I’m trying to learn how to electro etch copper using salt water and
an alkaline lantern battery. The first battery died after maybe 90
min of on and off again charge. The piece did etch some, with
striations, and not real deep. Took the battery back to exchange for
a another new battery tested to be fully charged when bought. I
hooked all up again in the same salt water I had used, now with
copper in it. Absolutely NO reaction ofbubbling. Tested the wires and
still showing juice, battery down to around 65% now.
How can a battery show a charge, power being drained, and yet no
reaction? The pieces are roughly 1 1/2" prices of copper.
I’m stumped and need some advice.
Thank you
Brenda
