(Never tried myself, but I hear they work).
Hello? What's this?
(I have a 307cc to look after (absolute piece of shite) that has a mystery battery drain.)

A good battery should measure 12.6V. With the engine running you should get over 14V.

Current: 407 2.2 HDi 170 & C6 2.7 HDi.
Former: 406 1.9 TD; 406 HDi 90; 407 2.2 160; 307cc 180; 508 HDi 140.

A fully charged lead acid battery should give 2.2 Volts / cell or 13.2 V
Fully discharged is 1.9 Vpc or 11.4 V.

I agree, you want to be seeing 14 - 14.5 V with the engine running on conventional charging systems like the 406's
Some of the newer 'smart' alternators will kick out up to 18V
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)
