I have two questions:

  1. Is the battery for MacBook Pro 13" Unibody Mid 2009 still in stock? I need one for my macbook.
  2. My macbook’s speaker jars a lot, is there a sub woofer in this model??

Hi djapoorv, Yes! and Yes! 1.) iFixit sells the battery you need. You can find it here. 2.) There is a subwoofer in this model. Many users have experienced audio distortion and shaking from the right speaker/ subwoofer when they turn the volume about 50%, so you aren’t the only one. If the shaking continues to bother you, check out this guide to replace or repair the subwoofer and right speaker. You can also find the replacement part on iFixit, just follow this link.
