Chosen Solution

I just replaced the battery on my Macbook Air 13" mid 2011, one I ordered from iFixIt and the computer recognizes it, but it says cycle count: 0 and condition: replace now. I decided to replace the battery because it only got to 121 cycles before it stopped holding a charge at all and I could only use the laptop when plugged into the power adapter. The battery status says “Not Charging” and the adapter status light does not glow when connected (it does function normally when plugged into any other computer, so the adapter is not the issue). The second it becomes disconnected the computer shuts down. Charge Information: Charge Remaining (mAh): 2545 Fully Charged: No Charging: No Full Charge Capacity (mAh): 6620 Health Information: Cycle Count: 0 Condition: Replace Now Battery Installed: Yes Amperage (mA): 0 Voltage (mV): 7575 I’m at a total loss for what to do next to solve this problem. Could it be the I/O board or cable? Any ideas? Thanks!

If it came into my shop, I would replace the I/O board. Here’s how to do it: MacBook Air 13" Mid 2011 I/O Board Replacement

I would like to add to this discussion. I have ordered 2 batteries from iFixit for a Mid2011 MacBook air and both are looking great with coconut battery….however :

  1. Both are showing “Replace Now” in OSX
  2. Both do not supply power to the system. When the power adapter is disconnected, the MacBook dies.
  3. I have reset the SMC and PRAM.
  4. I have tested both batteries in two different MacBook Air Mid2011’s I have in stock which are in perfect shape and function normally.
  5. Using other batteries I have in stock for these models, all batteries work normally. It’s only the new ones supplied by iFixit that act this way (Show “Replace Now” in the OSX battery status and also will not supply power when the power adapter is disconnected)
  6. Again, this happened with both MacBook Air’s Mid-2011 I have here that are in perfect working condition. I know this is an old thread. But I wanted to interject there might be something else going on besides a faulty IO board or Logic Board issue. There seems to be a compatibility issue with these batteries marked as compatible with this model.

@neven Sounds good. I assume you have also reset the PRAM during your troubleshooting? Sorry it didn’t work for you. Yes…it’s quite frustrating. The other option is using a different supplier for your battery completely or going for a used battery from iFixit to see if that gets you by. Good luck and if you get it sorted out please drop a note on this thread.

Unfortunately, even though this is a four year old thread now, and I hate posting in it, but, it seems to still be happening, and I cannot get the system to run from the battery no matter how much I reset the SMC from the OS or even when powered off. I’m guessing the bad iFixit battery issue has reared its ugly head at the end of 2019. Are there any other ways to attempt to correct the battery condition, or do I just need to try and get a new replacement battery? Its a late 2011 macbook pro. And yes, I even reset the PRAM attempting to fix this. I did get it to not recognize the battery entirely once, but then it just went back to not running from the battery like before after another SMC reset.

I replaced my MacBook Air battery after the battery wouldn’t charge. It worked fine for a few days and now the new battery won’t charge. I am not sure what to do. 2013 model

Can you please help me I installed the battery into my macbook pro 2014 a few months ago and everything was fine and now it’s only operating at 50% capacity and i’m getting less than 4 hours life on it. I have tried a battery calibration, a SMC and a PRAM reset and i still get a “service recommended” warning on the battery Can you help me please?
