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.
