2018 s75d - More range up to 300 miles

[rasa.sri00]

I have purchased pre-owned tesla sep 2018 s75d model from non-tesla showroom.
24K miles
when I charge 90% , I see 259-260 miles and for 100% and I see the range 290-299 miles. I am not sure why I see more miles on my tesla model s 75D
I don't know my previous car owner has upgraded the battery? I am not sure it is even possible to upgrade battery on 75D?
Could it be a bug?

I don't like to reach out to tesla support as they might reduce the range.

Switch the setting from "ideal" to "rated" miles.

Also the battery label is visible from behind the right front tire.
