I never imagined that a laptop batery would be like that inside. I tought it was a massive only cell, but it turns out that i was wrong and its a collection of individual cells. I'm quite curious of you will able to revive them because if so that will proof that the industry prefers for us to buy them when they stop working instead of finding a way where we could give them to recycle and the would pay you us a part of the costs of a new one. Also be careful because batteries are toxic and shouldn't be disposed on normal garbage.
