Batter life on Macbook Pro

[Nerdy Keith]

When I upgraded to Mountain Lion it changed the battery status on the top of the screen. It used to tell me how many hours of batter I have and now it doesn't, it gives me a percentage. How do I get it to give me an amount of hours of power?

This has already been discussed in several threads:

RMBP Battery %?
Battery Status
Battery - Show Time no longer available​

From the CHECKING STATUS AND HEALTH section of the following link:

On the MBPr and on Mountain Lion, the Menu Bar battery indicator no longer offers "Time Remaining" as an option on the Menu Bar. It still appears in the dropdown menu.

This app can display time remaining on the menu bar: SlimBatteryMonitor

From the BATTERY LIFE FROM A CHARGE section of the following link:

• Your "time remaining" indication is an ever-changing estimate, based on the current workload of your system. It will fluctuate up and down from minute to minute as your power demands change. It is not perfectly accurate, but only an estimate.

The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

That feature was removed in Mountain Lion. You can get it back with the free app Battery Time Remaining.
