I am currently using a Lenovo Z50-70 laptop. My battery condition is very poor and it lasts for only 20mins. So I decided to replace the dead cells inside the laptop battery on my own.
My Laptop battery consists of 4 cells with a Capacity of 2200mAh(14.4V). What I am planning to do is to replace all the 4 cells with a new 18650 cell with a capacity of 2600mAh of each. So my whole capacity will be (2600mAh*4=10400mAh) and each cell rated with 3.7V.
My Question is whether this going to work or not? If yes, what are the factors to be considered while replacing my dead cell with a new one? My implementation crosses the manufactures capacity, so will this going to affect my laptop in any way?
