Number of Cells
The number of cells is important since the more cells contained in the battery the higher the capacity will be. To determine the number of cells in your laptop battery you need to have some general idea of what cells are being used in your battery. The most common battery cell is the 18650 and is manufactured by LG, Sony, Sanyo, Samsung, Panasonic and many others. The 18650 is a 3.6V cylindrical Li-Ion cell. 18650 has no memory effect (distinguish between digital memory effect) and longer storage life than NiMH battery cells. 18650 is light weight and has a high energy density. It is in effect perfect for building ASUS U52F Battery for laptop and other portable power devices.
