    I’m not maintaining the battery, what are you talking about?

      The battery is a “maintenance item” by manufacturers’ warranty standards. This means it has a predetermined lifespan and will need to be replaced during the expected lifespan of the vehicle and that replacement isn’t covered unless failure is caused by a manufacturing defect.

        Within my plans of owning the car for several years, it is not a problem. And even if I wanted to “ride it to the ground”, years and years of saving on fuel would pay out and the battery price would be just a fraction of that.
        The only point you write everywhere is basically “cars are depreciating”. Well, yeah, go tell the news to owners of turbo engines :)

          No, “cars are depreciating” is pretty far from the point I’ve been making.

          The point I’m trying to make is that manufacturers mislead car buyers about hybrids for the same reason they don’t want to build to EVs. The additional repair costs of ICE and hybrid makes car manufacturers like Toyota a lot of money. EVs eliminate those cost.

          The battery chemistry used in the car in the video is Nickel-Metal Hydride. Ni-MH batteries may have some defects, but what matters is that they discharge themselves. When the battery is not in use, it will slowly deplete its power. If the remaining battery time is long enough, the battery may be permanently damaged. A rough estimate of the depletion of NiMH batteries is that 20% of the battery power will be depleted within the first 24 hours after charging, and 10% will be depleted every 30 days thereafter. It is expected that the charge/discharge cycle of a standard Ni-MH battery is 2000 times

          Now consider the facts:

          • This battery will fully deplete when it is parked and this will lower the capacity
          • Because of how small it is, this battery will cycle multiple times per trip which will lower the capacity also
          • This battery will cycle 2000 times long before the warranty is up
          • When the battery no longer holds enough charge to fulfill it’s purpose before the warranty has even expired the cost of replacement will not be covered because it is considered normal for them to fail so soon. So the owner will have to pay.
          • you still have to pay to fix two drivetrains in a hybrid
