Product details

Introducing our premium Dual M/F Battery Contacts, specifically engineered to accommodate both ‘A’ and ‘AA’ size batteries in a single, versatile design. These contacts feature one male (positive) and one female (negative) terminal per set, creating a reliable series connection for dual-battery configurations. Ideal for high-end flashlights, medical devices, portable instruments, and DIY electronics, this dual-format design eliminates the need for separate contact parts. The contacts are precisely stamped from high-conductivity nickel-plated steel, ensuring stable voltage transfer and low internal resistance. Whether you are an engineer building a prototype or a hobbyist repairing a device, these contacts offer a perfect balance of functionality and durability, with spring tension optimized for standard ‘A’ and ‘AA’ cell dimensions.

Constructed from 0.3mm thick phosphor bronze with a triple-layer nickel coating, these contacts resist corrosion, oxidation, and repeated compression cycles. The male contact features a raised dimple with a pointed tip to ensure positive engagement with the battery’s positive cap, while the female contact is designed as a wave-form spring that maintains constant pressure on the battery’s negative terminal. The dual-purpose design includes locating pins and PCB mounting feet for secure soldering and mechanical retention. Each contact has a maximum current rating of 3A continuous and can withstand over 10,000 insertion cycles without significant fatigue. The formed edges are burr-free, protecting battery wraps and preventing short circuits. This robust construction guarantees consistent performance in temperature ranges from -20°C to +80°C.

These dual M/F contacts simplify battery compartment layouts by reducing the number of unique parts required. One immediate application is converting single-battery devices to dual-battery operation for extended runtime or higher output. They are also ideal for series connection setups where two 1.5V cells need to generate 3V. Installation is straightforward: align the contacts with the molded slots in your battery case or PCB, solder the leads, and snap in the batteries. The dual ‘A’/’AA’ compatibility means you can design a single product that accepts either battery type without tooling changes. For maintenance, the smooth contact surfaces minimize arcing and sparking. Upgrade your power interface today with these reliable, easy-to-assemble contacts that deliver professional-grade electrical performance in any portable device design.
