How to find out the maker of the battery?

My Y was manufactured in early 2020. I'm curious to know who the manufacturer of the battery is. How can one tell? Thanks.

Which battery do you mean? The 12V battery used for lights, fans and lower voltage equipment or the high voltage battery which is associated with the car’s range?

The Big One.

Tesla used Panasonic cells in the US and Signed on with LG to supply China later on in 2020. An early 2020 would be either LR or P and have the Panasonic cells assembled at giga Nevada.

Tesla made the battery with cells produced by Panasonic.
