The barcode is a series of numbers and letters written in plain text directly below. This in turn contains the coding for the production date. It often contains a letter (e.g. ‚A‘ for 2020, ‚B‘ for 2021, ‚C‘ for 2022, ‚Y‘ for year, etc.) or a number, followed by the year and month of manufacture, sometimes separated by a W (week) and followed by the number of the week in the year in which the battery was produced.
Stromer coding is not standardized. Here is an example:
Specifically with the ST1306AC... serial numbers, the manufacturing date cannot be easily deciphered.
