Some desktop chargers do have a discharge facility. Batteries can be restored, although not quite to their original specifications. There is a local company that provide a pickup and delivery service and they are able to test the battery and advise whether it is repairable or not. If the battery has failed completely, they are also able to repack the battery case with new cells. This usually works out cheaper than buying a new battery.
Fees do apply for testing, repacking or replacing the batteries.
