About Custom Contact, Battery & Grounding Springs
Battery and grounding springs combine a mechanical contact requirement with an electrical one. Contact force must remain stable through tolerance and repeated assembly, while the material and plating must provide acceptable resistance and corrosion behavior. Geometry around the contact point often matters more than the overall part size.
Key Design Characteristics
- Contact normal force should be defined at the installed position, not only from free shape.
- Current path, contact area and allowable temperature rise influence material and plating.
- Repeated battery insertion or enclosure service can create wear at the contact surface.
- The spring should maintain useful deflection margin as cell length, stack height or enclosure tolerance changes.
What to Specify for a Custom Quote
- Installed geometry and available deflection
- Required contact force at the working position
- Current, voltage and acceptable contact resistance if known
- Mating material and contact-surface size
- Base material, plating, environment, cycle count and quantity
Manufacturing Review
For electrical contacts, plating and cleanliness can be as important as dimensional control. Functional checks may include force at height plus continuity or resistance requirements when specified by the customer.
Common Assembly Roles
- Battery terminals
- Chassis grounding contacts
- Sliding or compressive electrical contacts
Made to Order
How This Product Is Quoted
This category is reviewed from the drawing and working requirement rather than from a fixed public stock list.
Typical material direction
Phosphor bronze, beryllium copper, stainless steel, often plated (Ni/Au/Sn)
Why there is no fixed table
Contact force and travel are set by the mating connector or battery cell dimensions.
Next Design Decisions
Next Steps for Your Spring Design
Once the spring style is selected, confirm how it works in the assembly, which material suits the environment, how it will be manufactured and which dimensions and performance points should be controlled on the drawing.
Applications
Where this spring style fits
Review best-fit uses, assembly constraints and situations where another spring style may be a better choice.
View application guidance →Materials
Choose the material for the environment
Phosphor bronze, beryllium copper and stainless materials are common depending on conductivity, strength and corrosion needs. Plating such as nickel, tin, silver or gold is application-specific and should be chosen with the mating system.

Product Questions
Contact, Battery & Grounding Springs FAQ
Which matters more, contact force or conductivity?
Both. Too little force can make electrical contact unstable, while a highly conductive material with the wrong spring behavior may not maintain pressure through tolerance and vibration.
Can stainless steel be used for a battery contact?
It can in some low-current or grounding roles, but copper alloys are often preferred when conductivity is a primary requirement. The complete current and corrosion requirement should be reviewed.
