My Mid 2012 doesn't have any plastic on the battery connector. Near to impossible to remove it.

Worked flawlessly on my MBA. Installed in 5 minutes. Coconut Battery now reports 6801 mAh on a design capacity of 6700 mah. That's an improvement as my old battery was clocking a meager 61% of design capacity (i.e., 4087) after 371 cycles.

Easy. Perfect replacement.

I tried to opened it and I failed. The screw doesn't work well. Worst idea ever!

Very easy. I bought the "A-Stock" battery. It came at a max charge of 6300mAh (max of 6700) -- decent. But within 2 weeks dropped down to a max of around 4,000 mAh. I'm thinking that I should have spent the extra $10 and bought the new battery. (I am using the Coconut Battery App.)

Update -- after about a month with the A-Stock battery, I got the "Service Battery" warning, but it did not stay -- disappeared after a while. Strange behavior. I would not recommend buying anything but a new battery based on this experience.

Guide was perfect. Saw several other guides mention T5 screws for back cover. This guide was correct with the 5-point Pentalobes. Got the iFixIt 54-bit driver set. Worked perfectly. Bit disappointed that CoconutBattery reports the battery is capable of 98% charge (6583/6700mAh) but I can live with that vs. the 48% on old battery. Thanks for the guide and parts.

The guide was great, the supplied screwdrivers worked, everything was where it was supposed to be (e.g. the plastic handle on the battery connector) - I was done in 10 minutes. Everything as advertised.

My batter was new, 6812 mAh.

Straightforward guide, completed in about 20 mins. The new battery reports 6746 mAh. Many thanks.
