http://exxos.www.idnet.com/IMPULSE/battery/battery.htm   same article on making the chemalloy battery ,but some guy says the 130mAs must have been in error and maybe it should read .130mAs.He does his own experiment with a steel bolt and a carbon rod.He reports on his low power results at the bottom of the page.I don't have a chemalloy rod handy or I could do a quick test.He did test the same electrolyte.

...Instrumentation error in above video....no meter reads accurate on amps scale without
an external load resistor being present. All meters are designed to measure current flow
*through user supplied load resistor*. Also a specific load resistance will not show the
maximum capability of a power supply, you must scan a range of resistances then calculate
the maximum of [volts times amps] at a number of resistance setpoints then find the
maximum value. So maximum *power* reading from any power supply or amplifier is an
optimization procedure unless you have a very specialised instrument or admit to the
device having a constant known "internal output impedance".

People making this error are newbies and should not be trusted.

I made 6 more crystal cells today using dandelion leaf and the six magnesium strips that I used borax to protect.They are a black color(magnesium borate?)Can't be an oxide here. So now Im waiting for them to dry.triffid

Thanks  :S:MarkSCoffman,A bunch of us need to go to class on how to read our meters.I would go too.I was really wanting to use chemalloy as an electrode.But now I am not so sure.I do think my meter acts as a load when I read for amps.I wait until it drops(amps) as low as they are going to go after a minute or two.Then switch back to volts only to find out that they have dropped and watch them climb back up.So I try to read volts first,then amps with my meter.triffid

The latest meter I have been using is an analog DC watt meter that goes up to 2 milliwats. It is an old DB meter but seems to read more 'true' on the actual 'power' that I am getting with my DMM (which I always mistakenly call a VOM...) set on 'volts' or using an analog micro/milliammeter gauge (without the resistor).
Today I hooked up a couple older analog meters and they seemed to work well. The resistors are in the four position multi-switch that came with them (I got them a couple months ago) so I need to build a box and get some connectors to turn it into more of a test rig. Also played around with the FG and my scope... Busy Mom's day...
No new cells this weekend, maybe this week sometime.

Happy experimenting,
