Hi. I replaced my battery just less than a month ago with an ifixit replacement battery and today it suddenly says that its not charging. The computer runs fine (albeit a bit slow) when the mag safe power adapter is plugged in but turns off as soon as it is unplugged. I have tried resetting the SMC and the PRAM with no results. The light on the power adapter is amber and changes to green for a second when I reset the SMC. Reading other questions here it seems like it might be a faulty battery but I just wanted to check before seeking other options. Below is a screen shot of what Coconut battery tells me about it. Does anyone have any ideas? Thanks in advance.
Check your charger is the cord damaged in any way? Make sure the MagSafe connector is also clean and not damaged both the cord end and the socket. Make sure you have real Apple charger not a fake!

As Dan stated above, it could be the charger. Does it charge when the Macbook is powered off? If you’ve checked that, i’d say the battery is at fault.
