Date code for Phoenix batteries

Can anyone share the date code system used for Phoenix lead acid batteries? It is the 6 letters in the top line stamped into the to of the battery.

Here you go:

Thank you Nasir for the very quick and very useful response. It is a must watch video - I just got cheated by Modern Battery in G-6, Islamabad who sold me two year old Phoenix UGS batteries as freshly delivered stock (even showing me his recent purchase receipt for 40 pieces). When asked about date code, he lied and said they don’t know Phoenix date code system. Warranty card is also 4 page type (used only before 2018) and date stickers had been peeled off battery cartons. What a cheat! Fellow members avoid this shop in Islamabad!

Do complain to Phoenix batteries directly. If they are agreeable to it, they might swap your units with fresh stock.
