As with every manufactured good, certain things are prioritized. Your small commodity laptop battery was likely made to be cheap and light, but not necessarily built to last a long time.

That's like comparing a lawn mower engine and an engine in a car designed to last hundreds of thousands of kilometers. They just weren't designed with the same things in mind.

Tesla especially has done a fantastic job with the chemistry and cooling allowing their batteries to have long life even when they are rapidly charged (which usually wrecks batteries).
