    Knowing nothing of electronics, I would like to know if you were wire two AAA batteries thru a cheap diode how long would this last before depleting the batteries?
    Thanks

    depends which way around the diode is connected

    one way it would be an open cct and no current flowing
    the other way, a short cct and full current flowing and the diode is likely to die very quickly in a puff of smoke
