    Hi,

    I have a need for a trickle charger for a car battery - needs to be able
    to be left on permanently, in a usually unoccupied building, but once
    every week or two, the battery will get some reasonably heavy use -
    driving motors to open sliding doors, moving an 8' dish up and down, etc.

    Is this a feasible thing to do - I'm not bothered about replacing the
    battery every year or so - more concerned about gassing problems while
    the building is shut up, with possible risks when people next go in
    there. If so, could anybody suggest a circuit anywhere - I've tried the
    usual google search, but get flooded with replies, none of which seem to
    answer my needs directly.

    Thanks

    Gary

    The battery manufacturer should be able to tell you the recommended
    float charge voltage for the battery. Assuming you don't have extreme
    temperature variations, I'd put a 13.6V current limited
    supply on it and "ship it".
