I installed my new fixit battery about 10 days ago and went through the calibration procedure. It worked great until yesterday. Now the battery icon shows the battery at 100%, but the power adapter LED is always amber, and the computer shuts off immediately if the power adapter is removed. In other words, the computer will only run when plugged into ac power.
As i know battery has fault. Try to use the old one if it gives you little bit of backup. It confirms that the fault is in the battery or someting else.
