NiCd batteries are built using nickel cadmium.
Soldering forms a permanent bond between two metal objects using another alloy (metal). When building battery packs with several cells, the process of soldering can enable you to connect several of units together with minimal electronic resistance between them. Learn solder you NiCd cells to unite their individual capacities and render a durable, high-capacity battery pack.
Instructions
1. Align the battery cells in series; the positive (nubbed) end of one battery cell will connect to the negative (flat) end of another. This will combine the energy of the entire line of cells into a single unti of energy storage.
2. Heat the solder iron, then touch the side of the battery you want to connect with the solder iron for a few seconds. Melt some solder onto the surface of the battery and mush it against another battery cell.
3. Hold the batteries in position while they cool down. Wrap the two with electrical tape to take some of the stress of the solder joint in case the cells are exposed to physical impact.
