CR2032 Coin Cell Battery Holder – PCB Mount 3V Button Cell Battery Socket Connector for DIY Electronics & Microcontrollers in Pakistan

Overview

When designing custom microcontroller boards, real-time clock (RTC) modules, remote controls, or compact wearable electronics, maintaining a steady backup power source without taking up valuable space is essential. The CR2032 Coin Cell Battery Holder is a low-profile, surface or through-hole mount socket designed specifically to secure standard 3V lithium coin cells. Featuring robust spring-steel contacts and a secure retaining clip, this holder ensures reliable electrical connection and prevents the battery from shaking loose under movement or vibration, while allowing quick and tool-free battery replacement when needed.

Key Features

• Secure Retention Clip: Keeps the CR2032 coin cell firmly in place against shock and vibration while maintaining constant spring tension.

• Low-Profile Design: Minimizes height clearance on PCBs, making it ideal for compact enclosures and slim electronic gadgets.

• Reliable Contact Pins: Gold or nickel-plated contact terminals ensure low electrical resistance and prevent corrosion over time.

• Easy Replacement: Allows users to slide old batteries out and slip new ones in effortlessly without requiring desoldering.

Technical Specifications

Common Applications

• Real-Time Clock (RTC) Modules: Essential backup power socket for keeping time accurate on Arduino, Raspberry Pi, and ESP32 projects.

• Compact Remote Controls: Used in wireless key fobs, custom macro pads, and home automation remotes.

• Wearable & Educational Electronics: Power small LED badges, handheld mini gadgets, and student experimental circuits.

• Note to customers: Ensure proper polarity matching (+ side facing upward/outward as marked on the holder) when inserting your CR2032 cell!
