I can’t afford apple to replace my battery for my phone and I don’t think they even have the battery for it anymore. So a 3rd party solution would be better and cheaper than apple. But if you’re giving to “Rando McRanderson” to reinstall the battery. You risk getting your phone damaged in general. I would recommend taking it to a professional repair shop or at least a reputable repair shop for this type of repair. The risk of damage is minimal and if something goes wrong with the phone after the repair was made and not there before, you can tell them about the problem and see if they did it. In OP’s case, he has to take it to a phone guru because I suspect his board is damaged and apple won’t do anything about it.
