    Just buy brand new cells from NKON with tab pre-soldered, they will cost you the same.

    Finally my Simplo battery pack from Dell which was a spare that I ordered 4-5 years back is now permanently damaged, that's what the machine showed today. Suddenly the battery was 0% and I tried to make it express charge and normal charge, it wouldn't. So I tried to remove the connector and powered the machine on, that message came. It has been a good run and a very reliable hardware. Now I will probably have to soon try to learn more on this and perform this repair.

    Did you even try to reset the battery cycle count when the new cells were installed?

    Did your cell change work?
    Often hear laptop battery controller be a problem, if you change cells and new cells gets reported as faulty.
    Did you something special like keep cells connected parallel, to out play that?
