    Battery drain

    New Bosch battery fitted a few months ago. Went to start car last Monday morning after car sitting since Saturday night and it was completely flat. Got it jumped and it was ok up until this morning again, it's not completely flat but hasn't enough power to start the car. I drove the car last night with no problems. Any ideas

    As the battery was drained you should get it charged fully by an external battery charger - driving the car (using the alternator) will not get the battery back to a full state of charge and will lead to the battery becoming ineffective prematurely.

    It received a full charge with an external battery charger. Battery has lasted about a week and a half and is now flat again

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Go to a service and check you Alternator. Maybe is not charging to the correct voltage.
    I heard of people complaining about this, charging only 11.2 instead of 12.4 as example.

    How old is the battery? There's a chance that, if it's not parasitic battery drain, the battery might be at the end of it's service life.
