Dell 40 WHR 4-Cell Primary Lithium-Ion Battery

so today we are back at my workbench with my dell inspiron two-in-one model 7569 laptop i'm doing yet another video on how to change the battery the last video i did on this i changed battery because it was down to like an hour battery life and about a year and a half later it's back to that same point again where normal web browsing and stuff only lasts about an hour so time for a new battery but why am i making another video when i just made a video about a year ago about this well this time i'm doing a little different instead of replacing it with the same stock three cell battery i am going to try to install this larger four cell battery well how is that gonna fit inside the laptop you say want to blow things up cause fires who knows what kind of havoc will ensue well i think this model was actually designed to take either type of battery if you search online you will not find anyth
