The CR2450 rechargeable lithium coin cell battery is a high-capacity, compact power source designed for devices requiring long-lasting energy. Unlike standard lithium batteries, it offers rechargeability, reducing waste and costs. With a voltage of 3V and capacity up to 620mAh, it’s ideal for medical devices, IoT sensors, and wearables. Its lithium chemistry ensures stable voltage output and a lifespan of 500+ cycles.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does the CR2450 Compare to Non-Rechargeable Coin Cells?
The CR2450 rechargeable variant outperforms non-rechargeable counterparts like the standard CR2450 by offering up to 620mAh capacity and 500+ recharge cycles. Non-rechargeable cells have higher initial capacity (up to 900mAh) but cannot be reused, leading to higher long-term costs. Rechargeable versions maintain stable voltage longer, making them preferable for devices requiring consistent power over time.
| Feature | Rechargeable CR2450 | Standard CR2450 |
|---|---|---|
| Cycle Life | 500 cycles | Single use |
| Cost Over 5 Years | $12-18 | $45-60 |
| Voltage Stability | ±2% deviation | ±8% deviation |
What Safety Features Do CR2450 Rechargeable Batteries Include?
Rechargeable CR2450 batteries incorporate built-in protection against overcharge, short circuits, and overheating. Advanced models include pressure relief vents and thermal cutoff switches. Lithium manganese dioxide (Li-MnO2) chemistry minimizes leakage risks. Users must avoid puncturing or exposing cells to temperatures above 60°C (140°F) to prevent thermal runaway.

Modern variants employ multi-layered safety architectures including separator shutdown membranes that block ion flow at 130°C. Some manufacturers now integrate chip-based protection circuits that:
- Monitor real-time temperature fluctuations
- Limit charge current during voltage spikes
- Automatically disconnect during deep discharge (below 2V)
Third-party testing reveals these batteries can withstand 50G mechanical shock and maintain functionality at 85% relative humidity. However, users should still avoid stacking multiple cells without proper insulation due to potential arc-over risks.
What Innovations Are Shaping CR2450 Battery Technology?
Recent advancements include solid-state electrolytes for improved safety and energy density. Graphene-enhanced anodes enable faster charging (30 minutes for 80% capacity). Smart batteries with integrated NFC chips now report remaining charge and cycle count. Researchers are developing biodegradable casings to address recycling challenges in micro-electronics.
Emerging technologies like lithium-silicon nanocomposite cathodes promise 40% capacity improvements while maintaining the same 24.5mm diameter. Wireless charging compatibility is being tested through electromagnetic resonance coupling, potentially eliminating physical connectors. A 2023 breakthrough in photo-rechargeable cells allows certain CR2450 models to harvest energy from ambient light using integrated perovskite solar layers.

FAQ
- How long does a CR2450 rechargeable battery last per charge?
- A fully charged CR2450 provides 600-620mAh, lasting 6-12 months in devices like thermometers or key fobs. High-drain devices may require monthly charging.
- Are CR2450 and DL2450 batteries interchangeable?
- Yes—DL2450 is a non-rechargeable alternative with identical dimensions (24.5mm diameter, 5mm height) and voltage (3V). Always verify device compatibility before substituting.
- Can I solder wires directly to a CR2450 battery?
- Soldering risks overheating and damaging the cell. Use pre-tabbed batteries with welded nickel connectors or battery holders for secure connections.
- What does the “CR” in CR2450 stand for?
- “CR” denotes lithium manganese dioxide chemistry. The numbers indicate size: 24=24.5mm diameter, 50=5.0mm height.
