aluminum can and copper wire batterys

well .813 was the highest voltage read so I think you have me beat on the lemon juice

Well, I am trying now longtime tests
on a graphitepaper-alufoil test cell and so far it
looks quite nice.
The starting voltage without a charge is about 1.45 Volts.
After the electrolyte is a bit degraded, the cell
is down to about 0.9 Volts and stays there for a long time,
if you don´t draw much current from it.
You can also reacharge it several times and it will
behave like a combination of a supercapacitor and
normal galvanic cell.
After the charge it can go up to around 1.9 to 2 Volts
and then slowly goes down to around 1.3 Volts, if you
don´t discharge it.

I will tell more soon,
when I have done a stacked version with more cells
in series with much
more voltage.

Regards, Stefan.

i am leting mine set for 24 hours and see what happen then and then iam going to see how long it stay up or if it goes down fast yours mine go up in 24 hours

Stefan.

whats you geting on it sound like you might have somethere


thank for the info you two

Oh crap I already took my cell apart lol dumped all the electrolyte ...

I could try rochell salt and water...

Oddly the salt turned the gel into the consitancy of water maybe this is to be expected but i'm going to let the rochell salt dry out and harden for kicks and see what happens with it...

Greetings,

I created a Penny Pill Jar Battery (with Bolt).
1 Jar gives an approximate voltage of .650 Volts.

Two of of them in series run a JT just fine !

Will be interesting to see how long it will last.
The Picture Below should explain.
