Here is the info I got regarding battery date codes.
There are actually 4 dates on each battery shipped to customers. The first is a ship date / Prop 65. This sticker is 2” square that states the month and year shipped in bold letters in upper right corner. The second is born on sticker. This sticker is a small white cycle with month and year batteries were activated. These stickers will be on the ends of the batteries. If these have been removed we also pin stamp into the back of the battery the manufacture date and brand the formation date code.
Manufacture code is a 7 digit code. The 2nd and 3rd digit is the day of the month. 4th digit is a letter for the month and 5th digit is the year. Example code, S03D3H2 this battery was assembled April 3, 2013.
Formation code is a 10 digit code. The 4th, 5th & 6th digit is the month. 7th and 8th is the day and 9th and 10th is the year battery was activated. Example code, SB2APR0413 this battery was activated April 4, 2013.

Vielleicht kann ja einer von euch es gut zum erläutern was da steht , 4.2013 kann doch garnicht sein ???20240522_181733[1].jpg
