    Hi friends,
    My hybrid battery is dead
    (along the years I've replaced dome cells and balanced them by own).

    I've found someone that cells complete pack.
    I'm trying to understand if there is a way to know the manufacture date by the sheetmetal serial.
    At least to get some idea before validating on the cell itself.
    Any help will be appreciated.

    Attaching the serial image.

    Sells a complete pack of what refutbed modules . That won't have anything to do with the QR code or the sticker on that battery because what's inside case is no longer original .! Now if he saying their new then that code on label should have some mfg info I'd think. Original batteries to the cars didn't have QR or this info stamps on them . Later units did . And I thought mfgr date is contained in that info tag .

    Thanks Tom!
    So do you belive that since this pack has qr code on it, it might indeed be newer than original?
    (off corse I'll have to verify the date on cells)

    Trying to avoid unnecessary drive in advance (seller mentioned tjis is ~3 years pack, as he knows. He is car dealer)

    The serial numbers on each module need to be in numerical order with same date of manufacture if you want to be certain your pack will last as long as possible:

    Oh you want to open up the pack and inspect module by module oh holy Christ no I ain't going through all that not at all.. my cars have new batteries because I put them in there I don't need to check and wheni buy a car I know the battery is going to be enrouye out duh obviously why do you think they're getting rid of the car. Or all the brake codes are up that's aboutit for the cars other than reg ice and trans .

    Yea... But how are you going to know if you won the Prius Lottery? As in sometimes you can buy a used Prius and pull the pack and go through module numbers a realize they're in sequential order (meaning brand new) and then realize date of manufacture is not as old as the car but that car got a brand new battery just a few years before you bought it. That's a winning lottery moment right there!
