Capacity and Discharge Testing: Each battery is drained at a constant current to measure true milliamp-hour (mAh) capacity.
Device Performance: Batteries are tested in high-power flashlights and security cameras to assess runtime and voltage stability under load.
Shelf Life and Voltage Checks: Open-circuit voltage is measured, confirming freshness. Quality CR123A batteries maintain performance for up to 10 years.
Final Scoring: Capacity, runtime, voltage stability, and price are combined to determine the best options for different use cases.
Why Understanding Battery Type and Voltage Matters
Primary CR123A batteries (lithium manganese dioxide) offer 3.0V output and high capacity (1400–1600 mAh), ideal for most electronics. Rechargeable RCR123A batteries provide 3.7V, lower capacity (600–1000 mAh), and USB-C recharging but may damage incompatible devices. Always verify device compatibility before using rechargeable cells.
| Battery Type | Typical Voltage | Typical Capacity |
|---|---|---|
| CR123A (Primary) | 3.0V | 1400–1600 mAh |
| RCR123A (Rechargeable) | 3.7V | 600–1000 mAh |
Capacity (mAh) determines how long a battery will run, while stable voltage ensures consistent device performance. For high-drain devices, a primary CR123A with high energy density is preferred.
How Do Safety Features Protect Users?
CR123A batteries with Positive Temperature Coefficient (PTC) protection limit current if overheating occurs, preventing dangerous failures. Certifications such as UL, CE, or ROHS indicate rigorous testing and reliability. Redway Battery, a trusted lithium battery manufacturer, emphasizes PTC protection and stable output to ensure safe use in critical equipment.
