Crystal Batteries #'s 356-357 - created Dec. 1, 2014 (7 days old today)
356 - original reading under load 870 mV - white LED
- current reading 638 mV = 232 mV total loss
- average loss 33 mV per day
357 - original reading under load 930 mV - green LED
- current reading 675 mV = 255 mV total loss
- average loss 36 mV per day
These were the same build and same JT, but different color LED's, which although are rated the same, are slightly different.
There is still enough light for a nightlight, but when they get down to around 600 mV, I will add some water and reseal.

Thought you graph geeks would like to see a graph! lol

This turned out to be a weak cell. I think it is the borax crystal on the mag strip. I will recycle #'s 344-345 and use a hydrogen
peroxide solution to clean the mag strips from them to see if this makes a difference. I did learn that standard 3%  hydrogen
peroxide does a great job cleaning off copper and magnesium. There was approx. 44" of mag strip in this build. I tuned a new,
really easy to build JT circuit for this cell and it is running really well. No more resistors or caps! Video coming soon! 42+ volts
from this weak cell with the new JT circuit! Stay tuned!

PS - I was worried I was going to fry the 3904 transistor, which is rated at 40 volts, but I left it hooked up for an hour before I
connected it to the crystal cell and it seems to be fine after the final build! Note that I gave this cell a 30-second zap too...

So.. using my oscilloscope connected to the new simplified JT circuit between the emitter and collector, I was seeing 20+ volt spikes and
was happy with that, but when I pulled it from the bread board and soldered it together, I was getting over 40 volt spikes. Note that my
new Crystal Battery #361 is very weak and it still does excellent with this tuned JT circuit. I spend the last 3 days on this, so the main
benefit is that I have now ditched the resistor and capacitor so that this JT just has 2 inductors and a transistor. IT's an easy build and
doesn't even need a circuit board to solder it together and fit it on my little shelves. When I shelved it, #361 was showing only 577 mV
under load and it is still my brightest nightlight at the moment. One note... this JT config draws more mA... over 7 when I checked prior
to mounting on the wall....

PS - I am still not sure if zapping the cell really helps. I think just putting it under load right away will polarize the cells and zapping them
may be an unnecessary step. I'll push forward over the next few months to determine that...

@ Fausto I have no doubt your cells are ligit
I don't have equipment for 60v I can do 30v though
I'm going to make new cells and although a 100 ohm resister load sounds very boring to me I'll do it because you asked and I'll chart it
My intuition tells me that zapping speeds the process. In my own cells I've seen where copper turns the Rose color, but it took months For it to happen.. Time will tell. I am enjoying myself in all this
