Negative Bottom

A high-precision, multi-layered metal disk engineered as the negative terminal and structural base cap for high-performance alkaline batteries.

• Optimized Electrical Conductivity: Formulated with premium copper or nickel-plated steel alloys to ensure low contact resistance and stable current output.
• Superior Leak Protection: Designed with tight dimensional tolerances to form an airtight, mechanical seal with the safety gasket, effectively preventing electrolyte leakage.
• Excellent Corrosion Resistance: Features a specialized protective plating that resists oxidation and electrochemical degradation over long-term storage and discharge cycles.
