Air 2011 battery issues

[lhoffstadt]

Hi, I want to ask some advice please regarding my laptop. I replaced the battery on my MacBook Air because the previous one was not holding a good charge. After I put the new battery the percentage on the battery information is acting weird. The laptop power off having still 15%. After I plug in the power adapter it show me 1% so the OS is not reading the correct information.

Any recommendation on how to fix this?

Thank you.

Have you tried to reset SMC?

Hi, thanks for your answer. I have not tried yet to reset it. Will it affect the OS if I do that? Thank you

Smc and nvram reset will not affect the os.

Have you tried calibrating the battery? Where did you get the battery?

There is been latest reports that third parties batteries may not work for Macbooks, unconfirmed.

Ifixit has a blip on that, batt sold by ifixit, they are advising return for refund if it doesn't work.

That was my case I bought the battery on ifixit, I will return it and get it someplace else. Probably that is the issue.

Thank you all for the help and advice.

I have (had) some issues (not charging, inaccurate % showing, mac won't turn on if power cord is not plugged in and others,) with a replacement to my original battery on my MB Air mid 2011. The battery was third party (BRTong) purchased a year ago last month from Amazon (39 bucks).

I started to have issues about 6 months on using it. I tried SMC and PRAM resets and had the same issues. Then I tried to reset (took out the cable and placed it back in) inside the mac. After that, it works again. Currently it's showing health is 100%, condition is normal, and already have 64 charging cycles.

So FYI.
