I measured my "cigar socket / outlet" with a multimeter. Instead of 12v it had 19v. Is this normal? Is it my voltage regulator, alternator, battery that has problems?

Car: Peugeot 307, 2.0 XSI 2003 The 12v "cigar socket / outlet" is off when my key is turned off, and on when I turn it on.

Additional information: Battery is almost 1 month old. Mechanic replaced it. 

Voltage car off with key not inserted
Battery -  12v socket
16,67v     0v

Voltage car off with key turned 2/3 steps
Battery -      12v socket
not tested     18,2v


Voltage car on
Battery -  12v socket
20v        20v


Voltage car, airco, headlights on
Battery  - 12v socket
20v        20v

Went to the mechanic, and the voltage looked good at 14,4v +- when everything (car, airco, lights, radio) were on. Looks like my multimeter is busted. Need to buy a new 9v battery for my multimeter to test if that fixes the offset, or I'll try to calibrate my multimeter.

Anyways, always test with another multimeter if in doubt.
