Question: New battery, bad health

Hello, I just replaced a battery in my MacBook Air mid2012. It was Ok (0 cycles, 99% health), but after first charge it shows 0 cycles and only 88% health. Is this normal? Thank you

MacBook Air, macOS High Sierra (10.13.4)

Answer:

No. This is not normal.

Was the battery replaced by Apple. If so, please contact Apple.

1. Reset SMC. Choose the method for “If the battery is non-removable”.

Does this help?


2. Hold the option key down and click  menu in the menu bar.

Choose “System Information” from the dropdown

Hardware > Power > Battery Information >Health Information > Condition

Does it say Condition: Normal?
