Product Description
3.7V 21700 battery High Capacity Rechagable Lithium Ion Battery
4800mAh
Features
1. Voltage: The 3.7V 21700 battery has a nominal voltage of 3.7
volts, which is standard for lithium-ion batteries. This voltage is
commonly used in a wide range of electronic devices and
applications.
2. Capacity: The 4800mAh capacity of the 3.7V 21700 battery
indicates the amount of charge it can store. With a higher
capacity, it can provide longer runtime between charges, making it
suitable for devices that require high energy demands or extended
operating times.
3. Rechargeable: The 3.7V 21700 battery is rechargeable, allowing
it to be used repeatedly by charging and discharging cycles. This
makes it a cost-effective and environmentally friendly power
solution compared to single-use disposable batteries.
4. High Capacity: With a capacity of 4800mAh, the 3.7V 21700
battery offers a significant amount of energy storage. It is
suitable for powering devices and applications that require higher
power consumption, such as high-drain devices, portable
electronics, electric vehicles, power tools, and other consumer and
industrial applications.
5. Lithium-Ion Technology: The 3.7V 21700 battery utilizes
lithium-ion (Li-ion) chemistry, known for its high energy density,
lightweight design, and excellent cycle life. Li-ion batteries
provide stable and reliable power, making them widely used in
various electronic devices.
6. Form Factor: The 21700 designation refers to the battery's
dimensions. It has a diameter of approximately 21mm and a length of
approximately 70mm. The 21700 form factor is larger than the
commonly used 18650 batteries and offers higher capacity due to the
increased size.
