Taycan new battery 9J1.915.100.CX/BC

[Porsche Taycan]

Hi,
When replacing the battery with a new battery 9J1.915.100.CX/BC,
A full charge at a temperature of 20 degrees Celsius, reaches 380 km/h compared to 450 km/h in the old battery.
Has anyone encountered similar experience with a new battery? Any idea what's the reason?

Thank you.

You need to check the KW and not the kilometers. Kilometers will vary based on your driving past experience and means not that much. The KW will be precise however.

Thanks for the suggestion.
How do I check the KW?
