    Bad attempt at humor, sorry (it's Star Wars btw).

    I think you're probably right. If it was an older car, I guess one could
    try to use a multimeter and measure the flow of current over the
    different curcuits in the fuse box - and search on from there, but with
    a 2007 CRV it should not be the owners problem, but the dealership's. A
    current that empties a car battery in 2 days should be possible to
    measure and locate.

    How can you be so definitive? It could be an old battery, it could be
    the alternator, it could be regulator(imbedded in alternator), it could
    be simple loose connection or leakagy or something is drawing current.
    How old is the battery?

    and the response(big lie) from the Honda service person was totally
    unacceptable and should be reported to the proper Honda representative.

    Did you read the subject line? It's a *2007* vehicle. How old do you
    think the battery is?

    He said it's been into the dealer's service department already (twice). A
    loose connection would have been found.

    That leaves what? That's right. The alternator.

    Spoke to the service manager today re: my wife's '07 Odyssey that I posted
    about elsewhere in this thread...

    He said he has seen a bad batch of relays. They stick in the closed
    position leaving power on to various systems in the car and that might be
    the cause that is draining the battery so fast.

    He is picking the car up from my wife's office on Friday to check/replace
    the relays in question as well as put a new battery in A) just in case it is
    a faulty battery and B) it could eventually die a premature death from
    having been run flat a few times already.

    what is it with Honda and bad relays? (the infamous "main relay"!!)

    I wonder what manufacturer made that batch in your 07?

    Age aside, a battery can have a internal electrode short, one cell dead,
    broken connection inside, etc. Most weakness amongst auto mechanics is a
    lack of good knowledge in electronics/electricity. Old grease monkeys
    just don't cut it nowadays. Still you can't blame alternator outright.
    As a retired EE, I always managed to solve electrical problems on my
    fleet of family cars/truck. So far I never ran into a mechanic who
    impressed me as far as electrical problem is concerned.

    Why dealership? Anyone can do this test with a small 12V bulb if neter
    is nat handy.

    <sigh> I guess you haven't read his original post, where he said the
    dealer had already replaced the battery....

    Do you still think it's the battery?

    As I've been saying all along, it's the alternator. Thanks for playing.

    You are not reading my post well either. I covered most of everything.
    Usually battery is the first thing they replace without good reason.
    When I investigated swapped out batteries, almost 80% was in good shape.
    My brother(chemistry major) once worked in Exide battery plant. We
    talked a lot about batteries. I live in very cold climate. Keeping a car
    in good running order is a matter of life and dead in winter time.

    I am reading your posts just fine. You are lacking in comprehension.
    OK, this may be true. However................................. since
    they have *already* replaced the battery, and the problem is still there,
    it's *NOT* the battery causing the problem!!!!!!! Why can't you
    understand this???
    Whatever. Completely irrelevant to the discussion.

    Just an update. It seems they have found a phantom load that is discharging
    the battery but they have yet to figure out exactly what it is. Since all
    items are Honda installed and supplied they can't blame it on anything else.
    The new battery (3 weeks old) is fine and they report the alternator is fine
    as well.

    Ask them if they checked for stuck relays.
