Battery Spring AA Battery Negative to Positive Pole Conversion Spring Contacts Nickel-Plated Using an iron-based substrate + surface nickel-plating process, it offers superior conductivity compared to ordinary iron sheets, with lower resistance, ensuring stable current transmission. It has strong oxidation resistance and is unlikely to rust even with long-term use, preventing equipment failures caused by poor contact. The spring component is made of high-carbon steel, offering durable elasticity and maintaining its shape even after repeated compression. It is suitable for applications such as battery compartment repairs, electronic device modifications, and battery compartment replacements for toys/remote controls. The nickel-plated surface reduces resistance and enhances electrical performance (especially suitable for high-power-consuming devices).
