Better yet just throw them in the trash and get some new LiPos.
Sorry I just could not resist.
Actually we have about a dozen Nmh packs here at the Hill House, and they have been sitting in the drawer for about 8 months without being used, so I will more than likely have to go through the same cycling issues trying to get them back up to par when we want to use them again. Although from what I have read once you let them go to this point you will never get them back up to 100% no matter how hard you try. Good luck with that.
