Here is an article has some info on restoring LiPo cells. Batteries tend to exhibit increased internal resistance as voltages fall. The article empasizes that restoration doesn't mean the cells will be like new. They may have lost capacity and may have increased self discharge rates, but may also

I bought a pack or lihium ion of cells and they arived pretty much dead. like 0 or .25 each cell. I used 306b nicad setting to bring them up to 3.00, then swtiched to lipo to charge to 3.70 . someone told me that charging theses cells could be dangerous, because the dendrits could lead
