First let's get a better idea of what's going on with this battery. A 2014 battery should not be failing.

Download and run Coconut Battery and let us know your results.

Oh, this is very, very strange. Low cycles, high charge percentage, but not charging and condition of the battery listed as poor. Please give us any history of this machine you can. I have not seen anything like this in my 37 years of working with Apple products. Are you using an original AC adapter? Any liquid damage?

의 답변

Yes, very strange to believe.

I normally received 6 to 7 hours backup after one full charge.

I am using original adapter comes with box, no there is no liquid damage.

When the issue starts/noticed,

I shutdown the system from office for cleaning, but one of my client came to see me, so i forgot to clean it. I closed it and left office, when i tied to open from home, its not working. But when i connect MagSafe 2, it start working.

Is that a problem of battery or any board? I am really sad because, i am caring this machine that much.

의 답변

I'm at a loss. Let's see if @danj has an idea. I just don't know.

service engineer fixed issue by replacing battery with new one. Thank you for all the support.

Mayer i have one small query, after replacement how to normalize the battery calculations? As per their suggestion i done 8 hours continuous charging.

But the remaining time is not correct some times.

I went to Apple Store and checked the solution they requested to keep the system under observation. Due to work emergency I did battery replacement from a local repair store costing me nearly $90. (if it is 13'' cost become cheaper)
