Battery charging

[rwb]

What about getting one of those standby battery gadgets that plugs into the lighter socket while you disconnect / charge the battery?

(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.

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

...A sealed one can explode if incorrectly charged where as a valve regulated one will vent hydrogen gas, like the Hindenburg.
