Replaced Battery From Ifixit Did Not Last For 2 Months Macbook Air 13 Early 2014

Chosen Solution

I ordered a new battery from ifixit on 02/13. I used it to replace my 6-year old battery. I just noticed that the new battery condition on my mac showed: replace now. I have not use it for 2 months, why does this happen ? Update (04/12/2020)

Please see the image. It shows the battery is in perfect condition, but the system showed battery condition: replace now. Could you please show me how to fix this problem ? Update (04/12/2020)
