Pine Phone Battery Issue

[Gribouille]

I bought a compatible battery from eBay for about $6 with free shipping and it works fine. You want a Samsung EB-BJ700BBC battery for a Galaxy J7.

Thank you @Zebulon Walton 

This is a precious information !

You're welcome! The only issue I ran into is that battery had a plastic molding glued to the bottom edge (opposite edge from the contacts) that had to be removed for it to fit in the phone.

My problem is solved with your help    Thank you !

First, I've bought a charger and plug the PinePhone's battery on it for some hours : the battery is alive and the PinePhone was able to boot 
The charger is a 'nx' model 'CEL9012' bought in the same store.

I've bought the battery in my local store : https://www.1001piles.com/searchengine/result/?q=EB-BJ700BBC 

The price is higher than Ebay, but it's a easier and simple for me, and no bad surprise

But, it wasn't the bottom part of the battery to remove, it was the upper part as shown on the pictures.
