Is the battery registration supposed to be for all battery changes? Or only for batteries that have different specifications?
I thought I was going to need to replace my battery because I had the radio on for an hour with the car not running, then when I went to start it later, the battery was dead. After a jump start, things seemed to be normal.
But I bought the Bavarian Technic tool and checked the battery voltage with that, which was good. So I didn't buy a new battery. That can wait. And I have the tool to register it.
Maybe if you replace a battery with an identical/near identical unit then the registration is of less or no importance?
