R32 battery problem and long-term N-charge battery

Discussion in 'IBM Thinkpad' started by Nick, Aug 21, 2004.

    I hooked up an N-charge (Saphion technology) 8-hour battery for a
    couple of long-haul plane trips, and, later, when I went back to using
    the usual two-hour IBM lithium-ion installed battery, I found that it
    no longer worked -- at all. I tried a back up battery, it worked. But
    then, as a test, I hooked up the N-charge battery and ran it and when
    I was done, again, the IBM battery was dead and not revivable, if that
    is a word. Questions: Does the N-charge kill the IBM battery? IS this
    a matter of the N-charge being tooclose to the IBM battery or simply
    running the charge through it? Is it possible to bring the IBM
    batteries back to life? Or have I just learned an expensive lesson?

    If I understand what they're saying about li-ion batteries, you should never
    store them for any period of time at a completely discharged state. They
    have some onboard electronics which require constant power, and if they go
    *completely* dead and these electronics lose their memory, the battery will
    refuse to charge. It sounds to me like this may have happened to you.

    I've never heard of this "long charge" battery technology you mention, could
    you describe it? There must be some disadvantage to it or it seems like
    we'd all be using it right? Maybe it's oversized or something?

    thanks.

    I don't know, I didn't see the answer at batteryuniversity.com, but perhaps
    it's there.

    The long-charge battery is a flat thing, a battery, about the foot
    print of the laptop that allows 8-10 hours of use on battery. You plug
    it intothe machine with your smaller installed battery stil inside the
    laptop. To charge you plug the long life battery in and both batteroes
    are charged. The only problemis that the laptop now only runs on
    battery with the long-lie battery. The installed battery is dead. That
    answer the questions? I may have drained the installed batteries but
    never for very long. I sense this long life battery did something. I
    am just wondering what and if I canfix the short term batteries?

    Not quite, how does the long life battery make electrical connection to the
    thinkpad? Is it a cable that plugs into the same place as the power brick
    would? Or is it plugging into that odd connector on the bottom used by the
    port replicator?

    If it's plugging into the same place as the power brick, it would keep the
    built-in battery charged up, so I'm guessing it connects somewhere else.

    You could try the group comp.sys.laptops as there seems to be more activity,
    and perhaps more expertese on general topics such as batteries.
