Then use a lithium iron phosphate battery. Imagine a classroom full of laptops connected to the mains, that's a big mess. Then again, if going for wires anyway, it's a pity power over ethernet isn't widely deployed, or only one wire would be needed.

Well it doesn't really matter in a classroom if you have a battery or not. You have to have a power supply. If you had a 8 hour battery life and used it every single day in day out then it will not be a 8 hour battery for very long.

Depends on the battery system used. Lithium based batteries don't care about how often they're recharged (if it isn't too extreme, like all the time of every hour), and will lose capacity over time, depending on their charge level and temperature.

Every laptop sold in the last half dozen years or so (or even more) have used lithium batteries and all of them wear out in a fairly predictable rate. So unless you want the to have the combined joy of forcing the school/tax payers/students to buy brand new batteries every year AND having people's laptops run out of juice half way through a school day and having zero ability to recharge them... they ya having computers in a classroom definitely means that your going to have to have a way to actually provide them with electricity. And that means wires to the desks. It's not even a question worth considering.. Unless you like the mental image of classrooms of people mysteriously grouped within 3 feet of every wall outlet and students carrying around powerstrips with their books in their backpacks.

Probably because the wiring was done properly and not ad hoc as will happen with laptops all over the place (all with their own kind of power adaptor). Even easier if the desktops are below the desk.
