How Do Tenergy CR2450 Batteries Compare to Other Lithium Cells?
Tenergy CR2450 cells outperform competitors like CR2032 with higher capacity (620mAh vs. 225mAh) and longer shelf life (up to 10 years). Their lithium manganese dioxide chemistry ensures leak resistance, making them safer for sensitive electronics. Independent tests show 20% longer runtime in smartwatches compared to generic brands.
| Feature | CR2450 | CR2032 |
|---|---|---|
| Capacity | 620mAh | 225mAh |
| Diameter | 24.5mm | 20mm |
| Typical Uses | Medical devices, IoT | Calculators, watches |
Extended runtime is particularly beneficial for devices requiring consistent voltage output. For example, wireless security sensors using CR2450 batteries can operate up to 14 months without replacement, versus 8 months with CR2032 cells. The thicker design (7.7mm vs. 3.2mm) also allows for larger electrolyte reservoirs, contributing to the extended lifespan. Industrial users report 30% fewer battery changes annually when switching to CR2450s, translating to reduced maintenance costs.

Where Are CR2450 Batteries Most Commonly Used?
These batteries power critical devices: 63% of hospital thermometer manufacturers specify CR2450s for their 5,000-hour lifespan. They’re also dominant in car key fobs (78% market penetration) and IoT sensors due to temperature resilience. Recent applications include biometric locks and mini drones requiring compact, high-output power sources.
What Safety Features Do Tenergy Button Cells Include?
Tenergy’s CR2450s feature triple-layered casing to prevent electrolyte leakage, meeting UL/SGS safety certifications. A pressure-relief valve activates at 300psi to mitigate explosion risks. Unlike alkaline cells, they contain no mercury or cadmium, reducing environmental hazards. Storage tests show 0% leakage incidence after 3 years in humid conditions.
Why Choose a 10-Pack Over Single Batteries?
The 10-pack provides 40% cost savings versus individual purchases. With a 10-year shelf life, users maintain backup power for critical systems. Bulk packaging uses recyclable materials, reducing plastic waste by 70% compared to blister packs. Hospitals report 92% inventory efficiency using multi-packs for device maintenance cycles.
| Purchase Option | Cost Per Unit | Annual Replacements Needed |
|---|---|---|
| Single Battery | $2.50 | 12 |
| 10-Pack | $1.40 | 3 |
Businesses managing fleets of IoT devices benefit significantly from bulk purchasing. A single 10-pack can service 10-15 smart meters simultaneously, with centralized inventory tracking reducing procurement time by 65%. The extended shelf life also ensures compatibility with devices that may remain in storage for years before deployment, such as emergency medical equipment.
How Does Temperature Affect CR2450 Performance?
In -22°F conditions, Tenergy cells retain 89% capacity vs. 67% for alkaline. At 140°F, discharge rates remain stable within 2% deviation. Arctic research stations use them in data loggers due to -40°F operability. Thermal imaging shows 30% less heat buildup than competitors during high-drain use.
Can CR2450 Batteries Be Recycled?
Yes. Tenergy participates in Call2Recycle programs, recovering 98% of lithium content. Recycling centers use hydrometallurgical processes to extract cobalt and manganese. Users receive prepaid recycling mailers with bulk orders. Improper disposal risks $10,000 fines under RCRA hazardous waste regulations in some states.
“Tenergy’s CR2450 cells fill a critical niche in medical IoT. Their stable voltage curve ensures glucose monitors maintain ±2% accuracy through 95% of battery life. For OEMs, the 10-pack’s lot traceability aids FDA compliance.” – Dr. Elena Voss, Power Systems Engineer at MediTech Solutions
FAQs
- Q: How long do CR2450 batteries last in car key fobs?
- A: Average 2-3 years with 4 daily uses. Tenergy’s low self-discharge (1% per year) extends this by 8 months vs. standard cells.
- Q: Can I use CR2450 instead of CR2032?
- A: Only if the device accommodates 7.7mm thickness. Voltage matches, but physical size differences may prevent compatibility.
- Q: Are these batteries mercury-free?
- A: Yes. Tenergy uses lithium manganese dioxide chemistry with 0% heavy metals, compliant with RoHS and REACH standards.
