Production Date for PC

The Production Date application is an application used to know the date of production of the battery, by analyzing the letters and numbers on the battery.
For example, Hankook Royal batteries, made in Korea, contain a production date in the form of a normal date, such as 220127, which means the date 01-27-2022.
As for Hankook Royal batteries, which are manufactured in Spain, or Varta batteries, which are manufactured in Germany, when the following two letters HG are present, this means that the year of production is 2022 and the month of production is the month of 7
Year 2017 = C, Year 2018 = D
Year 2019 = E, Year 2020 = F
Year 2021 = G , Year 2022 = H
Year 2023 = I , Year 2024 = J
Year 2025 = K, Year 2026 = L
Year 2027 = M , Year 2028 = N
Month 1 = A, Month 2 = B
Month 3 = C, Month 4 = D
Month 5 = E, Month 6 = F
Month 7 = G, Month 8 = H
Month 9 = I, Month 10 = J
Month 11 = K, month 12 = L
As for the Hankook Royal batteries made in Bulgaria, the date of production is known through the first four symbols
The first symbol, which is a letter indicating the year of production,
The second and third symbol are two numbers to indicate the week number, as the number of weeks in a year is 53 weeks
The fourth symbol is a number that identifies any day of the week, and takes one of the values from 1 to 7
Year 2016 = G, Year 2017 = H
Year 2018 = I , Year 2019 = L
Year 2020 = M , Year 2021 = N
Year 2022 = R, Year 2023 = J
Year 2024 = K, Year 2025 = O
year 2026 = p
Currently, the letter G in Hankook Royal batteries made in Spain or Varta batteries made in Germany means the year 2021, and the letter G is reused after a period of time to mean the year 2047, and in some batteries such as Optima batteries made in Mexico, the date of the year of production is determined by a number where the number is 3 It indicates that the year of production is 2023, 2013, or 2003, and the date 2023 is taken because it is the current year, and the date 2013 can be taken, for example, if you think that the battery is not new
