efficiency and help calibrate the electronics that monitor and maintain the
battery charge.
Over time, as the battery is charged and discharged, it gradually stores less
charge. Li-Ion cells generally last for 500 or more cycles before they begin to
deteriorate. You should replace the battery when you notice that it begins to
store significantly less charge.

disassemble the battery pack.
