Yeah, that's tiny. Can't read it at all. Please try again.
But, better if you can explain in text in case any other readers wish to
see your answer.

Sorry, misspoke, but this should help (let me know if it's not
reproducing well):

Still not clear, at least to me. Batteries - both lead and lithium -
seem to be able to hold a charge for months with little loss. In
practice for grid storage, I would think normally a week would be an
unusually long duration.

The limited ability of batteries to store energy for long periods of
time.

Why do you say "over long periods of time, not so much?" I would
agree it's hard to say whether we can attain enough used batteries
for grid scale - depends on how many EVs are produced and how fast
we ramp down mined-resource energy generation.

I agree with you on this...to a point.
For small scale and short time periods, batteries are great. For
grid scale over long periods of time... not so much.

I definitely would like to see incentives for installing
"depleted"
batteries as solar and wind backup.
We're at a point in time where we can promote both wind and solar
while
winding down coal and gas power generation. Clearly, before we can
retire all mined-resource power generation (primarily coal, gas,
nuclear), we need ways to store power for times when wind and
solar
don't generate enough.
Soon, we will begin to see a flood of depleted batteries from EVs.
With
incentives, the price offered for these used batteries would be
higher,
helping to lift the value of used EVs and increasing the demand
for new
EVs while at the same time helping to build our wind and solar
infrastructure.
In other words, right now, the need for utility level battery
storage is
low. But, gradually, as we retire coal & other plants, we can be
building utility battery storage and boosting EV production and
sales.
The sooner, the better, in my opinion.
