18650 Cylindrical Battery 2000mAh Lithium Ion Battery For Home Appliances
The most common type of lithium battery is the li-ion battery. This technology has a number of advantages over other battery technologies:
Li-ion battery have a high energy density, which means they can store a lot of energy in a small space.
They have a high power density, which means the li-ion battery can provide a lot of power (current) for a short period of time.
They have a low self-discharge rate, which means they lose very little of their charge when not in use.
The li-ion battery are lightweight and compact, which makes them ideal for portable electronic devices.
