The problem is that there is plenty of stuff that you probably don't even realize has a Lithium Ion battery in it. With a phone at least it's obvious. But what about that controller for your e-bike? Camera? Remote control? Headphones? Authentication token? Toy? Microscope? and so on... they're everywhere. And they are not always announced properly, especially smaller pouch cells.

https://www.phonak.com/en-us/hearing-devices/hearing-aids/ly... I find this egregious: "Lyric requires no maintenance or batteries to change or charge." and again "No batteries or charging needed."

But you have two tiny potential bombs inserted into your head.

> Better yet, Lyric requires no maintenance or batteries to change or charge.

> The battery is specifically designed to withstand the deep ear environment for months at a time

Have Phonak/Lyric achieved the impossible building a battery that never runs out of power? How does that work?

Looks like rather than replacing or recharging the battery, you have the entire thing removed and a new one placed.

If it doesn't get charged then I doubt it has a lithium ion battery. But i can't find any specific information.
