Let’s dive into the world of 14500 and 18650 batteries and discover which one suits your requirements.

Is 14500 same as 18650?

Are 14500 and 18650 batteries the same? In short, no. While they may seem similar at first glance due to their cylindrical shape, they have distinct differences that make them unique.

14500 and 18650 batteries are not the same. The numbers in their names represent their respective dimensions. While both batteries are cylindrical, the 14500 battery has a diameter of 14mm and a height of 50mm, whereas the 18650 battery has a diameter of 18mm and a height of 65mm. These physical differences result in variations in their capacity, power output, and applications.

One of the main differences is their size – a 14500 battery is smaller than an 18650 battery, with a diameter of only 14mm compared to the latter’s 18mm diameter. This means that while both can be used in certain devices, not all gadgets are compatible with both types of batteries due to size constraints.

Another difference lies in their capacity and voltage output. Generally speaking, an 18650 battery has a higher capacity and voltage output than its counterpart. This makes it suitable for devices that require more power or longer-lasting performance.



These two types of batteries also differ in terms of price point. Due to its larger size and higher performance capabilities, an 18650 battery tends to be more expensive than a 14500 one.

While both these batteries share some similarities due to their cylindrical shape, they are different when it comes down to specifics like size, capacity and price point.

What is the difference?

When it comes to batteries, the numbers and letters can be confusing. 14500 and 18650 are two types of lithium-ion batteries that look similar in size but have some key differences.

The main differences between the 14500 and 18650 batteries lie in their size, capacity, and power output:

  • The 14500 battery is smaller in size compared to the 18650 battery.
  • The 18650 battery has a higher capacity and power output than the 14500 battery.
  • The 14500 battery is commonly used in smaller devices, while the 18650 battery is often found in larger devices.

The first difference is their size. A 14500 battery measures about 14mm by 50mm while an 18650 battery is larger at around18mm by65mm. This means that an18650 has a higher capacity compared to a 14500, which translates into more power for your device.

Another significant difference between these batteries is their voltage output. While both are rated for3.7 volts, the actual voltage may vary depending on usage and other factors.

A third key difference worth noting is their cost. As expected, since an18650 has a higher capacity than a14500,it typically costs more.

Understanding the differences between these two batteries will help you choose the right one for your specific needs based on power requirements and budget constraints.

Can I replace 14500 with 18650?

When it comes to replacing a 14500 battery with an 18650, there are some things you need to consider before doing so.

While the 14500 and 18650 batteries have different sizes and capacities, it may be possible to replace a 14500 battery with an 18650 battery in certain situations. However, it is essential to consider the device’s compatibility and the potential impact on performance and safety. Always refer to the device’s specifications and consult with a battery expert before making any substitutions.

Firstly, the physical size of the batteries is different. While both are cylindrical in shape, the 18650 is larger than the 14500. This means that if your device was designed specifically for a 14500 battery, then using an 18650 could result in compatibility issues due to its larger size.

Moreover, another important factor to consider when replacing batteries is their voltage and capacity rating. The voltage and capacity ratings of these two batteries differ significantly from each other which may affect your device’s performance and lifespan.

It’s worth noting that while some devices can accept either type of battery without any issue but many manufacturers recommend only using specific types for optimal performance.

So before swapping out one battery type for another always consult with your manufacturer or read up on which replacement options work best with your device’s specifications.

Which one should you choose?

When it comes to choosing between a 14500 and an 18650 battery, there are a few factors that you need to consider. Firstly, the size of your device’s battery compartment will play a significant role in determining which one is suitable for you.

Choosing between the 14500 and 18650 batteries depends on your specific requirements:

  • If you have a smaller device that requires a compact battery, the 14500 battery is a suitable choice.
  • For devices that demand higher capacity and power output, the 18650 battery is a better option.
  • Consider the physical constraints of your device and the power needs to make an informed decision.

If your device has a smaller battery compartment, then the 14500 should be your go-to option as it is significantly smaller than the 18650. However, if you have ample space in your device’s battery compartment and require longer run times, then the 18650 may be more appropriate for you.

Another factor to consider when choosing between these two batteries is their capacity. The typical capacity of an 18650 ranges from around 2000mAh to over 3000mAh while that of a 14500 ranges from about half this capacity at best.

So if longevity matters to you and higher-capacity devices are required for usage on-the-go without needing frequent recharge cycles or changing out batteries altogether then opting for an high-capacity option like an 18650 would clearly make sense.

Ultimately, selecting either one depends on how much power output and longevity matter most based upon whatever scenario such as outdoor camping trips where access could be limited or extended periods requiring portable energy sources with strong output levels needed throughout long work days while maintaining steady performance levels regardless conditions encountered along way.

What is a 14500 battery used for?

A 14500 battery is a type of rechargeable lithium-ion battery that has a cylindrical shape and measures approximately 14mm in diameter and 50mm in length. Despite its smaller size compared to the more common 18650 battery, the 14500 can still deliver high levels of power output.

The 14500 battery finds applications in various devices, including:

  • Flashlights
  • Electronic toys
  • Remote controls
  • Portable electronics

Due to its compact size, these batteries are often used in portable electronic devices such as flashlights, vape pens, and digital cameras. They are also commonly found in small DIY projects like LED lights or Arduino boards.

One advantage of using a 14500 battery over other types of batteries is their ability to provide higher voltage while maintaining a relatively low profile. This makes them ideal for use in applications where space is limited.

However, it’s important to note that because they have less capacity than larger batteries like the 18650s, the run time on these devices may be shorter. But if you’re looking for a reliable source of power for your smaller electronics projects or need something with less bulk and weight than an 18650 battery, then the versatile little powerhouse that is the 14500 might just fit your needs perfectly!

What battery can I use instead of 18650?

To sum up, while both 14500 and 18650 batteries are lithium-ion rechargeable batteries, there are distinct differences in terms of size, capacity, and usage. The choice between the two depends on your specific needs, preferences, and device specifications.

If you’re looking for an alternative to the 18650 battery, consider the following options:

  • 14500 battery: Provides a smaller form factor with lower capacity and power output.
  • Lithium-ion battery: Offers comparable capacity and power output with different dimensions.

For devices that require a smaller battery with relatively lower capacity such as flashlights or electronic cigarettes, a 14500 battery might be more suitable. On the other hand, for high-powered devices like laptops or power banks that require higher voltage and longer run time between charges, an 18650 battery is more appropriate.

If you don’t have access to an 18650 battery but need one for your device urgently then you can use other types of batteries as well such as CR123A which has similar specs to the 18650 albeit at a slightly lower capacity. However it is important to note that using an incorrect type of battery can damage your device so always ensure that you check its specification before attempting any replacements.
