That would be the nickel family (NiMH and its predecessors). Laptops changed long ago (I'd venture somewhere in the 90-ies) to Li-whatever. Those have other weak spots: overcharging shortens their lives, especially being overcharged *and* higher temps. More overcharging leads to fireworks. They *need* some electronics to take care of that. Deep discharge is also fatal to their lifetimes.
