They're lithium ion. It's probably got more to do with good hardware design.

I find it hard to believe that they kept 100% charge for years even if perfectly designed. 🤷‍♂️

me too honestly. They seemigly never did it again, and nothing else has ever compared in that specific trait, so whoever actually made the batteries must have been laid off in favour of planned obsolescence. Some time ago I saw some article or post about why batteries degrade and potential ways to prevent it, but it seems to have disappeared from this plane of existence entirely.
