My HP-15C revives......

[Thomas Okken]

So the secret of a set of batteries lasting extremely long in a Voyager is basically "don't use it"?

Still, impressive that those machines manage to keep their memory powered with such a tiny standby current, which is even less than the already tiny self-discharge current! And at the same time, running down a set of batteries within months, with heavy use including much running of programs, sounds like it is well within specifications, too. Nice to know!
