Walt?s battery voltage over time

[hartiberlin]

Hi All, here are 3 Text files from Walt with his battery voltage on a load resistor.
As I only have installed the Excel viewer, but don?t want to installe Excel itsself,
maybe someone else can just quickly import these files anddo a graphic
from Voltage over time ?

There you could see very nice, that the voltage also increases again after some time.

Many thanks.
Please postthe graphic in GIF or JPEG format. Many thanks. Regards, Stefan.

hi all,
today we got a verry good x-ray influence, the voltage of my testcell was during the time from 10.00am to 4.00pm increased from 0.673 V to 0.701V under load with a 47 ohm resistor. the total running time continiously with the load is now 90 hours.
greetings

Walt, sounds good.
I realized today, that it is really needed to really enclose the cells, as you also already said Walt,
so they can?t dry out.
Some other cells, that has dried out still give very good voltage of
around 0.9 Volts open circuit, but if you put a 50 ohm load resistor on to them,
they go down to about 0.05 Volts, okay, these are the older cells,
the nonenclosed 1st AGC cells go down from 0.8 Volts to 0.4Volts and then
in about 10 minutes go down to 0.15 Volts.
But these are all dried out.
The next cells I will build will be enclosed in total plastic foil, so they can not dry out.
It seems it is very important to get the right wetness at the start and then
keep it at this wetness, to wet is also not good, too dry is also bad,
so this must be right  tuned. Not so easy...
