit. In this case, the 100AH battery would be the better battery given the aforementioned choices. I'm not sure why you want to go with a lesser specs battery.
BTW...there is no battery registration on our E53. Battery registration only applies to the newer models.
