Advanced lithium-ion materials allow us to back efficient power sources that last a long time and work for many different kinds of things. In order to choose the correct battery for your device, it is vital to understand the different 3.7 volt battery sizes and their specs.
Overview of 3.7 Volt Battery Sizes
3.7 volt batteries are widely used in portable electronics, power tools, and electric vehicles. Among these, cylindrical lithium-ion batteries are prevalent, with various standard sizes such as 21700, 26650, and 18650. The numbers correspond to the battery’s dimensions—in millimeters—where the first two digits represent the diameter and the remaining digits the length. For example, the 18650 battery 2200mAh measures approximately 18mm in diameter and 65mm in length. The 18650 size is popular due to its balance of capacity, voltage, and compatibility with many devices.
Key Features of the 18650 3.7v 2200mAh Lithium Ion Battery
The 18650 3.7v 2200mAh lithium ion battery stands out for its reliable capacity and voltage output. With a nominal voltage of 3.7 volts and a capacity of 2200mAh, it provides a stable and consistent power source suitable for numerous applications. This battery is rechargeable and designed to integrate seamlessly into devices that accommodate the universal 18650 size standard. Additionally, it incorporates advanced lithium-ion chemistry that promotes longer cycle life and environmental sustainability. Its built-in safety mechanisms protect against overcharge, over-discharge, and short-circuit conditions, ensuring reliable operation.
Choosing the Right 3.7 Volt Battery Size for Your Application
Selecting the proper battery size depends on the device requirements, including power consumption, physical space, and expected runtime. While the 18650 battery 2200mAh is widely compatible with many devices, larger cells such as the 21700 provide higher capacity but require more space. It is important to verify the device’s voltage and size specifications before purchasing a battery to ensure optimal performance and safety.
