You see, by passing dead batteries off to these schmucks Waymo completely avoids any battery disposal problems. In fact, they pay for Waymo's waste.
They get to pretend that they are contributing to the green movement for a year or two before the batteries are so useless that they must be dumped or "recycled". But, that's not Waymo's problem.
It's a huge win, for Waymo.
Older EVs don't "die" like the cells in your flashlight, they lose charge capacity over time.
Specifically, once the battery goes down to below 80% of initial capacity, it's better for the company to swap them out for newer batteries.
However, 80% capacity is still a lot of energy storage, it's just that the energy density per weight (or volume) isn't as good for EVs. If your energy storage doesn't care so much about weight or size (concrete floor in an industrial building), then these things still store a *lot* of energy.
Also note: capacity degrades with "cycles", and grid storage does not cycle the batteries very much or very low. Taking the Australian Hornsdale grid storage installation for reference, they found that the grid battery would step in and smooth over what we would consider very short and very slight voltage drops, which meant that their peaker plants didn't have to spin up and down as frequently, which ultimately saved them $150 million (*) over the first two years, against an installation cost of $66 million (USD).
Since then there have been a number of other installations, so we have good data on what the expected outcome will be.
The term "schmucks" in your post is perhaps unwarranted...
