Manufacturing date of New Hybrid battery

i was able to look at the numbers on the individual modules

 

Well, here's what I know as of this moment about the new coding. You have this sticker, plus you posted one earlier on another thread.

0F2PA-52031M1B8L0000067
0F2PA-52031M1C5C0000070

As with most, we can eliminate the 52031 since that is merely the last 5 digits of the part Toyota number.
With only these two full serial numbers, we can probably eliminate the 0F2PA from being involved in a date, but no 100% guarantee.
We can also eliminate the 0000067 or 0000070 since those are just the sequential order of manufacture.

That leaves us with M1B8L and M1C5C as potential digits corresponding to a date. Whether the M1 is part of it, I don't know. We probably need more serial numbers to help solve this puzzle, hopefully with a wide range of different numbers/letters in those positions. Then we can go through another process of elimination.

For a quick WAG (but still just a guess, and likely not correct)
If we say digit 3 of the above 5 digits=year and A=2020, B=2021, C=2022
and we say digit 4 = month = 1-9, then 3 letters not yet determined (could be ABC or XYZ?)
and we say digit 5 corresponds to day of month (but alphabet only covers 26, so 5 more 'symbols' needed)

We would have B=2021, 8=August, L=12... so M1B8L = August 12, 2021
and C=2022, 5=May, C=3 ....so M1C5C = May 3, 2022

Now look at the serial number of a module. That date code should be just like the older modules and should be within about 2 months or closer to the assembly date for the case.

 

I never tried to read the date from the external cover sticker
Because reading it from each individual module is still possible and they still use that code up to 2024 which is gonna be Z
Now 2025 they might need to switch to numbers or a totally different coding method ... Lets keep his up 6 months from now when we start seeing modules made in 2025

 

Heres an update, not sure what the date is:

 

15-th letter = production year
C - 2022
D - 2023
E - 2024
F - 2025

This is Toyota factory coding
0F2PA--76012B1D5P0000066

If you see a coding without dashes on a battery produced after 2022 it means you are looking at the replacement battery sold by Toyota dealer. This is what i've found out. I hope that's true.

This marking also includes a date. 0F2PA--76013M1E590000062
E - year 2024
5 - month 5
9 - day 9
The second quar code leads to the internal Toyota website
