I have a 2020 992 4S. Dealer wants over $1,000 for a new battery compared to most suppliers under $200. Is there something unique about the Porsche battery?

 

I also have the same 2020 911 4S and the Li battery failed two months ago. Porsche Sacramento CA. changed Li battery out, battery $430, labor $225. They said there a 4-5 year life expectancy is normal. (A PCA discount helped)
I had GREAT service with Porsche Carlsbad for several years, head South
