Li-polymer Cell Factory Wholesale Bluetooth Earphone Battery UFX903090 3.7V 3000mAh Rechargeable Battery

Description Review

Description

The 903090 lithium-ion battery is a type of rechargeable battery that has a rectangular shape and measures 90mm in length, 30mm in width, and 9mm in height. It is commonly used in a wide range of electronic devices, such as smartphones, tablets, GPS devices, and digital cameras.

Lithium-ion batteries are known for their high energy density, long lifespan, and low self-discharge rate. They use lithium ions to move back and forth between the positive and negative electrodes during charge and discharge cycles. This results in a flow of electrons, which can be harnessed to power electronic devices.
