A lithium battery needs a charging pattern that reduces voltage as it gets closer to full. And overcharging a lithium battery gets real spicy real quick. You also don’t want to charge them too fast because spicy.

Nicad and nimh batteries (I erroneously said alkaline above) don’t, you just blast it with a steady voltage until it’s done, with some nuance for nimh that’s not worth diving into here.
