    Laptop Li-ion battery repair isn't really an option because reseting the
    contoller inside the battery just isn't possible. Given the price of a
    new battery is prohibitive and, if it's an older laptop that one doesn't
    want to replace, availability of batteries, especially given their 3-5 year
    shelf life, is also a problem even if one were prepared to pay the asking
    price.

    Other than running with a dead battery or removing the battery, are there
    any other options for restoring some sort of operation remote from the
    mains?

    Many thanks.

    External gel lead/acid battery, with a small invertor maybe ?

  3. In most countries there are local businesses that specialize in laptop
    battery replacement.

    Most laptop battery controller chips can be reset. Some companies publish
    the method, some do not (STFW).

    The problem with Lithium Ion batteries is that they have a limted number
    of recharges. It's around 300. Once you go over that limit, they become
    useless very quickly. It seems odd because you have a full charge one day
    and the next a full charge lasts about 10 minutes and shortly thereafter
    a full charge won't even turn the unit on. :-(

    Apple had this problem with early iPods. I have several Motorola phones
    with dead batteries soldered in. I also have several Macintosh laptops
    which are perfectly useable (and run the current version of MacOS)
    that have dead batteries and a replacement battery would cost more
    than a newer used laptop with a good battery.

    Someday, I'll open them up find the correct cells and rebuild them.
    Apple even provided a program to reset the controller chip. :)
