SAMSUNG J2 SAMSUNG battery 2600mAh LI-ION OEM

This original Samsung battery offers a 2600 mAh capacity in the J2 format and weighs just 42 g. It is a lithium-ion cell that stores energy in chemical form and releases it as electrical power when needed, making it suitable for mobile devices that rely on a rechargeable power source.

Lithium-ion batteries are among the most widely used types in modern electronics. They combine high energy density, a light weight and a long service life. Unlike older battery technologies, they do not suffer from the so-called memory effect, so their capacity does not noticeably decline through repeated charging.

The 2600 mAh capacity determines how long the device can run between two charges. Service life depends on the number of charge and discharge cycles, the quality of the cell and how it is cared for in everyday use.
