PineTime brand new, battery dead

[rcl69100]

I just received my PineTime Pine64 yesterday.

Upon arrival, the battery was at 0%, 3.10V.
I charged it yesterday, and the battery indicator went from 0% to 18% after 50 minutes, then to 54% and stuck.

Today, it dropped back to 0% this morning and won’t charge.
What are my options to get a working watch?
Thank you.

I figure out to start the watch, but the battery stay at 54%, and go to 0% after few minutes only.

I think I need a battery replacement for the Watch.

I searched how I can order one, I did not found any online store.
Anyone can help me ?
