Will any diode work in the 4th battery location? I have a lot of DN4004 MIC. Unfortunately they are too short to span the distance so I am wondering what to use with it to get from + to -. Guess I could snip leads from another diode and solder them on or even put two diodes together in series....unless that's a bad idea.
Ha! I bought the same batteries yesterday! Half price! They will probably go in my trail cams instead of pins after reading this
