Laptop battery chargers seem much more intelligent.
Mine switches off when the battery is full,
as I can see from the computer,
which seems to have considerable knowledge of the battery -
what its original maximum charge is,
what is the maximum charge it has recently had, etc.
(Incidentally, I can put batteries holding different charges
in my laptop - a Sony Picturebook.)

It's more likely the battery pack which is "intelligent" with a charge
monitoring chip that can be interrogated by the laptop.

Yes, thanks, that seems very plausible.
Especially when one considers the cost of the laptop batteries!
