Product Information
Full details
The Switch Electronics CR2450 Coin Cell PCB Battery Holder is an essential component for engineers and DIY electronics hobbyists who need a reliable, secure way to integrate CR2450 batteries into custom printed circuit boards. It offers a stable, low-profile mounting solution that ensures consistent power delivery for real-time clocks, memory backup, and small sensors. While it provides excellent mechanical retention, users should note that its fixed footprint requires careful planning during the board design phase to ensure sufficient clearance for the 29.6mm diameter housing.

FAQs
Can this holder accommodate other battery sizes like CR2032?
No, this holder is designed exclusively for the dimensions of the CR2450 battery.
Is this holder suitable for surface mount (SMD) technology?
This specific model is designed for PCB through-hole mounting.
What is the total height of the unit when a battery is installed?
The holder itself is 9.2mm high; the battery will sit within this housing, maintaining a total height just slightly above 9mm.
Are there specific temperature constraints for soldering?
Standard soldering temperatures are acceptable, but avoid prolonged direct contact with the plastic housing to prevent melting.
Does this holder include a battery?
No, the battery is sold separately.
Troubleshooting
Intermittent power supply to the circuit
Check for oxidized battery contacts or residual solder flux on the terminals; clean with isopropyl alcohol.
Battery does not fit securely
Verify the battery is a genuine CR2450 type; check the holder for any physical damage or bent retaining clips.
Holder pins do not align with PCB holes
Verify your PCB footprint design matches the 20.3mm pitch requirement before assembly.
Pros and Cons
Pros
- Reliable mechanical retention for battery security
- Low-profile design saves internal vertical space
- Easy to solder into standard PCB footprints
- High-quality, stable electrical contact points
Cons
- Requires precise PCB hole spacing for installation
- Not intended for hot-swapping in high-vibration environments
- Fixed footprint occupies significant board surface area
Setup, Compatibility & Care
To install the holder, align the mounting pins with the corresponding through-holes on your PCB according to the 20.3mm pitch specification. Ensure you use a standard soldering iron or wave soldering process; avoid excessive heat to prevent deformation of the plastic housing. Once soldered, the holder is maintenance-free, though it is recommended to keep the contact surface clean of flux residue for optimal connectivity. When replacing batteries, use a non-conductive tool to gently pry the cell from the holder to avoid shorting the contacts.
