The production date of the battery is not displayed in the Omni or the Omni App. However, it can often be determined from the serial number, which is located as a sticker on the top side of the battery beneath the battery base.<\/p>\n\n\n\n

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. \u201aA\u2018 for 2020, \u201aB\u2018 for 2021, \u201aC\u2018 for 2022, \u201aY\u2018 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.<\/p>\n\n\n\n

Stromer coding is not standardized. Here is an example:<\/p>\n\n\n

Specifically with the ST1306AC... serial numbers, the manufacturing date cannot be easily deciphered.<\/p>\n\n\n\n
