Buying Guide – How to Choose the Best CR123A Batteries
Choosing the right CR123A battery requires understanding key factors like capacity, temperature range, and device compatibility. This guide breaks down what matters.
Capacity and Voltage
All CR123A batteries operate at 3.0V but vary in capacity typically between 1500mAh and 1700mAh. Higher capacity means longer run time in high-drain devices.
Prioritize capacity for devices like flashlights or cameras that draw power quickly.
Shelf Life
Look for batteries with a 10-year shelf life for emergency kits. This ensures power remains available when you need it most.
Choose brands like Duracell or SureFire that offer guaranteed storage stability.
Temperature Range
If you store batteries in vehicles or outdoors, check operating temperatures. Many lithium cells work from -40°F to 185°F.
Ensure the battery tolerates your environment to avoid failure.
Compatibility
Check if the battery replaces CR123, 123A, or 5018LC. Some models fit a wider range of devices.
Confirm compatibility with your specific smoke alarms or cameras.
Price and Pack Size
Prices vary significantly by pack size. Buying 12-packs often reduces the cost per cell compared to 2-packs.
Buy bulk only if you use the batteries regularly to avoid expiration.
Safety Certifications
Look for UL, CE, or IEC60086-4 certifications. These ensure the battery is tested for safety against leakage.
Avoid uncertified third-party brands for critical devices like smoke alarms.
Rechargeable vs Non-Rechargeable
