Hi there, has anyone else found that their 147 appears to get about 18 months out of a new battery before it needs replacing? Mine has had 2 batteries in nearly 3 years. Car runs well with no known faults although it does do low mileage and during the cold weather of course it gets a bit of a caning with the heater/air con, heated rear window, lights etc all on at once. Someone has said that some aspect of the climate control/heater drains the battery when the car is standing but don't know if this is true. Of course the alarm etc is on when parked so that is another possibility. Any ideas would be appreciated.
