Lee’s Battery Springs are conical springs that are perfect for prototype and small run production, as well as larger runs. These economical and reliable battery contacts, ideal for molded cases with self-contained battery compartments. These battery contacts have been designed to adjust to varying battery lengths and provide low contact resistance and dependable connections. Each of the four nickel coated metal battery contact configurations are designed to work with the four most popular battery sizes: AA, AAA, C and D. Custom designs are available as well.
Lee Spring now offers our unique line of Battery Springs in a choice of materials.
Silver-coated Beryllium Copper
- Beryllium copper is among the hardest, strongest, and most wear-resistant of copper alloys.
- Silver coating further enhances electrical and thermal conductivity.
- The electric conductivity is 65 to 70% that of copper, and the strength and fatigue resistance are comparable with higher beryllium alloys.
- The lightly silver-plating allows for easy soldering. Beryllium copper is corrosion resistant in various environments, and is both nonmagnetic and non-sparking.
Material: Nickel Coated Music Wire
- Since most alkaline batteries have nickel coated containers, a nickel coated contact is suitable.
- The use of similar materialsremoves the possibility of galvanic corrosion and aids in wear resistance.
- Nickel will also tend to wipe and aid in breaking down the oxide that can form on the battery contact surface.
- In addition, a nickel coating will provide general corrosion resistance andis a good conductor of electricity.
Lee's Battery Springs are available in a choice of four conical spring configurations in either material:
