New pic from Saltwater cell in tic tac box

[hartiberlin]

Hi all,
this is a new picture from my latest cell in a tictac box.
There are 2 alloy and 3 graphite plates in it and Walt?s
powerpowder also in it.
When I connect it to a 50 Ohm load resistor this cell
goes down to 0.7 Volts as shown in the pic.
Now after 15 minutes the voltage is down to
0.62 Volts.
Normally it stays a few hours over 0.5 Volts with this
50 Ohm load and only goes after about 12 Hours to around
4.8 Volts and after 2 or 3 days to 0.42 Volts.
So, if you give it a rest each day for a few hours, this
can refresh itself and then begin again with 0.7 Volts.

Regards, Stefan.

Now after 17 hours of permanent 50 Ohm load the cell voltage
at the 50 ohm load is down to 0.5 Volts !
this is still pretty good !
These cells have a very long lifetime, if you let them rest now
for a few hours and then use them again for 12 to 20 hours !

Regards, Stefan.

Here are 3 more pics of the TicTac box cell.
The graphite plates have sucked up the saltwater and
some corrosion can be seen as the crococable
also gets salty.
This can be avoided with a different design.
The voltage is still at this time ( after around 12 hours
when the pics were taken) at around 0.54 Volts
at the 50 Ohm load.
