    Hey Everyone!

    My Early 2011 MacBook Pro's battery swelled and needed replacing. I contacted Apple and they said due to it being a legacy product it is no longer supported so I couldn't buy a new battery through them. I purchased a new battery A1322 through Amazon. I have received the new battery. Since installing, the battery will charge, the button on the left side shows full lights, full charge. When I unplug the laptop from power it will instantly die. Yet, if it I plug it back in the battery says its fully charged charged.

    However, OS X is stating to replace the newly inserted battery and Coconut Battery is saying battery failure. So I am just wondering if for sure the battery is a dud or could there be something faulty with my computer that caused the Apple one to swell in the first place?

    Would appreciate any help,

    Thanks!

    It's an older machine so I wouldn't worry about anything causing swelling other than age.

    Battery itself is difficult, it's the likely cause of the problem and first thing to check. Is it a genuine one? There's a lot of fakes or shoddy one's around. I believe they should cost about $80, how much did you pay or do you have a link to where you brought it from?

    If it all checks out you could probably do with a PWM/SMC reset, you can google how to do them if you don't know.

    PRAM / SMC reset may fix it. Otherwise you probably have a defective replacement battery
