I know this is an older thread, but I believe my battery is on the way out (gave me a service warning, clock is losing time, etc).

Is the only downside to not "registering the battery within the DME" that the battery may fail prematurely (3 years instead of 4)? Any negatives on the car itself or electronic system outside the battery in not registering a new battery?

I ask as I can go to Advanced Auto and pay $140 and install on my own (and have a multi-year warranty for if it fails) vs. paying $450+ at the dealer inclusive of the re-programming.

Thanks.
