Those with 981s. Do you notice 'high' readings circa 15.3 volts as a matter of course? It then falls to 12.6 and stays for a while before retirning to high ish readings after load has been applied.
Battery is fully charged and displays no sinister characteristics.
Asked the same question to Porsche technical support on-line as mine does the same, they reckon its OK, though I was going to get the battery checked by the local OPC as a precaution.
