- Detailed discharge specifications
- Clear standard and pulse ratings
- Specified operating temperature
- Exact physical dimensions
Cons
- Lower customer rating
- More technical than casual buyers need
We may earn a commission when you buy through this link, at no additional cost to you.
The standard continuous drain is listed as 20mA, while maximum continuous discharge is 1,000mA at 20°C. A typical pulse rating of 900mA uses a three-second on, 27-second off pattern. These figures make it easier to compare the battery with a device's expected current draw rather than relying only on capacity.
The physical measurements are 17.0 millimeters in diameter and 34.5 millimeters in height, with a weight of approximately 16 to 17 grams. The operating temperature is listed as -40°C to +70°C. These details are especially helpful when checking clearance, compartment fit, or environmental limits in a professional device.
This is the best pick for engineers, technicians, and technically informed buyers who need published discharge and dimensional data. Its 4.5 rating is not the highest, and casual users may find the specification sheet less approachable, but the transparency makes it valuable for exact compatibility decisions.
Discharge Data for Technical Selection
Standard drain, maximum continuous discharge, and pulse-current information offer a more rigorous basis for selection than nominal capacity alone. Compare those values with the device's operating profile and manufacturer limits.
Exact Dimensions and Weight
Published diameter, height, and weight help confirm that the cell will fit a constrained compartment. It is also useful for equipment designers who need to account for battery mass in a portable assembly.

Buying Guide – How to Choose the Best CR123A Batteries
The right CR123A battery depends on device compatibility, expected current draw, storage conditions, and how many spares you need. Capacity and temperature claims are useful, but the device manufacturer's requirements should always take priority.
Confirm the Exact Battery Type
Start with the battery compartment, device manual, or markings on the original cell. CR123A is a common designation, but some manuals also list CR123, CR17345, DL123A, EL123, SF123A, 123A, or another code. Several products in this guide cover multiple designations, but a similar name does not guarantee identical dimensions, discharge behavior, or suitability for high-current devices.
Match Chemistry to the Device
Most products here are disposable 3-volt lithium cells, which are intended for single use. Rechargeable CR123A products often use lithium-ion chemistry and may require a dedicated charger, while some security cameras use a rechargeable pack with a different shape or protection circuit. Treat rechargeable and non-rechargeable options as separate categories unless the manufacturer explicitly approves interchangeability.
Compare Capacity Carefully
Capacity is normally expressed in mAh and indicates how much charge a cell can hold under specified test conditions. The Panasonic and SureFire products list 1,550mAh, while HW states 1,700mAh, but direct runtime comparisons can be misleading when discharge rates, temperatures, and cutoff voltages differ. A larger stated capacity is most useful in equipment that consumes batteries regularly rather than in a device that sits unused for months.
Consider Expected Current Draw
Low-drain sensors and remote controls may place modest demands on a battery, while bright flashlights, professional cameras, and some security devices can require stronger output. For technical applications, review the battery's standard drain, maximum continuous discharge, and pulse ratings. The Panasonic Industrial listing is especially useful here because it provides those figures in addition to nominal capacity.
Evaluate Temperature Demands
Temperature affects lithium-cell performance, and outdoor cameras, vehicle equipment, emergency lights, and field tools may be used well beyond room conditions. Duracell emphasizes a wide range from sub-freezing to high heat, DURNERGY states -40°F to 185°F, HW states -40°F to 158°F, and Panasonic Industrial lists -40°C to +70°C. These ranges are useful differentiators, but they do not excuse poor storage practices or use outside the manufacturer's recommendations.
Look for Long-Term Storage Support
A ten-year storage claim is meaningful for emergency kits, vehicle kits, and sensors that are seldom used. Duracell includes a storage guarantee, Energizer says its photo batteries last up to ten years in storage, and other listings make similar shelf-life claims. Storage life does not mean the battery should remain installed for the entire period; follow the device maker's replacement schedule and keep spare cells in their original packaging.
Choose the Right Pack Quantity
Two-cell packs suit a single device, four- and six-cell packs serve a small household, and twelve-cell packs reduce the need for frequent reordering. Bulk options make sense for high-use flashlights, security equipment, professional kits, or shared emergency supplies. A smaller pack is more economical for occasional use and easier to keep organized. Count the devices you intend to power and add a reasonable reserve rather than buying solely by pack size.
Review Safety and Certification Details
Look for leakage mitigation, PTC protection, and credible certification marks, particularly for batteries kept in high-drain equipment or long-term storage. HW highlights a leak-proof design, PTC protection, and UL and RoHS certification, while DURNERGY lists CE, IEC60086-4, and UL1642. Certification and safety claims should complement proper installation and storage rather than replace them.
