SPIDER Automation | CR2032 / CR2025 Coin Cell Battery Holder | 3V PCB Mountable Battery Socket
Product Overview
The SPIDER Automation CR2032 / CR2025 Coin Cell Battery Holder is a compact battery socket designed for mounting compatible 3V lithium coin cell batteries in electronic circuits and PCB-based projects. It provides a dedicated mounting position for coin cells, making battery installation and replacement convenient in compact electronic assemblies.
Designed for CR2032 and CR2025 battery formats, this holder features a metal and plastic construction and is intended for direct soldering onto a compatible printed circuit board (PCB). Its compact form factor makes it useful in space-conscious electronic designs that require a removable coin-cell power source.
With an approximate 25mm body diameter and 8.5mm height, this lightweight battery socket can be incorporated into experimental circuits, small robots, toys and other low-power electronic applications requiring a compatible 3V coin cell.
Technical Features & Construction
- CR2032 / CR2025 Compatibility: Intended for holding compatible lithium coin-cell battery formats.
- 3V Battery Applications: Suitable for electronic circuits designed around 3V lithium coin cells.
- PCB-Mountable Design: Designed to be soldered directly onto a compatible PCB.
- Metal and Plastic Construction: Combines metal and plastic components in a compact holder assembly.
- Compact Dimensions: Approximately 25mm in body diameter and 8.5mm in height.
- Lightweight Structure: Approximate individual holder weight of 1g.
- Replaceable Battery Arrangement: Provides a holder-based mounting solution rather than requiring the coin cell to be permanently soldered into the circuit.
- Simple Circuit Integration: Useful in PCB layouts that incorporate a compatible coin-cell power source.
Battery Compatibility & Electrical Details
This holder is described for use with CR2032 and CR2025 3V lithium coin cells. These battery formats are commonly used in compact electronic circuits where a small, replaceable power source is required.
- CR2032: A 3V lithium coin cell with a nominal diameter of approximately 20mm and thickness of 3.2mm.
- CR2025: A 3V lithium coin cell with a nominal diameter of approximately 20mm and thickness of 2.5mm.
- Battery Replacement: The holder provides a mounting arrangement for installing and replacing a compatible coin cell.
- Capacity Reference: The supplier lists 160mAh for the CR2025 battery type; this is not a capacity rating of the holder itself.
Important: Confirm the holder’s contact arrangement and mechanical fit before finalising the PCB footprint. Battery capacity and operating life depend on the selected coin cell and the connected circuit’s current consumption.
PCB Mounting & Circuit Integration
The holder is intended for direct PCB soldering, allowing it to be incorporated into electronic circuit boards that require a coin-cell battery position. It can be used in custom PCB designs, experimental circuit boards and compact electronic assemblies.
- PCB Installation: Position the holder according to its actual terminal layout and solder it to compatible PCB pads.
- Footprint Planning: Account for the holder’s approximate 25mm body diameter and 8.5mm height when planning component placement.
- Battery Access: Allow sufficient clearance for inserting and removing the coin cell.
- Electrical Connections: Match the PCB contact layout with the holder’s actual positive and negative terminals.
- Mechanical Clearance: Ensure nearby components do not obstruct battery installation or removal.

PCB Integration & Operating Recommendations
- Check Battery Compatibility: Use a CR2032 or CR2025 coin cell only after confirming the holder’s actual mechanical fit and contact arrangement.
- Verify PCB Footprint: Confirm terminal positions and pad dimensions from the physical holder before designing or ordering a PCB.
- Observe Polarity: Match the battery’s positive and negative sides with the holder terminals and circuit polarity markings.
- Provide Battery Clearance: Keep enough space around the holder for convenient battery insertion and replacement.
- Use Suitable Soldering Practices: Apply appropriate soldering temperature and technique to avoid damaging the plastic body or metal contacts.
- Check Circuit Requirements: Ensure the connected electronics are designed for the nominal 3V coin-cell supply.
- Avoid Short Circuits: Prevent tools, loose wires or conductive objects from bridging the battery contacts.
