I had a barely used first generation iPhone in my safe and went to get it the other day to show it to some friends just to discovered it had blown up. It didn't look charred as your modem but it definitely exploded. Next day I ordered a few fire retardant boxes where I put all of my lithium batteries and power banks.

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.
