On an issue like this you always want to make sure of a couple things. First if the battery is shown in system profiler. Inside system profiler look at the full charge capacity. If the capacity is 0 then you have a bad battery and the case is closed. If not make sure you try resetting the SMC on the unit and see if that changes anything. 

An alternative way to make sure it is not the adapter try to run the MacBook off the adapter without the battery in. If it runs then chances are you have a good adapter.

Best Regards,
