I have a problem with a battery drained of power on my Peugeot 306, If I leave the car 2 to 3 days then start the engine it labours to fire up but is ok when it does start. But if I leave the car for a week or more I have a dead battery, I know it's not the battery because it's brand new and nothing is left on lights,radio etc. Anyone have any clues what the problem might be or what I should test,it's been doing this for the last 6 months.
