Have these chargers actually restored unchargeable batteries to useable condition?
Yes. As long as the cells are not physically damaged or electrically shorted to other cells, our chargers can probably restore these batteries to useful service. Since the development of this technology, approximately 80% of the discarded or useless batteries we have tested have been able to be restored and put back to use. This “restoration process” is really nothing more than the charge process being done correctly. When this happens, the internal chemistry of the battery moves closer and closer toward it’s ideal state. Repeated charge and discharge cycles further improves this process. In some cases, discarded batteries that were regularly charged with Tesla Chargers gained in capacity above that of a new, identical battery. There is, of course, no way to know exactly how much restoration (or capacity increase) can be expected with any given battery because older batteries differ in their quality of manufacture, as well as the conditions they were subjected to during charging and lo
