My Macbook Pro 13" (mid '09) battery does not charge, even with a new battery

Hi all,

 

My Macbook Pro 13" (mid '09) battery does not charge, even with a new battery. It says 'Status: replace now'. I tried to reset SMC (using ctrl+alt+shift+power), but nothing helps.

 

Edit: I also replaced the MagSafe adapter, but still nothing..

 

Does anybody know what I could try to do?
