I changed my Macbook Air's battery one month ago. It is a mid 2011, 11". I've changed it for a cheap battery bought on Amazon : http://www.ansanorapple.com/ansanorr-high-quality-new-laptop-battery-for-apple-apple-macbook-air-11-a1406-a1495-a1465-p-8.html

It worked fine for one week, then the battery started disconnecting on a regular basis from motherboard. The little connector from the battery to the board "jumps" pretty often from its place. I then can use the Mac only if plugged in (the battery icon has a little cross on it + message "no battery available"). Until I reopen it, and reconnect the battery. Pretty annoying.

I wonder if it is more likely that :

1/ Shocks do that. Not very likely to me as I tried pulling on the connector with my finger to see if this can happen.

2/ Some "ejection system" kicks my battery out. As if the system detected overheating or such thing and decided to eject the battery.

3/ Any other reason ?
