Frequently Asked Questions
Q: Are these nickel sheets compatible with 18650 lithium battery spot welding machines?
A: Yes, these polygonal nickel-plated connection sheets are specifically designed for use with 18650 lithium battery packs and standard spot welding machines. Their clean, degreased surface and precise dimensions ensure reliable spot weld adhesion with minimal setup time.
Q: What thickness are these battery nickel connection sheets?
A: Each nickel sheet is approximately 0.18 mm thick, making them ideal for standard 18650 and other lithium battery pack assembly applications requiring thin, flexible, high-conductivity connectors.
Q: Can these nickel strips be used for battery types other than 18650?
A: Absolutely. While optimized for 18650 lithium battery packs, these nickel sheets are also compatible with NiMH batteries, polymer batteries, power tool battery packs, combi batteries, and various power battery and electronics applications.
Q: Do the sheets arrive ready to weld, or do they require surface preparation?
A: These nickel strips are fully degreased at the factory, so the surface is smooth and clean straight out of the package — no additional prep needed before spot welding or tin-plating.
