===Disabling third-party batteries===

A common issue where third-party batteries that were working perfectly fine without being ~~allowlisted~~ suddenly got disabled and, as a result, no longer charge nor function.{{CitationNeeded}} There are no error messages, and the only way to know is to install the Vantage software to see the non-genuine battery warning. {{CitationNeeded}} This is a critical issue, as perfectly working hardware that is slightly outdated by a couple of years is basically turned into e-waste, and original parts are getting harder to come by with every passing day.{{CitationNeeded}} ~~Though it~~ is possible to salvage a heavily used part online, tear it down for a board donor and ~~resolder~~ it with new battery cells. Initially it shows low health, but with more cycles it seems to be able to calibrate health data. ~~<gallery>~~
