I know have a collection of odd power supplies. Could I cost effectively recycle them in a UPS power supply for my Pi or my disks?
Given that you just destroyed the laptop by "experimenting", I would suggest careful consideration before doing anything with batteries, especially if they are lithiums which can explode, actually any battery can explode. Have you considered how you are going to recharge the battery now that the laptop is destroyed? The charge circuit should be inside the laptop.
Of course if it turns out that the battery is made from standard cells of some sort, it might be possible to remove them and reuse them. But you should be careful about all this, I know this sounds paranoid, but I don't want to hear about some sort of fire, good grief.
