H20ZW 20 = day of month Z = month (December) W = year (2019) If a W was on a module, it would signify 2 years later (2021) for the manufacture date. So it looks like your car has an OEM replacement with a manufacture date of 12/20/2019 If you were to peak at a module, the letter code should show a manufacture date within about 2 months of the exterior date. The letter code should be a U for 2019.
Thank you so much @TMR-JWAP I was a little confused on which sticker I had and now I get it. This is great news for me too since I was not sure if it was an original!
251Y 25 = day of month 1 = month (January) Y = year (2023) This module has a manufacture date of 25 Jan 2023, so pretty new.
Sure. This image and the decoding information were originally posted by (IIRC) TMR-JWAP. (My apologies to the OP if I'm not recalling correctly.) I marked it up and notated it for my own quick reference. I hope that helps. A quick question for anyone who knows, I just noticed J at pos 3 and H at pos 5. Is pos 3 the manufacturer code and pos 5 the model code? Note also, that there is a newer again serial number format for which I have not seen any decoding information, so if anyone has worked that out, it would be good to add to this post.
Help needed: My serial number is 0f2pa4247031m1e1j0000031 When was this manufactured ? Hopefully not anywhere close to 2007
The Toyota label has 240118 printed on it. That may be 24 Jan 2018 if in DDMMYY format. It could equally be 18 Jan 2024 if in YYMMDD format. Neither date is close to 2007. When did you buy the battery?
