Got a new varta battery on Friday and put it in my Peugeot 306. Been using the car to commute from Leicester to Donington. I’ve been checking the voltage of the battery after every journey and it keeps dropping, Today I checked the voltage of the battery and it reads 12.2 and the green indicator light has gone out on the battery meaning that it needs to be charged.
With the car turned on and revved the voltage only increases by 0.2 – 0.5v hitting a max of 12.7v if lucky.
Don’t have a clue as to what’s wrong with car but I know the battery is not charging as the drive to Donington is a 45min drive.
Anyone have an idea on what’s wrong?
Charging System Problem?

Hi,
As you know, your battery isn't charging. It has to be either dodgy alternator, or slipping belt, which will usually shriek badly, so I doubt if it's that.
I think you are straight into exchange alternator territory, but check your connections to the alternator first, and connections between alternator and starter.
When revved a little bit, say 1200 rpm, you should be getting close to 14V on the battery, so that's your problemo alright.
Bad luck, but should be an easy fix.
cheers
