Battery age

How might I find out when battery BE2231G069 was made?

July / August 2022.

Rubikcube How did you work that out, I'd be interested in knowing the manufacture date of my 2 9.5kW batteries

Graham_Harrison iirc the serial number includes it, so 2231 is year and week number, so week 31 of 2022
