Replaced battery, magsafe light not on, battery not charging

Replaced the battery after the old one was seeming to expand.

When I first turned on the computer after the battery intallation the battery showed 100%, then it instantly went down to 25% which it has been ever since. The mag-safe light is not turning on and “Battery not Charging” on battery info. I am uploading the coconut battery report if that helps. Thank you for your help!

Thank you very much for your reply, I was just going to update that I moved the charger to another plug and it started charging, but now has gone up to 39% and although at the time the menu stated that the battery was charging now again it is stuck at 39% stating that the battery is not charging… could it be a charger issue?

I am attaching the new coconut Battery report.
