Batteries have become an essential part of modern life, powering everything from smartphones and laptops to electric vehicles and power tools. Lithium-ion batteries, in particular, have become the go-to choice for portable electronic devices due to their high energy density, longer lifespan, and fast charging capabilities.
Among the many types of lithium-ion batteries available in the market, the 16340 and 18350 batteries stand out as popular choices. These batteries are widely used in flashlights, vaping devices, and other electronic devices that require a rechargeable, high-performance battery.
However, choosing the right battery can be confusing, especially for those who are new to the world of rechargeable batteries. In this article, we will provide an in-depth comparison of the 16340 and 18350 batteries, exploring their differences in size, capacity, voltage, and other factors that can affect their usage. By the end of this article, you should have a better understanding of which battery is best suited for your device’s needs.
Differences Between 16340 vs 18350 Batteries
The first and most apparent difference between these two batteries is their size. The 16340 battery measures 16mm in diameter and 34mm in length, while the 18350 battery is slightly bigger, with a diameter of 18mm and a length of 35mm. As a result, the 18350 battery is bulkier and may not fit into devices that require a smaller battery.

Capacity refers to the amount of energy stored in a battery. A higher capacity battery will last longer than a lower capacity battery. The capacity of a battery is measured in milliampere-hours (mAh).
In general, 18350 batteries have a higher capacity than 16340 batteries. The 16340 battery typically has a capacity of around 700mAh, while the 18350 battery has a capacity of 900mAh or more. This means that the 18350 battery can last longer than the 16340 battery when used in the same device.
Voltage is the electrical potential difference between two points in a circuit. In batteries, it is the force that drives current through a device. The voltage of a battery is measured in volts (V).
Both 16340 and 18350 batteries have a nominal voltage of 3.7V. However, the actual voltage of a battery can vary depending on its charge level and other factors. Generally, a higher voltage battery will provide more power to the device.
Apart from size, capacity, and voltage, there are a few other factors to consider when choosing between these two batteries.
Firstly, the maximum discharge rate of the battery can affect the device’s performance. The maximum discharge rate is measured in amps (A) and indicates how much current the battery can deliver at once. The 18350 battery usually has a higher maximum discharge rate than the 16340 battery, making it more suitable for high-powered devices.
Secondly, the charging time of the battery can also be an important factor. The charging time varies depending on the charger used and the battery’s capacity. However, in general, the 18350 battery takes longer to charge than the 16340 battery due to its higher capacity.
The choice between the 16340 and 18350 batteries depends on the device’s requirements and usage. If size is a concern, the 16340 battery may be a better option. However, if you need a battery with a higher capacity and discharge rate, the 18350 battery is the way to go. Additionally, it’s important to consider factors such as voltage and charging time when choosing between these two batteries. Ultimately, choosing the right battery can ensure optimal performance and longevity of your electronic devices.
