Pro controller has killed 2 batteries. How do I check the charger?
I have a switch pro controller that had a battery die in it after many years (the battery puffed up). I bought a third party replacement since that was all that was available in my country, but this battery has also died after the first time recharging it. I think there's a problem with my pro controller's charging circuit. Any videos or guides on how to diagnose the board?
