A desktop stays in one location. Does not contain a UPS.
A laptop is mobile - can be used in (and powered by) a car. Contains a UPS. Can be used temporarily without power during unexpected events.
Or you can say money is no object and just keep buying batteries.
Technology is still slowly addressing this problem. Part of the solution is sold by Intel with the trade name Atom. HP and others are/were testing better battery technologies (500 cycles) in customer machines (who do not even know they were using experimental batteries). Things will get better because the computer industry is so innovative. And because some American battery companies have decided to let innovators innovate. But currently, laptops are not intended to be used regularly only from batteries.
Laptops are mobile devices that even contain a UPS. Do you regularly operate a desktop only from its UPS battery? Then learn how quickly that UPS battery fails. A UPS for desktops is a cheapest design. Wears out its batteries even faster. Laptops also have a UPS – typically rated only for 300 discharge cycles.
