Duracell CR123A High Power Lithium — Compact 3V Power for High-Drain Devices

The Duracell CR123A High Power Lithium battery is a compact 3-volt powerhouse developed for electronics that demand quick bursts of current and dependable operation. Favored in tactical flashlights, motion sensors, alarm systems, trail cameras, and professional imaging gear, the CR123A balances high pulse capability with strong shelf life and a rugged design. When seconds matter—or when changing batteries frequently is inconvenient—this cell delivers consistent, predictable output you can count on in daily and demanding scenarios.

Why Professionals Trust CR123A

• High-drain readiness: Supports bright flashlight output and fast sensor response.
• Consistent 3V performance: Stable voltage delivery across a broad load range.
• Compact power density: Small form factor with impressive energy for its size.
• Temperature tolerance: Performs reliably across hot/cold swings typical of outdoor and security uses.
• Leak-resistant design: Added confidence for sensitive optics and electronics.

Where CR123A Excels

• Tactical and everyday-carry flashlights
• Security systems, motion detectors, and alarm panels
• Trail cameras and wildlife sensors
• Professional and vintage cameras that specify CR123A
• Smart home devices and compact emergency lights

Technical Overview

• Chemistry: Lithium manganese dioxide (Li-MnO₂)
• Voltage: 3V
• Typical size: Approx. 34–35 mm length × 17 mm diameter (industry CR123A form)
• Designation: CR123A (also known as 123, CR17345 in some specs)

CR123A vs. AA or Rechargeables

AA batteries are longer and typically 1.5V (alkaline) or 1.2V (NiMH). Devices that specify CR123A are engineered around 3V lithium chemistry and high pulse demands. Do not substitute AA or other sizes. Likewise, only use rechargeable RCR123A/16340 cells if your device explicitly supports rechargeables; voltages and discharge curves differ, and using the wrong type can damage electronics.

Installation Steps

1. Verify battery type: Confirm the device calls for “CR123A.”
2. Observe polarity: Match the “+” and “–” orientation indicated inside the compartment.
3. Inspect contacts: Wipe any residue with a dry, lint-free cloth.
4. Close securely: Ensure the cap/door is fully tightened for consistent contact.
5. Function test: Check brightness (for lights) or sensor responsiveness after installation.

Storage, Handling, and Safety

• Store cool and dry: Keep spares in original packaging away from heat sources.
• No loose mixing: Avoid storing with keys or coins to prevent short circuits.
• Primary cell only: CR123A is non-rechargeable. Use rechargeables only if your device is designed for them.
• Keep away from children: Small cells can pose ingestion risks; dispose of depleted batteries promptly.

Maximizing Runtime and Performance

• Use the correct chemistry and size—never mix brands or old/new cells in the same device.
• For flashlights, choose modes wisely: high for bursts, medium/low for extended runtime.
• Protect devices from extreme heat that can accelerate self-discharge.
• Maintain clean contacts to reduce resistance and voltage sag under load.

FAQs

How long does a CR123A last in a flashlight?

It depends on brightness level, driver efficiency, and usage patterns. High-output modes consume more current; medium/low modes significantly extend runtime.

Can I use RCR123A (rechargeable) instead?

Only if the device manual allows it. Rechargeables can have different voltages and discharge characteristics—using them in a device not designed for rechargeables can cause damage.

Is CR123A okay for outdoor or emergency kits?

Yes. It’s a popular choice thanks to compact size, high pulse capability, and reliable performance in varied temperatures.

Summary

Duracell’s CR123A High Power Lithium battery offers compact, high-drain-ready energy for serious gear. Install the specified type, handle correctly, and store spares properly to keep lights bright, sensors responsive, and critical devices ready.
