1) You only need to fully discharge nicad batteries before recharging -- lithium batteries don't require that. 2) Batteries have a finite number of full charge/discharge cycles they can handle, typically on the order of hundreds. You've now charged/discharged your lithium ion batteries a lot, so you've lowered the amount of charge the batteries can take. 3) FYI, you have to generally expect that, with time, lithium ion batteries will manage less charge almost regardless of what you do to them. Replacing the batteries every couple of years is pretty much a requirement. 4) It is possible to replace the lithium ion cells in battery packs on your own (they typically look like "normal" cylindrical batteries) without having to buy a whole new battery pack. Depending on how cheaply you can get the replacement cells and how good you are with tools, this might or might not save you a bit of money. Google around for information on how to do it.
