Super expensive laptop batteries have always bothered me.
If you've ever taken one apart you know whats inside them. A bunch of AA cells strung together in series. Thats it. They're not top of the line Energizer or Duracell either, they are the cheapest of the cheap AA lithium ion cells mass produced in china or japan or where ever is cheapest at the moment. They are worth no more than $5 in total. Its appalling how much these companies charge for trash.
This isn't to say all companies use such shit. There are a few that custom make their own batteries for better performance and size.
