Several other things to reset after a new battery, like the radio, but I am not aware of any adjustment to the alternator.

He opined that the alternator might be running too hot, that with the old battery it could have been trying to run a higher voltage because it wasn't charging well.

If it's still showing a true 16v at the new battery when the alternator is running, I'd be inclined to take the alternator in for testing.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi, I have an '04 996 C4S that doesn't get enough regular use and sure enough its 7 year old battery died. The AAA battery guy measured the alternator at 16 volts. He opined that the alternator might be running too hot, that with the old battery it could have been trying to run a higher voltage because it wasn't charging well. I doubt these things are that smart but then again, chips are everywhere in cars these days. Does the alternator need to be adjusted or reset in some way with the new battery. Thanks RamV

Thank you, will call the dealer.

Did you fixed your charging issue, if not try doing a vehicle handover.
