Battery Lights on MPB !?!

[amitdoc2b]

Hi.

I noticed there are like 5 battery lights on the macbook pro. If the battery has 3 out of 5 lights light up, does that mean there is 60% battery life left before next charge, or is there only 60% battery life left on the entire battery before its completely dead and can no longer charge again?

Thanks!

How much charge is left before you run out of power. Not the health of the battery itself.

They are on all Apple notebooks and tell you how much battery is left before you will need to charge again.

It's the current charge on the battery. So 3 lights means 60% left, but you an charge it to get back to 5 lights.

The lights on the battery are an indication - to know the exact percentage, have a look on the taskbar.

Those batteries are intelligent enough (read: have a controller on-board) to not fall below the "point of no return"

It shows charge status.

All lights = full charge

The life of the battery can sort of be determined by looking at
system profiler and look under Power, but there are many factors, including cycle count.

If you plug in your laptop all the time without using on battery, the battery will actually degrade. You need to use it on battery, fully discharge and charge, once in awhile.
