Anyone know how to read the date code on a Halfords 005 battery?

Tbh I didn't know they had a date code but if they've got a bar code a smartphone bar code reader might give you a bit of info ?

I believe all car batteries have a date code, embossed/engraved onto either the top or one of the sides. Usually a series of numbers and letters (alphanumeric combinations, 6 or 7 characters) and some of the letters/numbers denote the date (month/year) the battery was made. I have one in my car which I'm trying to find out how old it is (came with the car) and I dont know how Halfords mark their batts.
