Understanding 21700 and 26650 Batteries: 

In the world of rechargeable batteries, the 21700 and 26650 models are becoming increasingly popular due to their high capacity and efficiency. These batteries are commonly used in electric vehicles, power tools, and various electronic devices. In this article, we will delve into the specifics of 21700 and 26650 batteries, comparing their features, applications, and benefits to help you understand which might be the best choice for your needs.

What Are 21700 and 26650 Batteries?

21700 Batteries:

The 21700 battery is a lithium-ion cell that measures 21mm in diameter and 70mm in length. Developed by companies like Tesla and Panasonic, the 21700 battery offers a higher energy density compared to older models like the 18650. This increase in size allows for more capacity and longer run times, making it ideal for high-drain applications.

26650 Batteries:

The 26650 battery is another lithium-ion cell, but it measures 26mm in diameter and 65mm in length. These batteries are known for their robust capacity and are often used in high-performance flashlights, vaping devices, and portable power banks. The 26650 battery offers a significant amount of power and can maintain a stable output over longer periods.

Key Features and Specifications:


One of the primary differences between the 21700 and 26650 batteries is their capacity. The 21700 battery typically has a capacity ranging from 3000mAh to 5000mAh, while the 26650 battery usually ranges from 4000mAh to 6000mAh. This means that 26650 batteries generally provide more power and longer usage times before needing to be recharged.

Energy Density:

Energy density refers to the amount of energy a battery can store relative to its size. The 21700 battery has a higher energy density compared to the 26650, which means it can store more energy in a smaller space. This makes the 21700 battery an excellent choice for applications where space is limited but high power is needed.


Weight is another factor to consider when choosing between these two batteries. The 21700 battery is lighter than the 26650, making it preferable for portable devices where weight is a concern. However, the 26650’s slightly heavier weight is often justified by its higher capacity and longer run times.

Applications of 21700 and 26650 Batteries:

Electric Vehicles:

The 21700 battery is widely used in electric vehicles (EVs) due to its high energy density and efficiency. Tesla, for instance, has adopted the 21700 cells for their newer models, enabling longer driving ranges and better performance.

Power Tools:

Both 21700 and 26650 batteries are popular in power tools. The choice between the two often depends on the specific requirements of the tool. For instance, a tool that requires a lightweight battery with high power might use a 21700 battery, while a tool needing longer operation times might opt for a 26650 battery.

Flashlights and Vaping Devices:

The 26650 battery is a favorite in high-performance flashlights and vaping devices. Its high capacity ensures that these devices can operate for extended periods without frequent battery recharges. The stable output of the 26650 battery also ensures consistent performance.

Portable Power Banks:

Both types of batteries are used in portable power banks, with the choice depending on the desired balance between size, weight, and capacity. The 21700 battery’s higher energy density makes it suitable for compact power banks, while the 26650’s larger capacity is beneficial for power banks designed to charge multiple devices or provide power over extended periods.

Everything You Need to Know About ICR 18650 Batteries:

In today’s world, batteries are essential for powering a wide range of devices, from smartphones to electric vehicles. Among the various types of batteries, the ICR 18650 battery stands out for its efficiency, reliability, and versatility. This article will delve into the details of ICR 18650 batteries, exploring their composition, uses, advantages, and safety considerations.

What is an ICR 18650 Battery?

The term “ICR” in ICR 18650 batteries stands for “Lithium Cobalt Rechargeable.” The “18650” refers to the battery’s dimensions: 18mm in diameter and 65mm in length. These batteries are a type of lithium-ion battery, known for their high energy density and long-lasting power. They are commonly used in various applications, including laptops, flashlights, and power tools, due to their ability to deliver a substantial amount of energy in a compact form.
