Everybody know Li-ion batteries. They are the ones that we usually get on our phones, tablets, laptops and almost everything. (Actually, the only products I remember nowadays continue using old Ni-Mh/Ni-Cd batteries are cordless phones and some cordless drills).
According to the info you can find, lithium batteries have to be treated in a totally different way from old batteries. For example, it isn't bad plug them in whenever you want, and is really bad wait to load them when they are completely empty. However, in reality, it's amazingly incredible how this and the 90% of the practices that you shouldn't do are false.
Lithium batteries perform much much better if you use them as old Ni-Mh batteries.
So, we can say that the performance of the lithium batteries, like the Newton's laws, is something that can only be demonstrated in practice.
