    • If you're installing a new battery, you should calibrate it after installation:

    • Charge it to 100%, and then keep charging it for at least 2 more hours. Next, unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.

    • If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook's SMC.

Hi!

After I changed the battery my Mac says "Check battery". Should I be worried?

leffe149 - Responder

as the label said, "Warning, do not remove the battery", is that any risks if I disobey it?

To remove the batteri the guide say to use a 13 mm Tri-wing for one of the screws. That cant pissibly be right

Monika - Responder

Actually Monika, the guide says that a Tri-wing is needed for two of the screws, which it is. My new battery came with a tool for that but I'd already discovered that it's easy to remove these two screws with a fine straight (non-Philip's head) driver.

Thanks Phillip Takahashi (and your five co-authors). That was a straight forward and clear guide.

Hello

I changed the battery and it keeps telling me that there is replacement needed

Also the indicator said the battery is 150% charged.

Is that normal and how do i remove the status that said the battery isn't ok and change it in to an ok status?

Please help
