Generally speaking I like to change the battery once the battery is completely used up, but the system will kept notifying me once the percentage dropped below 20%. Is there a way to turn it off (or make the notification only comes up once it dropped below 5%)?

  • would this work for you apple.stackexchange.com/a/57427/46541 – Ruskes Apr 9 '15 at 2:26
  • @Buscar웃 no it doesn't turn off the alerts. It just replaces the icons. – aeroxy Apr 10 '15 at 4:18
  • That alert is probably there for the Lion batteries which should not be discharged below 20%. I do not know how to turn it off. – Ruskes Apr 10 '15 at 4:57

    It is a very annoying alert... My batteries still work for weeks past the 20% mark. Here's hoping Apple will allow us to disable it in the near future. – djule5 Jul 8 '15 at 21:12

I don't mind the alert or warning, but I do mind the weeks of having a blinking icon in my Menubar. Here's what I did in Terminal:

$ cd /System/Library/CoreServices/Menu\ Extras/Bluetooth.menu/Contents/Resources/
$ sudo cp lowbatt.pdf lowbatt.backup.pdf
$ sudo cp BlueTooth_Connected.pdf lowbatt.pdf

This replaces the low battery icon with the same connected icon. I assume the icon is still "blinking" in that it's switching one for the other, but since they're now the same, you don't notice.

Now I get the 20%, 10%, 5% alerts, but no annoying blink.

This is in Lion. It's likely that system updates and perhaps even Mountain Lion will undo this, but it can probably be reapplied after updates are performed.

For Mountain Lion, the relevant files are named:

  • Bluetooth_Low_Battery.pdf
  • Bluetooth_Connected.pdf
