Features:
Standardized Size and Shape
The 18650 lithium - ion battery pack is based on a standardized cylindrical shape. The "18650" indicates that the battery is 18mm in diameter and 65mm in length. This standardization allows for easy integration into a wide range of devices. For example, in battery - powered flashlights, the cylindrical shape of 18650 batteries fits well into the flashlight's tube - like body, enabling a compact and efficient design.
The consistent size also makes it possible to use battery holders and charging devices that are specifically designed for 18650 batteries. Manufacturers can produce products with interchangeable battery compartments, which is convenient for users who may need to replace or upgrade their batteries.
Rechargeability
These battery packs are rechargeable, which is a major advantage over non - rechargeable batteries. They can be recharged hundreds or even thousands of times, depending on the quality of the battery and the charging conditions. This makes them a cost - effective solution in the long run. For example, in a cordless power tool, the ability to recharge the 18650 battery pack means that the user doesn't have to constantly buy new batteries, reducing waste and cost.
The recharge process is usually relatively simple. They can be charged using a dedicated Li - ion battery charger, which typically monitors the charging process to prevent over - charging and over - heating.
Safety Features
Most 18650 Li - ion battery packs come with safety features such as over - charge protection, over - discharge protection, and short - circuit protection. The over - charge protection circuitry prevents the battery from being charged beyond its safe limit, which could lead to damage or even a safety hazard such as over - heating or explosion. Over - discharge protection ensures that the battery is not drained too low, which can affect its lifespan and performance.
Short - circuit protection is also vital. If a short - circuit occurs, the protection mechanism in the battery pack quickly cuts off the current to prevent damage to the battery and the device it powers.
