Issues with batteries

I apologize if this specific question has been answered already.I just got my cameras yesterday. I installed the battery and it was in use for a few hours yesterday. I charged the other one that came with them, but now it is not reading the batteries at all, even charged. It is currently stuck at 13% battery, which is what it was when i took the original battery out cause it needed changed. I have tried everything I can think of. Switching both batteries, and, uninstalling and reinstalling the app. I am really at a loss on what to do.
