Crystal Cell Research for Experimenter

Interesting how this cell lasted so long before the first maintenance cycle and then came back stronger...

Crystal Battery #353 - Built Nov 25 (white LED - dry build w/Borax)
Nov 26 - 1066 mV - day 1
Nov 27 - 1105 mV - day 2
Nov 28 - 1054 mV - day 3
Nov 29 - 1084 mV - day 4
Dec 1 - 1050 mV - day 6
Dec 13 - 972 mV - day 18
Dec 14 - 903 mV - day 19 - disconnected JTC to create a better connection, then forgot to reconnect it...
Dec 18 - 989 mV - day 23 - reconnected JTC
Dec 21 - 446 mV - day 26 - no light
- 961 w/no load, 0.8 mA on short, and climbing...
- 1.01 mA after a few minutes and climbing
- reached 1.09 mA after a few more minutes and began dropping
- 890 mV w/no load after short and climbing
- added 3 mL of water, quickly rised to 1600+ mV w/no load
- shorted, it started at 19 mA and quickly pegged the meter to over 200 mA
- set to the mV reading and it was showing over 1700 mV and climbing
- reconnected JT circuit, 1200+ mV under load, climbing
- after a few minutes, it is 1270 mV and still climbing under load
- JT amp draw is 5.9 mA... nice and bright!

That's very impressive.

That's very impressive. Fausto.

I just gave it another test since I know the water is settling. It's bouncing around 1080 mV and 5.3 mA under load.
To give you an idea of how this same circuit performs with standard batteries, I hooked it up to brand spanking new Energizer AA
- 1608 mV and 9.5 mA under load.
Then I hooked it up to a AA 1.2 V Ni-MH battery... it's about 6 months old, but has never been used... I don't think it is at full power...
- 1160 mV and 4.7 mA under load.
I think this is a great standard for testing the real power of these cells, which we could ask experimenters to do.
It gives a much truer baseline on the power of these cells than anything I've seen other experimenters do.

Publish that JT in detail so I can build one, please.

It's the one in the care package I sent you, minus the 3F cap...

Just pull the 3F cap, and you have it already built!
