    Hi , having a 12-Cell Lithium Ion Battery that goes on a NEC laptop.

    The battery doesn't keep the charge for a long time. Are they repairable ?

    Probably not. Particularly if it is over two years old. Here is an article.
    You might try fooling around with the charge discharge cycle and let it go a
    little deeper (but not to 100% discharge) and see if that helps.
