Batteries not lasting long is considered a limitation of our current battery technology. This limitation doesn’t currently exist for typical clothes dryers.
There’s no reason to introduce a new limitation unless the technology makes up for it in other ways. Having to replace a clothes dryer every two years would require the technology to be very good to justify such a burdensome task.
"Having to replace a clothes dryer every two years would require the technology to be very good to justify such a burdensome task."
Or, a cost cutting measure of replacing a long-lasting ball bearing assembly with a shaft rotating in a vinyl cup which wears down to metal-on-metal like mine did after 3 years. Which is the sort of accelerated deprecation the OP was alluding to. Granted, the battery metaphor isn't great as energy storage tech is far from mature.
