Lithium ion batteries have a sweet spot of around 60 to 80 percent charge where very little wear takes place to charge or discharge. If you could keep it to just that 20-30 percent usage in that range it would pretty much last ten thousand cycles.

Charging to 100 or discharging below 50-60 percent accelerates the wear on the battery, but it is still much better than the wear rate on lead acid batteries that are cycled in a similar manner.

I’m sure we did a cycle of network booting thin clients and windows terminal services about 10 or 15 years ago. 🤔

But what’s the point of having your newly-purchased $3000 wooden volume knob and polyatomic copper ring bus lift yet another veil from the soundstage if you’re blindfolded?
