I got my battery replaced with a battery that I bought from iFixit and it charged to 91% but wont charge anymore. It says “Battery Not Charging. Power Source: Power Adapter”. Any ideas on what might be the issue or what I should do? Thanks.
Check if it will run from battery. Which year of the MacBook it is? Also do an SMC and PRAM reset. See this and this pagehow to do it. Also try running the battery to the 0% until the MacBook sleeps and then charge it again. If anything else fails, try reinstalling the old battery if perhaps is still somewhat useable and see if it will charge it completely.