How to Use and Care for Your CR123A Batteries
Before installation, confirm that the battery type, voltage, dimensions, and polarity match the device requirements. Remove the old cells, clean the compartment if it is dirty, and install the replacement according to the plus and minus markings. Do not mix new and old batteries, cells from different manufacturers, or rechargeable and disposable batteries unless the device manufacturer explicitly allows it.
Store unused CR123A batteries in their original packaging in a cool, dry place away from direct sunlight, excessive heat, moisture, and conductive materials. Avoid crushing, puncturing, disassembling, or carrying loose loose cells beside keys, coins, and tools. For an emergency kit, use an organized container and mark it clearly so the cells can be rotated and inspected periodically.
Remove a battery that leaks, swells, corrodes, or becomes damaged, and follow local battery-disposal guidance. If a device begins to display a low-battery warning or shows reduced performance, replace the cell promptly. For products that remain installed for long periods, check the manufacturer's recommended replacement interval even if the battery still appears to work.
Frequently Asked Questions
Can I use a CR123A battery instead of CR123 or CR17345?
Sometimes, but only when the device manufacturer confirms compatibility. The batteries may share a common nominal voltage and belong to the same broad 123 family, yet codes can differ in dimensions, capacity, or discharge characteristics. Check the manual, original battery markings, polarity, and physical fit before making a substitution.
Are CR123A batteries rechargeable?
The CR123A batteries in this guide are disposable, non-rechargeable lithium cells. Rechargeable products sold for some camera and security applications are generally lithium-ion packs with their own charger and protection requirements. Never attempt to recharge a disposable cell, and do not substitute a rechargeable pack unless the device documentation specifically approves it.
How long do CR123A batteries last in storage?
Several listings in this guide claim up to ten years of storage or shelf life, depending on the brand and product. Actual retention varies with temperature, humidity, packaging, and cell condition. Keep unused batteries in their original packaging and store them in a moderate, dry environment for the best chance of retaining their intended service life.
Does a higher mAh rating mean my device will run longer?
A higher mAh rating can translate into longer runtime when the cells are otherwise comparable, but it is not the only factor. Current draw, battery age, temperature, device cutoff voltage, and the quality of the connection also affect performance. The Panasonic Industrial discharge data can be especially useful when matching a battery to a demanding device.
Can CR123A batteries be used in security cameras and alarm sensors?
Many CR123A lithium cells are marketed for home-security cameras, alarm sensors, and smart-home devices, but compatibility is device-specific. Some cameras require rechargeable lithium-ion packs, and the Amazon Basics listing specifically says it is not recommended for Arlo security cameras. Confirm the exact battery required by the camera or sensor before purchasing.
What is the difference between CR123A and CR123 battery labels?
Both labels are frequently used for similar compact 3-volt lithium cells, and many manufacturers list them together as compatible designations. However, labels do not provide a complete technical specification. Confirm nominal voltage, diameter, height, and the device maker's recommendation, especially for professional cameras or equipment with unusual current requirements.
Can CR123A batteries be used outdoors or in cold weather?
Several products in this guide advertise broad operating temperature ranges, making them better suited to outdoor equipment than cells with no stated performance information. Cold can temporarily reduce battery output, while excessive heat can accelerate deterioration. Choose a product whose stated range covers the environment and store the batteries properly when they are not in use.
Is it safe to keep spare CR123A batteries in a home emergency kit?
Yes, when they are stored correctly. Keep the cells in their original packaging or a dedicated battery organizer, away from heat, moisture, and conductive objects. Inspect stored batteries periodically, follow replacement dates or manufacturer guidance, and dispose of damaged or leaking cells through an appropriate local battery-recycling program.
Final Thoughts on Choosing the Best CR123A Batteries
The Duracell CR123A six-pack is the strongest all-around recommendation because of its high rating, professional device positioning, ten-year storage guarantee, and wide temperature claims. SureFire is the premium choice for high-drain use and a larger reserve, while the HW pack is a value-focused alternative with a high stated capacity and detailed safety features.
Prioritize exact device compatibility first, followed by chemistry, current draw, operating temperature, and pack quantity. Energizer and Panasonic options are particularly attractive for cameras, flashlights, and smart-home equipment, while the Panasonic Industrial pack is the most useful for buyers who need precise discharge and dimensional data.
Ratings, product details, availability, and prices can change, so review the current listing before buying and confirm the manufacturer's battery specification for your device. That final check helps ensure that the CR123A battery you select not only fits the compartment but also matches the way the equipment is designed to operate.
