How Do Tenergy CR123A Batteries Compare to Other Brands?
Tenergy CR123A batteries outperform competitors with superior energy density, stable voltage output, and extended shelf life. Independent tests show they last 20% longer in high-drain devices compared to alkaline alternatives. Their brass-top construction minimizes internal resistance, ensuring consistent performance in extreme temperatures (-40°C to 60°C).
When comparing runtime metrics, Tenergy maintains 3.0V for 85% of its discharge cycle versus 72% for generic lithium brands. In pulsed-load applications (like strobe lights), they deliver 12.5A peak current versus 10A maximum from most competitors. This performance advantage stems from:

Why Choose Lithium Chemistry for High-Drain Electronics?
Lithium CR123A batteries provide 1,500 mAh capacity with minimal voltage drop under load. Their chemistry enables rapid current delivery crucial for LED flashlights and digital shutters. Unlike alkaline, lithium cells maintain 95% capacity at -20°C, making them indispensable for outdoor/emergency equipment.
The molecular stability of lithium manganese dioxide (Li-MnO₂) chemistry allows these batteries to handle sudden power surges up to 15A without damage. This makes them particularly effective in:
- Emergency beacons requiring instant activation
- High-speed camera flashes needing millisecond response
- Tactical equipment where power reliability impacts safety
In thermal imaging tests, lithium cells showed 40% less internal heating than nickel-based alternatives during 2C discharge rates. This thermal efficiency directly translates to longer device runtime and reduced risk of battery compartment damage.
How to Store CR123A Batteries for Maximum Shelf Life?
Store in airtight containers at 15-25°C with 50% relative humidity. Keep original packaging to prevent terminal contact. Rotate stock using FIFO (First In, First Out) method. Avoid refrigeration—condensation risks damage. Proper storage preserves the 10-year shelf life with less than 2% annual charge loss.
“Tenergy’s CR123A cells fill a critical niche in professional power systems. Their focus on stable discharge curves makes them preferable for medical devices where voltage consistency is non-negotiable. The brass-topped terminals show smart engineering—they resist corrosion better than standard steel contacts in humid environments.” — John Carlisle, Power Systems Consultant
FAQs
- Are Tenergy CR123A batteries rechargeable?
- No—these are primary (non-rechargeable) cells. Attempting to recharge them may cause leakage or rupture.
- Do they include expiration dates?
- Yes—manufacture dates are laser-etched. Add 10 years for expiration under proper storage.
- Can I use these in air travel?
- FAA allows lithium batteries in carry-ons. For 12-pack quantities, declare them at security checkpoints.
