Battery should be about 12.5 v when engine is off and 14v when the engine is running and battery is charing.

2 things to check...first is the alternator charge which should be around 14.5 volts on idle.....

Sounds like the alternator is OK, over 13.5V is considered OK. It will vary depending on load and rpm.

If your only getting 12night after a drive its time for a new battery. |

@suggs, a fully charged battery should read 12.6 volts, yours has 12,4 so its not far off....i should think a longer journey or a bench charge should be enough... ... - .- -.

I've decided it's just part of ownership. Mine didn't start on Sunday after a cold night and not being used for 3 days. Put it on charge for 6 hours and it was fine. I've learnt to live with it....on a plus side, was away with tintent the wknd before and the Japs/Koreans got stuck.....I didn't and took it with grace and dignity Is this where I put the car details and a bit about myself ?........ |

You can leave the leads on, just make sure the ignition if off.
