vision battery production date codes?

[rgormley]

I am looking at buying some AGM batteries and was trying figure out how old they are from the stamped numbers and letters on top
can anyone tell me the production dates from this?

model: Vision HF12-560W-X
stamped on top BJ26HA7GK34

Cheers,
Richard

anyone?
UPDATE:
for what iy`s worth i sent an email to Vision USA, and they came back saying "Oct 2022"
i presume the B:2020 and the J is oct
follows the standard i guess,
i have asked them to follow up on the remainder of the letters "26HA7GK34"

I can't see how the "B" equates to 2020 when they have said 2022. In any case if B=2020 then A must be 2019 ? So a battery made after say 2006 would be ????. A speck sheet I have shows the data for the HF series being released in 2004, so the code would have to be able to interpret
that. I just can't see hoe B being either 2022 or 2020 can do that !
