What is SS304 Coin Cell Battery Spacer?

SS304 Coin Cell Battery Spacers are precision-made stainless steel components primarily used in coin cell batteries (e.g., CR2032, CR2025). These spacers are fabricated from 304 stainless steel (SS304), known for its superior corrosion resistance, mechanical durability, and reliable conductivity. SS304 spacers ensure consistent cell compression, improved electrical contact, and long-term battery performance.
