Q: macbook recognises but will not charge new battery

I was advised to buy a new charger last week and have just been advised by an apple employee to buy a new battery for my MacBook 2009 and i am having the same issue as my old battery.

 

The Mac reconognises the battery but will not charge or run off the battery.

 

Just spent £150 in total on new charger and battery but still having the same problem as before.

 

I have downloaded the firmware update but my Mac is already running the latest software.

 

Regards

 

Jack

MacBook, OS X Mountain Lion (10.8.2)
