  • Made to solder wires on.
I used these as a replacement for a Wasserstein solar panel that powers a blink camera. So far they are working well.

If you do not have a good soldering iron that can put high heat in a little spot quickly you will not be able to get the wires soldered to the batteries. ... show more
