Batteries?

    I am considering buying a Sony camcorder (probably the TVR 19) How long do
    the batteries last. By this I mean should I buy another battery for the
    camcorder or would one be OK and just keep it charged.

    Have just bought the TRV22 , and the first thing I did was to get a decent
    battery. The difference it made was surprising. Instead of seeing "dead
    battery in 15 minutes" etc., it now reads in the 100s of minutes most of the
    time - very reassuring.

    No. There's a whole range of different capacity batteries. All
    manufacturers ship their camcorders with the lowest capacity (i.e.
    cheapest) battery. Same with memory sticks/memory cards (for both
    camcorders and digital still cameras).

    Sorry, i was picking up on the statement :
    "the first thing I did was to get a decent battery"

    not decent = crap, YMMV

  5. What's the problem? What Tony said is 100% accurate in my experience. I
    remember well enough replacing the tiny supplied battery on my small DV
    cam, raising the camera to my eye and bashing my nose with an NP950.

    You appear to have underlined something Tx2 said. Why I don't know.

    They're not crap (IMHO), they're just low capacity. My camcorder lasts
    about an hour on the supplied battery, but with the biggest Sony
    battery it supposedly lasts 12 hours.

    I remember the first time I used a battery belt, put the camera down and
    walked off forgetting I was still attached !...
    The question was not "So Sony / make / crap batteries ?" but "So Sony / ship
    / their products with crap batteries ?". The point is, no one is doubting
    that Sony make and can supply decent batteries (which is the point Mr Morgan
    seems to be making) but one of the fact that they seem to / ship / their
    consumer camcorders with batteries that are more or less useless.

    The shipped battery is OK. But considerably higher capacity ones are
    available, at a price.

  9. The point is, no one is doubting
    A small battery isn't useless. It just isn't useful for as long as a
    bigger one :)

    That's why I said 'more or less' useless. :~P !!!!

    I thought I read that Sony LIion batteries do NOT suffer from "memory"
    charging habits( at least in the M series). That is to say, their capacity
    to hold a full charge as rated is not affected by recharges without waiting
    until the battery is completely drained. At least this is what Sony claims.
    Are you saying that you have experienced the opposite? My TRV38 came with
    the NP-FM30 which at full charge shows over 106 minutes (+/- 2 min). I have
    recently purchased the NP-FM91 which shows 746 minutes at full charge. I
    often will shoot a family home session for about 20-30 minutes and will then
    plug in the charger to top it off. You're saying that this will shorten the
    battery's ability to hold a full charge? Got any documentation to back that
    up?

    I really do suggest that you re-read what I said. You either don't
    understand what memory effect is, and/or you have difficulty in
    comprehending what "charge/discharge cycle" means. Here I'll help
    you....

    1. Charge half-empty battery = one charge/discharge cycle
    (nothing, you'll note, to do with memory effect).

    2. Charge empty battery = one charge/discharge cycle
    (nothing, you'll note, to do with memory effect).

    3. Use your battery for 10 minutes and charge = one
    charge/discharge cycle (nothing, you'll note, to do with
    memory effect).

    Irrespective of the mix of (1), (2) and (3), after about 100
    charge/discharge cycles your battery capacity *starts* going down. After
    about 120 charge/discharge cycles your battery will be down to about
    80% of that when new. And it gathers apace after that :-(
    It's inherent in Lion battery technology. In military applications, Lion
    batteries are replaced after 100 charge/discharge cycles.

    You might even note that the battery is specifically excluded from all
    camcorder warranties (and AFAIK all other devices that use Lion
    batteries).

    Anyone with a Sony Vaio laptop (which also uses Lion batteries) will
    understand and have experienced it. With Vaio's batteries each has a
    serial number burned into a chip and the battery management utility
    gives you a goodness factor for each battery based on the number of
    charge/discharge cycles (each charge/discharge cycle is written into the
    battery BTW)..

    Selective quotes taking it out of context shows everyone that you're the
    only twit here. Try reading you plonker - here, I'll help you if you
    find it so difficult:

    <QUOTE>
    The life of LIon batteries (how long it lasts until it won't hold its
    full charge) depends on the number of charge/discharge cycles.
    Constantly topping it up significantly reduces the amount of charge it
    can hold.
    </QUOTE>

    God, how do you get like you are - is there a lot of marrying of first
    cousins in your family?
    Civility - clearly a word you have difficulty with - just listen to
    yourself here!!

    You're one of these sad, sad people who, when they make an idiot of
    themselves, selectively quote out of context to try and restore some
    self-esteem (clearly you're deficient in that area).
    No. You just selectively quote out of context.
    Clearly the cop-out of the troll who gets found out...

    Show a little maturity and admit that you failed to read the sentence
    putting the phrase you picked up on in context.

    I wouldn't hold your breath on that hope there Ron. Tony has this way
    with people. If you prove him wrong, he'll resort to insults and try to
    steer the subject away from his error. Your best hope is that he'll
    killfile you. Shame really, sometimes he does actually know what he's
    talking about.

    - Dave.
