This coin cell retainer, commonly called a battery clip, is engineered to securely hold and provide reliable electrical contact for LR43, AG12, 386, and 301 cell types. Designed for through-hole PCB mounting, it offers a stable and permanent installation for your electronic assemblies. The clip is manufactured from durable spring steel, ensuring consistent clamping force and long-term mechanical resilience to withstand repeated battery changes. A corrosion-resistant nickel plating enhances conductivity, minimizes contact resistance, and protects against oxidation for extended service life. Its straightforward design allows for easy battery insertion and removal while maintaining a firm grip to prevent dislodgment due to vibration or movement. This component is an ideal, industry-standard solution for powering compact devices such as calculators, watches, medical instruments, and memory backup circuits, providing a dependable and solderable connection point directly to your printed circuit board.
