Reply to comment by mapinis in Apple’s New AirPods Are Telling Users to Replace the Batteries Already. Too Bad That’s Impossible by speckz

I'm just spitballing but you could have the battery embedded within a plastic headless bolt, then you screw that bolt into the "arm" of the headphones. Have metal contacts like a lightbulb to connect it to the rest of the headphone.

Have a torx screw head exposed from the outside, now to replace the battery you unscrew this bolt to get the battery out and replace it with another battery in bolt unit.

Interesting idea, but I definitley don't want a screwdriver applying any sort of force to be anywhere near a lithium ion battery. That's how you get explosions.

A lithium ion explosion the size of an airpod? Shall I fetch a tablespoon of sand just in case?

Lol, you just make it so the threads stop before it hits the end, with a flexible connector. Unless you turn so hard you strip it (which, dumb) it's fine!

Then sweat wicks in and you get corrosion or a short, not great with a lithium battery that goes partially in your head

Put locktite or petroleum jelly in there, or a rubber seal. Then it's waterproof. Plus if the positive and negative terminals are far enough apart you'll never get a short between them.

Not against sweat, it’s corrosive and once it’s in there you have to worry about electrolysis. There is a reason it is not done. The battery is as isolated as possible against sweat intrusion because of this.
