Batteries have become much cheaper, making energy storage far more affordable.

Having had a mono radio cassette player in my bedroom in 1976, running off D-cells, that was not my experience.

The biggest drain was the volume, not the cassette player. You noticed it getting slower and slower, but the drain came from playing it loud.

My Sony Walkman a few years later ran forever on its batteries.
