You don't. The firmware will shutdown the system forcefully at a point
before the deep draining happens.

What does envstat report for the battery with and without AC adapter?
Note that it can take a few seconds until it switches between both modi.

This is not that confusing. After all the hardware limit is the capacity
(which is not constant...). The charge state is about the capacity range
the battery is currently in. The difference in the naming is that the
static units are capacities and the dynamic units are charges.
