    Sorry if I just missed it but I cannot find a date decoder for this particular serial# config. It's a 2010 with 288,000 on the clock and I am trying to figure out if it is the original assembly before I crack it open. Every other serial # has either a letter at the beginning or multiple letters in the field.

    you really do need to crack it open to see if any cells have been swapped

    Date of manufacture is coded into serial numbers on each of the 28 modules. The outside cover doesn't offer that info.

    Check the car fax for any swaps. If none then it’s 12 or 13 years young.

    It is hard to test with any tools. Using Dr. PRius with a good ELF327 like Veepeak or Carista can tell the voltage fluctuation and internal resistance. At least you know it is still in a good range.
