Chosen Solution
I followed this guide to replace the battery in my 11-inch, mid-2012 MacBook Air. All seemed to go well at first, but the battery connector has come loose twice now. The first time I opened the case back up and rearranged the cable before plugging it back in. This fix lasted less than 24 hours. Does anyone have any advice for me before I go in and try again?
Common issue for 3rd party or “original” batteries (i.e. original reject or imitation 3rd party batteries), since the battery connector does not stay in as well as the original. A lot of good 3rd party brands glue plastic on top of this, which holds the connector in (since the bottom cover holds it in when screwed in). Do the same, or use foam adhesive to pad the top, which will do the same job
