I received the batter for my late 2010 in good order. The instructions were easy to follow and the replacement went well. The two tools mentioned are a must - the P5 pentalobe and T5 torx.
My disappointment is that the battery from iFixit is, in fact, not new. No, it has not been used and shows 6700 mAh design capacity. However, Coconut Battery reports the manufacture date of the battery as 12-14-2011 or 1134 days. Also, I am getting 4-6 hours when I expected 5-7. What is the shelf life of an unused battery?
Perhaps iFixit may wish to change the battery description from "Brand New" to "Never Used" and put the manufacture date.
Thanks
Great post and thanks for this tips.

Just arrived the battery.
Replaced in 5 minutes.
Perfect!
My Mac is up, running and charging the new battery.
Thank you

Sounds like you did not follow the conditioning procedure?
My battery arrived today and I was able to install it in about 30 minutes (I have not done this before). My Mac is up and running and the battery has charged up and is in use.
Thanks for all the help.

I followed this instructions. Everything is fine except that I cannot fully insert the pull tab back into the battery connector. How hard do you have to push ? Does it have to make a click ?
Hello Julien,
It will not click, but it will need about the same amount of force to push it in as the amount needed to pull it out. This being said, you should check the battery connector for any debris, and look at all the pins to make sure nothing is broken. Let us know if you succeed!

All went smoothly! A little bit more explanantion about re-inserting the power connector would have been nice. . . . . . .
Saved my 2011 MacAir.
thanks!!!
If you don’t already have these tiny screwdrivers, you might want to also buy the P-5 Pentalobe screwdriver and the little plastic tool (“Spudger”) from IFIXIT. My local hardware store did not have the P-5, so it was a good thing I had ordered it. And the little plastic spudger was helpful in pushing the new battery connector plug into the jack on the board. Getting the T-5 Torx, too, could be handy just to avoid a trip to the hardware store. The price on IFIXIT was not significantly more than I paid at the local Ace hardware.
The instructions you have given to calibrate the new battery are different from the ones that came with it. How do I proceed?
I have found the answer. There are 2 different procedures, one is called CONDITIONING and the other is CALIBRATING. Conditioning of a brand new battery involves one cycle of 12 h uninterrupted charging followed by complete drainage of the battery until MacBook shuts down (repeat this 3 times). Calibrating can be done afterwards on old batteries and involves the usual instructions given by many websites (here, Lifewire, Apple, etc).
Hi John,
If the plastic film is an easily removable layer, you can remove it. If it is glued onto the battery, do not remove the layer.
how important is it to keep the plastic film on the battery? i didn’t see the message at the beginning and removed it :(
if it is important, i would include that message to the step where the new battery is installed.
Good point! I will add a note in the last step. The battery may come installed with a liner and/or thin plastic film. The plastic film is easily removable and should be removed before installation. The liner helps with installation and acts as a layer of defense against punctures.
