A fully charged battery should be 12.7 volts (disconnected, as especially on modern cars, without a proper ignition switch, circuits can become live from just opening the doors)
A "flat" battery is ~ 12.1 volts, but as I have found, the NG starts fine when the battery shows an indicated 12.15v. It's those live circuits
I have replaced the battery on the TTiD. Voltage seemed fine, but the cold cranking amp test showed it was on the weak side. The car now starts better & I have another emergency battery that is too good to weigh in, but not really reliable enough for going away on long journeys with
