A dealer cannot legally void your warranty unless they prove that what you did, caused the issue. You’re protected by federal law.
Using a charger, like a Tesla Wall Connector, isn’t going to void your warranty.
I just read that, love how it says 85% then 80% a little further down lol.
I’ve also messed with the profile/timer before but didn’t have much luck, they don’t make it as easily as Tesla to set a limit.. makes me think they really don’t care as much, but just my opinion.
My Taycan is 4 years...
I just let mine charge to 100%. If they were really worried about the battery life, they would’ve built in warnings to not charge past 80-90% except for certain situations.
