Very few people replace their car battery. Like very few people replace their car engine. It happens, preferably under warranty, but it's not really something you consider when you buy a car.

If the battery degradation makes the car unfit to your needs, it's a bit weird because it would mean you were on the limit, but anyway it's more economic to sell the car as it is and buy another car. Someone will enjoy the old battery.

There is a big difference between replacing a car engine vs replacing a car battery. The hardest part is lifting the heavy battery out and putting the new one in. With a gas engine, there is belts, timing, oil, and lots of other things I am not even aware of.

Almost all of those things -- all you mention, and most of the "lots of other things" -- are within (or firmly attached on the outside of) the engine itself, and are swapped out as integral parts with the engine.
