2002 2.0 TS2 - possible battery problem? -
My mazda6 keeps getting what appears to be a flat battery. Its happened three times now and its always after my wife has done a very short journey (<3miles) and had the headlights on and air con to demist the windows. Its done this even though the previous journey was fairly long so i would have thought the battery would be fairly well charged. When i put the battery on charge, the charger shows the battery to be fully charged after just 10mins.
Basically is my battery just knackered? Its 5 years old.

Five years is a reasonable age for a battery. They are constructed with a lot of thin plates which enables them to produce enough current to start the engine even when they are on their last legs - providing it starts easily. The power for the electrics is provided by the alternator once the engine is running, so the type of journey shouldn't affect the cars ability to start. It could be that you have an alternator problem, or just that the belt is slipping. Connect a voltmeter across the battery with the engine running - it should read 14 volts, much less and you have a charging problem.
