Excepting solar powered calculators, I don't know any models from any manufacturer, past or present, that could last as long on a set of batteries as the original Voyager series. 22+ years is an amazing lifespan for batteries sitting new in the package let alone for a set that powers a calculator in regular use AND keeps continuous memory intact 24/7. Like landing a man on the moon, I doubt we will ever see anything like that again in our lifetimes. |
