Batteries have become an essential part of modern life, powering a wide range of devices, from electronic gadgets to industrial machinery. The widespread adoption of battery-powered devices has resulted in the development of various battery sizes and types, each with unique features and advantages. Two of the most popular battery sizes are the 18350 and 18650 batteries, which are commonly used in electronic devices, including flashlights, vape mods, and other small electronics. Understanding the differences between these two batteries is crucial in selecting the appropriate battery size for your device, based on your needs and preferences. In this article, we will delve deeper into the features of these batteries, including size and weight, capacity, voltage, and charging and discharging characteristics, to help you make an informed decision when selecting a battery for your device.
Differences Between 18350 and 18650 Batteries
Size and Weight
The 18350 battery is smaller in size than the 18650 battery. It has a diameter of 18mm and a length of 35mm, while the 18650 battery has a diameter of 18mm and a length of 65mm. This size difference makes the 18350 battery a more compact option for devices that require a smaller battery.
The 18350 battery is also lighter than the 18650 battery. It typically weighs around 25-30 grams, while the 18650 battery weighs around 45-50 grams. The weight difference is due to the larger capacity of the 18650 battery.

Capacity and Voltage
The capacity of a battery is the amount of energy it can store. The 18650 battery has a larger capacity than the 18350 battery, which means it can provide more power and last longer before needing to be recharged. The 18650 battery typically has a capacity of around 2500-3000mAh, while the 18350 battery has a capacity of around 700-1200mAh.
The voltage of a battery determines the amount of power it can supply. Both the 18350 and 18650 batteries have a nominal voltage of 3.7 volts, but the 18650 battery can provide a higher voltage under load due to its larger capacity. This higher voltage can be important for devices that require a lot of power, such as high-powered flashlights or vape mods.
Charging and Discharging
Both the 18350 and 18650 batteries can be recharged using a lithium-ion battery charger. However, the 18650 battery takes longer to charge due to its larger capacity. It typically takes around 4-6 hours to fully charge an 18650 battery, while an 18350 battery can be charged in 2-4 hours.
When it comes to discharging, the 18650 battery can handle a higher current draw than the 18350 battery due to its larger capacity. This means it can provide more power for longer periods of time without overheating or causing damage to the battery.
Conclusion
The 18350 and 18650 batteries are both popular lithium-ion batteries that are commonly used in electronic devices. The 18350 battery is smaller and lighter, making it a good option for compact devices, while the 18650 battery has a larger capacity and can provide more power for longer periods of time. Ultimately, the choice between the two batteries depends on the specific needs of the device and the user’s preferences.
