Why does my replacement battery not work?

I replaced the A1322 battery in my 13" Macbook Pro (mid 2009) and the battery icon has a black "X" in it. It will not charge and the computer says "no batteries available."

I reinstalled the old battery and it worked fine. What should I do to get the new battery to work?

I have the same problem. Bought a replacement A1322 battery here on ifixit for my macbook pro, early 2011 model. Followed all instructions to install. I still have the same battery indicator I had with the old battery:

The icon shows the battery plugged in, with the words "(Not Charging)"

I took the whole thing apart again, and checked: the connector is as tight as it should be, properly seated. Still no battery charge.

The second answer to this post is definitely for the macs with the easily removable batteries on the bottom of the case; not for the unibodies.

(However, if you've got one of the older MacBooks, try it. It works on my phone when it won't charge!)

I have a unibody MacBook Pro 13" and the battery is not removable as this video describes. I think this fix is for the original MacBookPro (pre 2009) and is not relevant to my problem. Thanks for the tip, though.

If you are attempting to contact iFixit customer service you're in the wrong place (use the link at the bottom of the page). This is the volunteer DIY help forum, we are not employed or affiliated with iFixit in any way.

Double check that connector/connection/cable at both ends. Many times beginner DIYers "think" or "believe' they have correctly reassembled their machines only to find on second look that connectors they "knew" were good were not. Ensure the connector is square and fully snapped into the logic board.

Have to talked to your vendor? Brand new batteries (especially the cheap Chinese knockoffs) have been known to fail straight out of the box.

Also some newer models of MacBooks will not boot without a 15% charge on the battery.

If this answer is acceptable please remember to return and mark it.
