China Battery Springs Factory: Reliable Battery Contact Suppliers for Consistent Power Delivery
Description
Q
What makes these battery spring contacts reliable?
Our battery spring contacts have been designed to adjust to varying battery lengths and provide low contact resistance and dependable connections.
Q
Which battery sizes do these springs work with?
Each of the four battery contact configurations is designed to work with the four most popular battery sizes: AA, AAA, C, and D.
Standard Battery Spring Material Options
The springs are offered in a choice of two materials: nickel coated music wire or silver coated beryllium copper. If our standard product designs do not meet your requirements, we can provide custom designs for battery springs, four slide part contacts or stampings.
Q
What other benefits does nickel coating provide?
Nickel will tend to wipe and aid in breaking down the oxide that can form on the battery metal contact surface. In addition, a nickel coating will provide general corrosion resistance and is an excellent conductor of electricity.
★
Silver Coated Beryllium Copper
Beryllium Copper is among the hardest, strongest and most wear-resistant of the copper alloys. The silver coating further enhances electrical and thermal conductivity.
Application
How does silver coated beryllium copper compare to other materials?
The electric conductivity is 65–70% that of copper; the strength and fatigue resistance are comparable to higher beryllium alloys. The light silver plating allows for easy soldering. Beryllium copper is corrosion resistant in various environments and is both non-magnetic and non-sparking.
Battery Spring Mounting Configuration Options
Battery Springs are available in a choice of four conical spring configurations:
Interior Mount – Designed for installation inside battery compartments
Exterior Mount – Positioned on the outside of battery housing
Adjustable Mount – Allows for flexibility in positioning and battery size accommodation
Double Mount – Provides dual contact points for enhanced connection reliability
Key Features & Solutions
Which battery spring mounting configuration should I choose for my application?
