First ThinkPad Li-Ion Battery | What is inside? 

In this Video I take a look in an early ThinkPad Li-Ion Battery. This kind of Batteries where produced from the Mid 90´s. The first use oft this battery was, as far as I know, in the ThinkPad 755CD. This form of battery was used up to the ThinkPad 765. The ThinkPad 770 used a different battery pack.
