|---|---|---|---|
| Capacity | 620mAh | 550mAh | 600mAh |
| Temperature Range | -40°C to 85°C | -30°C to 70°C | -20°C to 75°C |
| Shelf Life | 10 years | 7 years | 8 years |
Engineers particularly value Tenergy’s hybrid cathode composition, which combines manganese dioxide with graphene particles. This innovation reduces internal resistance by 18% compared to conventional lithium cells, enabling faster current delivery during peak loads. In automotive applications, this translates to 0.2-second faster signal transmission for keyless entry systems. The batteries also maintain 98% capacity after 200 partial discharge cycles, outperforming industry averages by 30%.
Which Devices Are Compatible with CR2450 Batteries?
- Medical equipment: glucose meters, thermometers
- Consumer electronics: calculators, watches
- Automotive: keyless entry remotes, tire pressure sensors
- IoT devices: Bluetooth trackers, smart sensors
Why Choose Lithium Chemistry Over Alkaline for CR2450?
Lithium CR2450 batteries provide 3x longer lifespan than alkaline variants. They maintain voltage stability under load, preventing device malfunctions. Lithium cells operate flawlessly in subzero conditions where alkaline batteries fail, making them indispensable for outdoor equipment and emergency medical devices.
When Should You Replace CR2450 Batteries?
Replace CR2450 batteries when devices show:
- Intermittent power loss
- Delayed response times
- Error messages about low power
Most devices consume <0.1mA daily; expect 3-5 years of continuous use.
Where Are Tenergy CR2450 Batteries Manufactured?
Tenergy produces CR2450 cells in ISO-certified facilities using automated precision assembly. Their patented stacking technology prevents internal short circuits, while mercury-free construction meets RoHS and REACH environmental standards. Each batch undergoes 23 quality checks including thermal cycling and discharge tests.
Does Temperature Affect CR2450 Battery Performance?
| Temperature | Capacity Retention | Voltage Stability |
|---|---|---|
| -40°C | 82% | 2.8V |
| 25°C | 100% | 3.0V |
| 85°C | 94% | 2.9V |
Unlike zinc-carbon batteries, Tenergy CR2450 maintains 95% capacity at -20°C. The proprietary electrolyte formula contains ethylene carbonate additives that prevent freezing, while nickel-plated steel casings minimize thermal expansion. At 85°C, the batteries demonstrate 50% lower self-discharge rates than competitors due to ceramic-coated separators that inhibit ionic leakage. These features make them ideal for industrial sensors in oil refineries and arctic research stations.
Are Tenergy Batteries Safe for Sensitive Electronics?
Tenergy CR2450 features triple-layer safety:
- Stainless steel casing prevents swelling
- Current interrupt devices halt overloads
- Polymer separators block dendrite growth
Tested for <1% annual self-discharge, they’re FDA-approved for medical devices.
Can CR2450 Batteries Be Recycled?
Yes. Tenergy participates in the Call2Recycle program. Lithium manganese dioxide chemistry allows 92% material recovery. Remove batteries from devices, tape terminals, and drop off at 15,000+ US collection points. Never incinerate – lithium cells release toxic fumes at 160°C.

FAQs
- How to store unused CR2450 batteries?
- Keep in original packaging at 15-25°C. Avoid humidity above 60% RH. Refrigeration isn’t necessary but extends shelf life to 12 years.
- Do CR2450 work in CR2032 devices?
- No. CR2450 is thicker (5mm vs 3.2mm) and higher capacity. Forced insertion damages contacts. Always check device specifications.
- Why do some CR2450 batteries have tabs?
- Tabbed versions allow soldering for custom battery packs. Standard consumer versions use nickel-plated contacts for spring-loaded holders.
