When it comes to selecting batteries for your devices, it’s important to understand the differences between various types of rechargeable batteries. Two commonly used batteries are the 18350 and 18650, which are both part of the lithium-ion battery family. However, they are not interchangeable, and using one in place of the other can lead to performance issues or even damage your device. In this article, we will explore whether you can use an 18350 rechargeable battery in place of a 18650 battery.
Understanding the Difference Between 18350 and 18650 Batteries
Before we dive into whether these batteries can be swapped, let’s first look at the key differences between the two:
- Size and Form Factor:
- The 18350 battery has a diameter of 18mm and a length of 35mm.
- The 18650 battery, on the other hand, has a diameter of 18mm but a length of 65mm.
The difference in length means that the 18650 is significantly longer than the 18350, making it unsuitable for use in devices designed for the shorter 18350.
- Capacity and Power:
- The 18650 battery typically has a higher capacity, ranging from 2500mAh to 3500mAh, or even higher in some cases.
- The 18350, being smaller, has a lower capacity, typically ranging from 700mAh to 1200mAh.
This means that while the 18650 can deliver more power over a longer period, the 18350 will need to be charged more frequently.
- Current Discharge Rating:
- The 18650 generally offers a higher continuous discharge rate (in amps), allowing it to support devices that require more power, such as high-drain devices.
- The 18350 is designed for devices with lower power demands and therefore has a lower discharge rate.
Can You Use an 18350 in Place of an 18650?
The simple answer is no, you should not use an 18350 rechargeable battery in place of a 18650 battery. Here’s why:
- Size Compatibility: The 18650 battery is physically longer, and most devices that use 18650 batteries are designed with specific compartments to hold them securely. An 18350 battery will not fit into a device that requires an 18650, leaving the battery loose and unable to make proper contact with the device’s terminals.
- Reduced Power Output: The 18350 battery’s lower capacity and discharge rate will not be able to provide the necessary power that an 18650 battery can. Using an 18350 in a device designed for an 18650 battery may result in shorter runtime, poorer performance, or potential malfunction of the device.
- Safety Concerns: Using an underpowered battery like the 18350 in a high-drain device could also cause overheating, battery damage, or even hazardous situations. Always use the manufacturer-recommended battery type to ensure the safety of both the device and yourself.
When Can You Use an 18350 Battery?
An 18350 rechargeable battery is suitable for smaller devices with lower power requirements. These can include:
- Flashlights
- Vaping devices
- Small electronics
However, make sure the battery is designed specifically for your device, and always follow the manufacturer’s instructions for battery size and specifications.
Conclusion
In conclusion, while both the 18350 and 18650 are lithium-ion rechargeable batteries, they are not interchangeable. The 18650 battery is larger, has a higher capacity, and is designed for devices that require more power. Using an 18350 in place of an 18650 can lead to compatibility, performance, and safety issues. Always ensure that you use the correct battery type for your device to avoid potential problems and ensure optimal performance.
