18650 Li-ion 2000mAh Rechargeable Battery

Description

1. Voltage: An 18650 Li-ion battery typically has a nominal voltage of 3.7 volts. When fully charged, it can have a voltage of around 4.2 volts, and when nearly depleted, it can drop to about 3.0 volts.
2. Capacity: The “2000mAh” rating indicates the battery’s capacity, which stands for 2000 milliampere-hours. This rating represents the amount of charge the battery can store and deliver. In this case, the battery can provide a continuous current of 2000mA (or 2 amperes) for one hour before reaching its cutoff voltage.
3. Chemistry: 18650 batteries typically use lithium-ion (Li-ion) chemistry, known for its high energy density and rechargeable properties.
4. Size: The “18650” label refers to the battery’s dimensions. An 18650 battery is approximately 18mm in diameter and 65mm in length. However, there can be slight variations in size between manufacturers and models.
5. Rechargeable: Li-ion 18650 batteries are rechargeable and can be recharged hundreds of times before their capacity significantly degrades.
6. Applications: These batteries are used in a wide range of applications, including laptops, cordless power tools, e-cigarettes, LED flashlights, and other portable electronic devices. They are also popular in the DIY electronics and electric vehicle (EV) communities.
