Do I assume correctly, that if a powerpack goes down ,not all individual

How can someone check out which one to toss(into recyclebin) and which one
to reuse?

You can do this, but you this process may still leave you with a few
weak cells. Nevertheless, I do this frequently, and with excellent
results.

Just put the battery pack on the charger for a normal charging cycle,
then remove it, wait a few hours to let them stabilize, and measure
the voltage across each cell. Cells with 0-1V across them are
effectively dead. Replace them.

If you have a pack with a lot of cells in it, 90% of which are bad,
you should probably just replace all of them.
