You can try to save them by basic cycling on them.
Heres what I do:
Charge at 5.0v discharge at 20 amps to 5.4 v
Then leveae them there for a day and put on the tray before chagring up agian. I put them on till them little light is almost dead on each cell. then chagre right after you have undone each cell on the tray.
Then repeat this for about 3 days or 4 days and then leave your packs at 5.4 if you race weekly on every other week. ANylonger put a little chage in each. So then when you are ready to chage all your packs will be at 5.4 v so you can just put um on the tray and chage
