CR2032 / CR2025 Coin Battery Socket Holder (2 Pieces)

The CR2032 / CR2025 Coin Battery Socket Holder (2 Pieces) is a high-quality PCB-mount battery holder designed to securely accommodate CR2032 and CR2025 3V lithium coin cell batteries. It provides a safe, reliable, and convenient method for powering low-current electronic circuits while allowing quick and easy battery replacement without soldering directly to the battery.

Manufactured from durable, flame-resistant insulating plastic with high-quality corrosion-resistant metal contacts, the battery holder ensures excellent electrical conductivity, low contact resistance, and a secure mechanical grip on the battery. The spring-loaded contact design maintains consistent pressure on the battery terminals, ensuring stable power delivery even in applications subject to vibration or movement.

Designed for through-hole PCB mounting, the holder can be easily soldered onto printed circuit boards, making it suitable for both prototype development and commercial electronic products. Its compact size minimizes PCB space while providing reliable battery retention and long service life.

The CR2032 / CR2025 Coin Battery Socket Holder is widely used in Arduino, ESP32, ESP8266, Raspberry Pi, STM32, RTC (Real-Time Clock) modules, CMOS memory backup circuits, wireless sensor nodes, IoT devices, medical instruments, calculators, digital clocks, remote controls, electronic meters, security systems, embedded systems, robotics, and DIY electronics projects. It is ideal for applications that require a dependable backup power source or standalone battery operation.

Whether you are designing a new PCB, repairing electronic equipment, building an embedded system, or creating battery-powered devices, this battery holder provides a durable, reliable, and user-friendly solution for mounting CR2032 and CR2025 lithium coin cells.

Working Principle

The CR2032 / CR2025 Coin Battery Socket Holder securely holds a lithium coin cell battery using spring-loaded metal contacts that maintain constant pressure against the battery terminals.

When the battery is inserted into the holder, the positive and negative terminals make firm electrical contact with the metal connectors, allowing power to flow to the connected circuit. The holder is soldered directly onto the PCB, providing a stable electrical connection while allowing the battery to be removed and replaced easily whenever necessary.

This design eliminates the need for soldering directly to the battery, reducing the risk of battery damage and making maintenance quick and convenient.
