Installed new A1309 Battery and does not power up by it

I purchased this battery a while ago and lost it. I found it again and decided to try to install as the laptop runs mainly on power cord. After installing the laptop would not start unless plugged into the power cord. It say that no battery is installed and is running on the cord.

Did I purchase the wrong battery? What else could be of issue?

Do you get a orange light on the charger? If yes let it charge for a while as the battery may be dead quite and take a long time to charge from 0%.

If we get results from coconutBattery that look like this image, the battery is a dud. Replacing it with a new one should do the trick.
