Battery warning labels for Nintendo Switch and other devices with integrated battery

[hisnoodlyservant]

Hi there,

So been researching if and what kind of battery warning label I need for a Nintendo Switch. I am shipping it via USPS priority. Random Reddit and other forum posts say don't worry about it but have seen others saying the opposite.

I also have a old cell phone and some other random electronics as well I am getting rid of. All of them are lithium ion and integrated.

Reading through the UPS and FedEx battery rules seem pretty confusing.

Anyway, appreciate it.

Don't know how to edit my post but after reading through the rules makes it sounds like I need one. Yet, checked my Newegg laptop box and they didn't have to put one on there.
