Battery Contact Design

A battery contact & spring typically performs two roles - to help provide pressure in order to hold batteries in place, as well as to conduct electrical current to the desired circuit. The force exerted by the spring on the battery often affects the electrical conductivity, especially where surface oxidation on the battery contacts may be present. Corrosion and oxidation, as well as the battery spring’s suitability for specific soldering processes, should be considered during design.

Battery Spring & Contact Materials

Material Conductivity

Conductivity is a critical factor in the performance of battery springs and contacts, directly affecting the efficiency, power output, and life span of the battery. Selecting the right material for your design is essential, as different metals and finishes offer varying levels of conductivity, durability, and corrosion resistance.

Why Material Conductivity Matters

The choice of material directly influences the efficiency of power transfer and the stability of the battery connection. By carefully selecting the material, you can achieve an optimal balance between conductivity, durability, and cost, ensuring that your battery springs and contacts meet the specific demands of your application. Here’s a quick breakdown of a few common materials we offer, but make sure to contact us for a more in depth conversation of optimal materials for your design.
