The team used advanced spectroscopy techniques to confirm the prototype’s charging behaviour, which showed it retained stored energy for six orders of magnitude longer than it took to charge.
They do say “6 orders of magnitude”. So a million times. No idea what the absolute numbers they’re dealing with here are, but a million seconds is 11.6 days.
more a capacitor than a battery.
