Duracell CR2450 Lithium Coin Battery — High-Capacity 3V Power for Demanding Devices

The Duracell CR2450 lithium coin battery delivers robust 3-volt power in a larger, thicker format that suits higher-drain electronics and applications that require longer runtime between changes. With a 24 mm diameter and 5.0 mm thickness, the CR2450 packs more capacity than slimmer coin cells, making it a preferred choice for bike computers, professional instruments, medical devices (as specified), select keyless entry remotes, and compact LED beacons. If your device calls for “CR2450,” you’ll benefit from endurance, stable output, and confidence in day-to-day use.

Why Choose the CR2450?

• High energy reserve: Larger format supports extended runtimes for higher demands.
• Steady 3V delivery: Helps sensors, transmitters, and indicators operate predictably.
• Wide application range: From health tech to outdoor gear, it thrives where reliability matters.
• Temperature resilience: Performs consistently in typical hot/cold swings, including vehicle remotes and outdoor accessories.
• Leak-resistant build: Added peace of mind for sensitive, expensive electronics.

Typical Uses

• Bike computers and performance sensors
• Automotive remotes and access systems designed for CR2450
• Medical instruments and monitors (per device manufacturer)
• LED safety markers, beacons, and compact lights
• Smart home sensors and niche industrial tools

Technical Details

• Chemistry: Lithium manganese dioxide (Li-MnO₂)
• Voltage: 3V
• Dimensions: 24 mm diameter × 5.0 mm height
• Form factor: CR2450

CR2450 vs. CR2430

Both share the same 24 mm diameter, but the CR2450 is thicker (5.0 mm) and typically offers more capacity than the CR2430 (3.0 mm). If your device is designed for CR2450, using a thinner cell may cause weak contact, shorter life, or immediate shutoff. Always follow the size specified by your device for best results.

Installation Checklist

1. Confirm the size: Look for “CR2450” on the old battery or device manual.
2. Observe polarity: Match the “+” marking with the device diagram.
3. Inspect contacts: Clean any residue with a dry, lint-free cloth for a solid electrical path.
4. Seat the cell: Ensure the coin sits flat and doesn’t rock; fully close the compartment.
5. Test under load: For beacons or lights, verify brightness and activation latency.

Storage and Safety Guidance

• Keep packaged: Store spares in original packaging in a cool, dry place.
• Avoid loose storage: Do not store with loose metal objects that could short the cell.
• Child-safe practices: Coin cells pose ingestion risks. Keep out of reach and dispose of used cells promptly.
• Non-rechargeable: CR2450 is a primary cell; only use rechargeables if your device explicitly requires them.

Optimizing Runtime

• Use the exact size and chemistry specified by the manufacturer.
• Reduce unnecessary alerts, beeps, or lights if the device allows customization.
• Power down when not in use, where applicable.
• Keep contact surfaces clean for minimal resistance.

FAQs

How long does a CR2450 typically last?

It depends on device load and duty cycle. Compared to thinner 24 mm cells, CR2450 generally offers longer runtime, especially in devices with periodic high current bursts.

Can I swap a CR2450 for a CR2430?

No. While the diameter is the same, the thickness and capacity are different. Use the size your device specifies to ensure proper contact and performance.

Is this battery suitable for outdoor equipment?

Yes—within normal environmental ranges, it’s a strong choice for outdoor sensors and accessories that require dependable 3V power.

Summary

Duracell’s CR2450 provides high-capacity, steady 3V power in a durable coin format. Choose it for devices that demand longer life, confident activation, and reliable day-to-day performance.
