The 18650 cylindrical battery is a common rechargeable battery that is widely used in a variety of electronic devices. It has many key characteristics, including capacity, safety, cycle life, discharge performance and size. In this article, we will focus on the five key features of the 18650 cylindrical battery.

01, capacity

The 18650 cylindrical battery typically has a higher capacity and can provide a durable power supply. This makes them ideal for devices that need to be used for a long time, such as laptops, radios, and power tools. In general, 18650 battery capacity can range from 2000 (mAh) to 3500 (mAh).

02, Security

The 18650 battery generally has a high safety performance. They usually adopt multi-layer protection design, including overcharge protection, overdischarge protection, overcurrent protection and short circuit protection. These protective measures can effectively prevent the battery from overcharging and discharging, overcurrent and short circuit, thereby reducing the safety risk of the battery.

03, cycle life

The 18650 battery has a long cycle life and can carry out multiple charge and discharge cycles. This means they can be reused without the need for frequent battery changes. In general, 18650 batteries can have a cycle life of several hundred times or more, making them an affordable and environmentally friendly choice.

04, discharge performance

18650 batteries usually have high discharge performance and can provide a stable current output. This makes them ideal for high-power devices such as electric vehicles, drones, and hand-held tools. The discharge performance of the 18650 battery depends on its internal chemical composition and design, so it needs to be evaluated according to specific needs when choosing a battery.

05. Size

The size of the 18650 battery is relatively small, about 18 mm in diameter and 65 mm in length, hence the name. This compact size makes the 18650 battery ideal for use in devices that need to save space, such as handheld electronics and portable power supplies.

In summary, the 18650 cylindrical lithium battery becomes the ideal choice for many electronic devices, but also needs to pay attention to safe use during use and maintenance to avoid potential risks caused by improper operation.
