    LOL, the "key" is that Toyota gets to define what "battery life" means.

    They never, at least in the U.S., allow full use of battery power,
    instead they turn on the gasoline engine ridiculously early. On non-U.S.
    Priuses there is an option to run down the batteries further, increasing
    fuel economy. On the plug-in conversions, the replacement battery pack
    gets to run down to a reasonable level before the gasoline engine kicks in.

    When does a battery no longer qualify as "good?" When the batteries
    _never_ take over, or when the battery is retaining only 80% of the 55%?
    Do they then reprogram the computer to allow the battery to run down
    below 45%?

    Essentially Toyota put in a far larger battery than necessary,
    considering that they never allow it do discharge to more than about 1/2
    of its capacity.

    It's similar to "normal oil burning." Even though a modern gasoline
    powered vehicle should burn very, very little oil, the auto
    manufacturers have defined themselves a threshold of "normal" that
    allows them to deny warranty service on vehicles that burn far more oil
    than they should. Complain about it, and they'll refer you to the
    owner's manual which has their definition of "normal."
