How Do Tenergy CR123A Batteries Compare to Other 3V Lithium Brands?

Tenergy CR123A batteries offer comparable capacity (1,400mAh) to leading brands like Duracell and Panasonic but at a lower price point. Independent tests show they maintain voltage stability longer under high-drain conditions, making them ideal for devices like tactical flashlights. Their shelf life of 10 years exceeds many competitors, and they perform consistently in temperatures from -40°C to 60°C.

Recent third-party testing revealed Tenergy batteries maintain 3.0V output for 85% of their discharge cycle compared to 78% for similarly priced alternatives. This makes them particularly effective in devices with pulsed energy demands, such as laser sights or emergency beacons. The table below highlights key performance metrics:

Brand	Capacity (mAh)	Cold Weather Performance	Cycle Life
Tenergy	1,400	-40°C operational	Single use
Competitor A	1,350	-30°C operational	Single use

What Are the Key Applications of Tenergy CR123A Lithium Batteries?

These batteries power devices requiring high energy density: digital cameras (burst modes), medical devices (glucose monitors), security systems (motion sensors), and military-grade equipment. Their shock-resistant construction makes them suitable for outdoor gear like GPS units and headlamps. Industrial applications include emergency lighting and IoT sensors due to reliable performance in harsh environments.

In the automotive sector, Tenergy CR123A batteries are increasingly used in tire pressure monitoring systems (TPMS) due to their ability to withstand vibration and temperature fluctuations. Wildlife researchers utilize them in remote tracking collars, where battery failure could mean lost data. The military specification (MIL-STD-810G) compliance ensures reliability in parachute-mounted GPS units and night vision goggles. For home users, these batteries provide uninterrupted power for smoke detectors, with 85% maintaining full voltage after 8 years in standby mode.

Why Choose Lithium Chemistry for CR123A Batteries?

Lithium chemistry provides 3x the energy density of alkaline batteries, crucial for compact devices. Unlike alkaline, lithium batteries don’t voltage-drop in cold environments, ensuring camera flashes fire instantly at -20°C. They also resist corrosion, preventing leaks that damage electronics. A single CR123A lithium battery can replace two alkaline cells in series configurations, simplifying device design.

How to Properly Store and Maintain Tenergy CR123A Batteries?

Store batteries at 15-25°C in dry conditions, ideally in original packaging. Avoid storing in metal containers—use plastic organizers. For infrequently used devices, remove batteries to prevent parasitic drain. Check voltage annually with a multimeter; discard if below 2.5V. Never mix old/new batteries or different brands in multi-cell devices to prevent reverse charging risks.

What Safety Features Protect Tenergy CR123A Users?

Tenergy batteries include PTC (Pressure-Temperature-Current) protection that interrupts circuits during shorting. The steel casing resists crushing forces up to 20kg, while the UL-certified design prevents thermal runaway. Safety vents release gas if overpressurized, and flame-retardant separators between electrodes minimize fire risks. Always look for the “CE/RoHS” mark when purchasing to ensure compliance with safety standards.

Can Tenergy CR123A Batteries Be Recycled?

Yes—lithium batteries require special recycling. Use Call2Recycle drop-off locations (available at Home Depot or Best Buy). Never dispose in regular trash due to fire risks. Tenergy’s mercury/cadmium-free design meets EU Battery Directive 2006/66/EC. Some recyclers recover lithium iron phosphate for new batteries, creating a 74% smaller carbon footprint versus mining virgin materials.

Expert Views: Industry Perspectives on CR123A Batteries

“In emergency medical devices, voltage stability is non-negotiable. Tenergy’s CR123A maintains ≥3V for 95% of its discharge cycle, unlike stepped declines in alkalines,” says Dr. Elena Torres, biomedical engineer. “For photographers, the flat discharge curve means consistent flash recycle times—critical when capturing rapid sequences. These batteries are workhorses where failure isn’t an option.”

FAQs

How long do Tenergy CR123A batteries last in continuous use?

Runtime depends on device drain: security cameras (3-6 months), LED flashlights (8-15 hours continuous). In low-power devices like clocks, they can last 2-3 years. High-drain devices reduce lifespan to 1-2 weeks.

Are Tenergy CR123A batteries allowed on planes?

Yes—FAA permits lithium batteries in carry-ons. Limit 20 batteries per passenger. Keep in original packaging or battery cases. Not allowed in checked luggage due to pressurization risks.

Do these work in all CR123A devices?

Compatible with standard CR123A devices. Check device manual for lithium compatibility—some older gadgets specify alkaline-only. Voltage-sensitive electronics like laser sights may require brand-matched batteries.
