FAQ

Q1: Are these spacers compatible with both anode and cathode sides of the coin cell?
A1: Yes, they can be used on either side to maintain proper spacing and internal contact pressure.

Q2: What material grade is used?
A2: They are manufactured from high-grade 304 stainless steel, providing excellent strength and corrosion resistance.

Q3: Can these spacers be reused?
A3: Yes. With proper cleaning and handling, they can be reused multiple times without deformation.

Q4: Are springs required for coin-cell assembly?
A4: In most cases, yes. Springs are used in conjunction with spacers to maintain consistent internal pressure.

Q5: Do these spacers affect electrochemical performance?
A5: No. They are chemically inert and mechanically stable, ensuring consistent testing conditions.
