How Do You Build A Nicad Battery Pack?
The battery packs that come with many electronic devices today are more expensive to replace than the device itself. Many times new battery packs are unavailable or difficult to find. If you can handle a small spot welder, you can make your own battery packs using the nickel cadmium battery cells that are often used in the original packs made by the manufacturers. Learn how to build battery packs and you can even make them for custom applications. Step 1 Determine the voltage you will need to power your application, and purchase the appropriate number of 1.2 volt rechargeable Ni Cad cells. For example, if you are building a battery pack for a 9.6 volt drill, you will need (9.6/1.2) = 8 cells. NiCad cells, as well as nearly all rechargeable cells, are 1.2 volts. Step 2 Arrange the cells to fit the shape of the battery pack you are planning. They can be stacked, staggered or placed in whatever arrangement works for the shape you need. Step 3 Spot weld nickel strips between each cell so t
