CR123 and 18350 batteries differ primarily in size, voltage, capacity, rechargeability, and typical usage. CR123 batteries are non-rechargeable with a nominal voltage of 3V and higher capacity, while 18350 batteries are rechargeable lithium-ion cells with about 3.7V and lower capacity but designed for high-drain applications. Selecting the right battery depends on these key distinctions and device compatibility.
How Do CR123 and 18350 Batteries Differ in Voltage and Capacity?
CR123 batteries typically provide a nominal voltage of 3V and capacities ranging from 1300 to 1700 mAh. In contrast, 18350 batteries have a higher nominal voltage around 3.7V but usually lower capacities, between 800 to 1200 mAh. While the 18350 delivers more voltage per cell, the CR123 offers greater capacity per charge cycle for longer runtime in many devices.
This voltage and capacity difference affects device performance, power output, and runtime, requiring compatibility considerations when choosing between the two.
What Are the Size and Shape Differences Between CR123 and 18350 Batteries?
Physically, CR123 batteries measure approximately 17mm in diameter and 34.5mm in length. The 18350 battery is slightly larger, with an 18mm diameter and 35mm length. Though subtle, these size differences impact their interchangeability in devices designed for specific battery sizes.
When replacing or substituting these batteries, ensuring device fit is crucial to avoid damage or poor electrical contact.
Which Battery Is Rechargeable: CR123 or 18350?
The CR123 battery is generally non-rechargeable, intended for single-use applications. On the other hand, the 18350 is a rechargeable lithium-ion cell designed to endure numerous charging cycles, making it more cost-effective and environmentally friendly over time.

Rechargeability makes the 18350 suitable for devices with frequent power demands, while CR123 suits intermittent, long-term storage needs.
How Do Typical Applications Differ for CR123 and 18350 Batteries?
CR123 batteries are widely used in cameras, security systems, and high-performance flashlights where reliable, long-lasting power is essential without frequent battery changes. The 18350 battery, due to its rechargeable nature and compact size, is popular in high-drain devices like vape pens, compact flashlights, and portable electronics that benefit from repeated use and fast rechargeability.
Understanding device requirements ensures choosing the right battery type for optimal performance.
What Are the Shelf Life and Cost Differences Between CR123 and 18350 Batteries?
CR123 batteries have a longer shelf life, often up to 10 years due to their non-rechargeable lithium chemistry and stable discharge characteristics. In comparison, 18350 rechargeable batteries typically last 3 to 5 years before capacity degrades due to chemical aging processes.
While CR123 cells cost less initially, frequent replacement adds up. The 18350’s higher upfront cost is compensated by rechargeability and cost savings over repeated usage.
Are There Safety Considerations When Using CR123 or 18350 Batteries?
Both battery types require proper handling. CR123 batteries, being non-rechargeable, avoid risks linked to improper charging but must be disposed of safely. Rechargeable 18350 batteries need battery management systems and compatible chargers to avoid overcharging, overheating, or short circuits. Using quality brand batteries like those from Redway Battery ensures adherence to safety standards and reduces risks.
Manufacturers recommend always following device and battery supplier guidelines for storage, charging, and disposal.
When Should You Choose CR123 Over 18350 Batteries or Vice Versa?
Choose CR123 batteries for devices requiring high capacity, infrequent replacement, and stable power output with long shelf life, especially when rechargeability isn’t essential. Opt for 18350 rechargeable batteries in devices needing frequent recharging, compact size, and higher voltage performance, like vaping devices and tactical flashlights.
Compatibility with device specifications also guides the best choice.
