    Ford Mondeo 2010: Battery keeps going flat

    Ford Ford Advice Ford Mondeo Ford Mondeo Advice Ford Mondeo 2010

    The battery in my 2010 Ford Mondeo Zetec goes flat at random. I replaced the original battery only to have the new one go flat. I have made sure there are no lights left on and turned off the stereo and air-conditioning. The NRMA checked the alternator and found it to be OK. Any ideas to fix this problem?

    If the alternator is charging ok, the problem must be a leak somewhere that causing the battery to drain. Make sure the lights in the boot and the footwells go out when you close the hatch or the doors. If they are working correctly it's really then best to see an auto electrician and have him trace the problem.
