Wyze watch battery

Is the battery a lithium ion battery. The postal service will not ship my watch from my friend in the US to Canada if it is. Oddly wyze shipped it to a US address.

Thanks for any help or suggestions


Welcome to the Wyze community @southlancaster!
I believe the both Wyze watches use lithium ion batteries, most smart watches do.
The postal service may not want to ship the lithium ion battery to another country. Wyze also uses FedEx most of the time, so they may have different policies the USPS or other shipping services.
