Why don’t refurbished Prius battery sellers show cell specs?

Would you trust a seller more if they listed both warranty and cell health specs?

  1. Price + warranty is enough

    Most sellers of refurbished Prius batteries advertise only by warranty length — 6, 12, 24, even 48 months.

    But they rarely (almost never) provide actual cell specs, such as:

    • Capacity (Ah)

    • Internal resistance (mΩ)

    • Voltage balance (mV)
    It seems warranty length basically reflects these hidden numbers: weaker cells = shorter warranty, stronger cells = longer warranty.

    Warranty is only a useful number for a company large enough that you expect it to be around so that it can honor that contract.

    it's probably the same batteries, the extra money you pay for a longer warranty is insurance
