How Does the Tenergy CR123A Compare to Alkaline Batteries?
Tenergy CR123A lithium batteries outperform alkaline equivalents with a 3V voltage (vs. 1.5V) and superior performance in temperatures from -40°C to 60°C. They maintain 90% capacity after 5 years of storage, unlike alkaline batteries that degrade faster. Lithium chemistry prevents leaks, reducing device damage risks.
| Feature | CR123A Lithium | Alkaline AA |
|---|---|---|
| Voltage Stability | ±2% over discharge cycle | 20% drop at 50% capacity |
| Cold Weather Performance | 85% capacity at -30°C | 15% capacity at -10°C |
| Continuous High Drain | 2A for 45 minutes | 0.5A for 15 minutes |
In practical applications, lithium CR123A batteries demonstrate remarkable consistency. When powering a 1000-lumen flashlight, lithium cells maintain full brightness for 90% of their discharge cycle, while alkaline equivalents dim progressively. This flat discharge curve is critical for medical devices requiring stable voltage. Field tests show lithium batteries provide 3x more shots in professional camera flashes compared to alkaline alternatives, with faster recycle times between flashes.

What Environmental Factors Affect CR123A Performance?
High humidity (>85% RH) accelerates lithium salt formation on terminals. At altitudes above 3000m, reduced atmospheric pressure causes 5-7% capacity loss. Tenergy’s hermetic stainless steel casing prevents altitude-induced leaks. For marine environments, apply dielectric grease to contacts to combat salt corrosion.
Extreme temperature cycling presents unique challenges. When batteries move between -40°C storage and 60°C operational environments, Tenergy’s dual-layer separator prevents electrolyte crystallization. Industrial users in desert climates report 98% reliability over 3-year deployments. For arctic researchers, the batteries’ instant cold-start capability ensures emergency beacons function even after months in frozen conditions. Proper storage in climate-controlled environments (20-25°C) with 40-60% RH maximizes shelf life while minimizing environmental degradation risks.
Why Choose Lithium Chemistry Over Other Battery Types?
Lithium CR123A batteries provide 1500mAh capacity with stable voltage curves, unlike NiMH rechargeables that suffer from memory effect. They operate at 95% efficiency in sub-zero conditions where alkaline batteries fail. Non-toxic lithium iron disulfide composition meets FAA transport regulations for safer shipping.

FAQs
- How long do Tenergy CR123A batteries last in continuous use?
- In a 300-lumen flashlight, expect 4.5 hours runtime. Security cameras average 45 days with motion-activated recording.
- Do these batteries work in cold climates?
- Yes. Tested to deliver 85% capacity at -35°C, outperforming alkaline batteries which fail below -18°C.
- Are they compatible with rechargeable devices?
- No. CR123A are primary cells. Use Tenergy RCR123A Li-ion batteries (3.7V) for rechargeable needs.
