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.
