it may last at least last 7-10 days with a red led i think.you may increase its lasting by sealing the coin battery

Very good work, Argha. how many time the battery lasts?
argha halder (author)  rimar20002 years ago
i built it yesterday
and to test it i kept it on with the red led and i became surprised to see it was lighting so well .i have it beside me now turned on and it is still lighted .i think it would last at least 5-7 days.and you may recharge it by dipping the cardboard pieces again in the salt water or vinegar!
Wow! This is awesome, congratulations.
