just got a new battery for my air 2 and I see that the voltage is higher than the nominal voltage is this ok, or is this battery bad?

It's completely normal

Looks like a normal battery.  

Hi there. Thank you for bringing this query to us. After you fully charged the said battery, did you let the battery cool off for a few minutes before checking the voltage in the app? We will forward this screenshot of yours to our team for clarification. We will keep you posted. Thank you for your valued support.

We already coordinate this with our team and it shows that the battery is normal. Thank you for your valued support.
