What are non-rechargeable lithium CR123A batteries? These are high-energy, single-use lithium batteries designed for devices requiring stable voltage and long shelf life. Commonly used in cameras, medical devices, and tactical gear, they deliver 3V power with superior performance in extreme temperatures compared to alkaline alternatives. Their non-rechargeable nature ensures reliability in critical applications.

How Do CR123A Lithium Batteries Differ From Rechargeable Options?
Non-rechargeable CR123A batteries use lithium chemistry (LiMnO₂) for one-time use, providing higher energy density and longer shelf life (up to 10 years). Rechargeable alternatives (e.g., RCR123A) use Li-ion tech but offer fewer cycles and lower voltage (3.7V vs. 3V), which may damage devices not designed for them. Non-rechargeables excel in reliability for emergency equipment.

- Industrial sensors (temperature/pressure gauges)
Their compact size and high output make them ideal for high-drain devices requiring instant power bursts. In photography, CR123A batteries power external flashes like the Nikon SB-5000, where rapid recycling times between shots are critical. Medical devices such as portable ECG monitors rely on their stable voltage to ensure accurate readings during emergencies. Industrial applications include wireless sensors in oil refineries, where extreme temperatures (-40°C to 60°C) would render alkaline batteries useless. Tactical gear like night-vision scopes also depends on CR123A’s ability to deliver consistent power during extended field operations without risking recharge failures.
| Device Category | Specific Use Cases | Runtime (Avg.) |
|---|---|---|
| Security Systems | Motion-activated alarms | 12–18 months |
| Medical Equipment | Portable oxygen sensors | 6–9 months |
| Photography | DSLR external flashes | 300–500 cycles |
How to Store and Dispose of CR123A Lithium Batteries Safely?
Store in cool, dry places below 25°C. Avoid puncturing or exposing to fire. Dispose via certified e-waste recyclers—never incinerate. The lithium content can cause hazardous reactions if crushed. Tape terminals before disposal to prevent short-circuiting. Check local regulations; some regions classify them as hazardous waste.
For long-term storage, keep batteries in original packaging or non-conductive containers to avoid contact with metal objects. Humidity above 60% can accelerate corrosion, so consider using silica gel packs in storage areas. Never mix new and used batteries in the same device, as voltage disparities may lead to leakage. Retailers like Home Depot and Best Buy often host battery recycling kiosks, while manufacturers like Panasonic provide prepaid mail-back programs. In Europe, the WEEE Directive mandates free consumer recycling, whereas U.S. states like California require separate disposal labels for lithium batteries.
| Storage Factor | Ideal Condition | Risk if Ignored |
|---|---|---|
| Temperature | 15°C–25°C | Capacity loss above 30°C |
| Humidity | <60% RH | Terminal corrosion |
| Packaging | Non-conductive case | Short-circuiting |
Frequently Asked Questions
- Can CR123A batteries be used interchangeably with 16340 cells?
- No. Though similar in size, 16340 cells are rechargeable Li-ion (3.7V) and risk damaging devices designed for 3V CR123A.
- Do CR123A batteries explode if overheated?
- Extreme heat (>100°C) can cause rupture. Avoid direct sunlight or enclosed spaces like hot cars. Most have built-in vents to release pressure safely.
- Are CR123A batteries allowed on airplanes?
- Yes, in carry-ons. FAA permits up to 20 spare cells. Installed in devices, they’re unrestricted. Declare them at security checks.
