It said to solder the positive lead to the back (which was easy), and the negative
to the front. I thought that was strange since the front surface area so
important, and when I tried it seemed to get quite charred, but I still got a
voltage reading. The main problem was that the solder wouldn't stay on the cell,
and poped of with the slightest pressure. If you have any further advice, I'd
appreciate it, but it probably just gonna take more practice.
Wondering Aimlessly,
