Why does the battery in my car go flat after a week if I don't drive it?
The battery in my Peugeot 308CC was draining frequently, especially in cold weather. I replaced the battery seven months ago but it still goes flat after a week if the car isn't used. Peugeot dealer says to drive it more often. Cannot help but think there's an underlying problem with this cars electrical system. Can you offer any advice?

Yes, there will be and because the battery has already been drained so often it will have lost its capacity to hold a full charge so will only get worse. Call in a local car electrical specialist. Possibly something to do with the roof mechanism. A fault with the interior light switch would drain the battery overnight.

I've just bought a used (2004 model) Range Rover and heard beforehand about a simple fix to stop the battery draining every couple of days or so. I've had a "hedgehog" or "Porcupine" fitted in the heater...
I own Ford Galaxy 1.6 Titanium X (2012 model). It has suffered from battery drain since I bought it in 2013 and the problem has never been solved. Any idea what could be causing this?
Why does the battery on my Peugeot 306 go flat when the car is left with nothing running? The battery has been checked and it's fine.

Much improved over 307CC. Reasonable range of engines and transmissions.
