I attacked the "bad" Sony battery pack with a Dremel-powered cutoff

I have no intention of trying to restore or replace these cells,
especially as they aren't interconnected in the way you'd expect.

The question remains... As nicads and NiMH cells are charged by constant
current (theoretically, anyway), what would cause the total post-charge
voltage to hit nearly eight volts?

I'm no expert, but why not ask you question he

I've used this site for years when I want to figure out something
battery related...
