When it comes to portable electronics and devices, batteries play a vital role in providing the necessary power. Two popular options in the market are the 18650 and 14500 batteries. In this comprehensive comparison, we will delve into their size, capacity, voltage, and applications to help you make an informed decision based on your specific needs.
18650 battery is a type of rechargeable lithium-ion battery that is commonly used in electronic devices. The “18650” refers to its dimensions, which are 18mm in diameter and 65mm in length. These batteries are widely used in laptop batteries, flashlights, electric vehicles, and other electronic devices that require high energy density and long-lasting power.
18650 batteries are known for their high energy density, which means they can store a large amount of energy in a small space. They are also known for their long lifespan and durability, making them a popular choice for use in high-performance devices. Additionally, many 18650 batteries are rechargeable, allowing users to save money and reduce waste by reusing them instead of disposing of them after use.
What is 14500 battery?
14500 battery is a type of rechargeable lithium-ion battery that is similar in size to a standard AA battery. The “14500” designation refers to its dimensions, which are 14mm in diameter and 50mm in length. These batteries are commonly used in smaller electronic devices such as flashlights, digital cameras, and other portable electronics.
Like other lithium-ion batteries, 14500 batteries are known for their high energy density and long lifespan. They are also rechargeable, which means they can be used multiple times and are more environmentally friendly than disposable batteries. However, because of their smaller size, 14500 batteries typically have a lower capacity and lower discharge rate than larger lithium-ion batteries such as the 18650 battery.
18650 vs 14500 battery, which is better?
The 18650 and 14500 are both types of lithium-ion rechargeable batteries commonly used in electronic devices. Here is a comparison between the two in terms of their dimensions:
- Size: The 18650 is a larger battery, measuring 18mm in diameter and 65mm in length, while the 14500 measures 14mm in diameter and 50mm in length.
- Capacity: Due to its larger size, the 18650 typically has a higher capacity than the 14500. For example, a typical 18650 battery has a capacity of 2500mAh, while a typical 14500 battery has a capacity of 800mAh.
- Voltage: Both batteries have a nominal voltage of 3.7 volts, but the 18650 is capable of delivering higher currents due to its larger size.
- Applications: The 18650 is commonly used in devices that require higher capacity and longer run times, such as flashlights, laptops, and electric vehicles. The 14500 is commonly used in smaller devices that require less power, such as flashlights, cameras, and remote controls.
Overall, the 18650 is a larger battery that typically has a higher capacity and is capable of delivering higher currents, while the 14500 is a smaller battery that is suitable for applications that require less power.
