What are Tenergy CR123A Lithium Batteries? Tenergy CR123A Lithium Batteries are high-performance, non-rechargeable 3V batteries designed for devices requiring long-lasting power, such as cameras, flashlights, and medical equipment. Their compact size, leak-resistant construction, and stable voltage output make them ideal for high-drain electronics. The 2-pack offers convenience for users needing immediate replacements.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Do Tenergy CR123A Batteries Compare to Other Lithium Batteries?
Tenergy CR123A batteries outperform standard alkaline batteries with a 10-year shelf life, consistent 3V output, and superior performance in extreme temperatures (-40°C to 60°C). Unlike cheaper alternatives, they use lithium manganese dioxide chemistry for higher energy density, ensuring reliable operation in critical devices like security systems and emergency tools.
When compared to competing lithium models, Tenergy CR123A batteries demonstrate 15% higher capacity retention after 5 years of storage. Independent tests show they maintain 95% of their initial voltage under moderate loads, whereas generic brands drop to 85% within the same period. Their robust construction prevents swelling in humid environments, a common issue with unbranded lithium cells. For professionals using night-vision equipment or tactical gear, this reliability translates to fewer mid-operation battery changes and reduced risk of device failure.
| Feature | Tenergy CR123A | Standard Lithium |
|---|---|---|
| Cold Weather Performance | -40°C Operational | -20°C Limit |
| Leak Resistance | Double-Sealed | Basic Seal |
What Devices Are Compatible with Tenergy CR123A Batteries?
These batteries power high-drain devices, including tactical flashlights, digital cameras, laser pointers, and medical devices like glucose monitors. They’re also used in military-grade equipment and smoke detectors due to their durability. Always check your device’s voltage requirements—CR123A batteries are incompatible with 1.5V electronics unless specified.
Why Choose a 2-Pack Configuration for CR123A Batteries?
The 2-pack ensures users have a backup battery for emergencies, reducing downtime. It’s cost-effective compared to single-unit purchases and simplifies storage. Many devices requiring CR123A batteries use dual-cell setups, making the 2-pack a practical choice for simultaneous replacements.
Are Tenergy CR123A Batteries Safe for Long-Term Storage?
Yes. Their lithium chemistry minimizes self-discharge (less than 2% annually), retaining 90% capacity after a decade. Store them in a cool, dry place at room temperature (20°C). Avoid humid environments to prevent terminal corrosion, and keep batteries in original packaging until use.
How Does Temperature Affect Tenergy CR123A Battery Performance?
Lithium batteries thrive in extreme conditions. Tenergy CR123A operates from -40°C to 60°C, making them suitable for outdoor adventures and industrial settings. Cold temperatures slightly reduce runtime but won’t damage cells, unlike alkalines, which may freeze and leak.
What Certifications Ensure Tenergy CR123A Battery Safety?
Tenergy CR123A batteries meet UL1642, UN38.3, and IEC 60086 standards, ensuring compliance with safety, transportation, and performance benchmarks. These certifications validate their leak resistance, thermal stability, and absence of mercury/cadmium, aligning with eco-friendly disposal guidelines.
The UL1642 certification specifically requires rigorous testing for short-circuit, abnormal charging, and forced discharge scenarios. UN38.3 ensures safe air transport by mandating altitude simulation, thermal cycling, and vibration tests equivalent to 3 hours of intense aircraft turbulence. For industrial users, IEC 60086 guarantees consistent performance metrics across production batches, crucial for maintaining equipment calibration. These certifications collectively ensure that Tenergy batteries meet military-specification (MIL-STD) requirements without the premium pricing associated with defense-contract brands.
| Certification | Focus Area | Relevance |
|---|---|---|
| UL1642 | Electrical Safety | Prevents overheating |
| UN38.3 | Transportation | Air shipping approval |
Can Tenergy CR123A Batteries Be Recycled?
Yes. Lithium batteries are recyclable through certified e-waste programs. Tenergy recommends removing batteries from devices before recycling and using tape to cover terminals to prevent short-circuiting. Retailers like Home Depot and Best Buy offer free drop-off services.
