Check Your Mac's Battery Health In System Profiler

We know that laptop batteries don't last forever, but sometimes it's hard to tell whether your battery is actually dying or whether you're just imagining bad battery life. Here's how to keep up with your MacBook battery's health without extra software.

Reader haxorknight explains that your battery's health information is readily available from System Profiler:

If you own a MacBook, you can open the System Profiler by hitting More Info in "About this Mac." Go down to the "Power" section and you can keep track of the battery's health and cycle count.

I think for the Macbook Pros the cycle where the battery is supposed to lose its longevity is about 800.

In the screenshot above, the battery health is listed as normal and the number of cycles is only in the 200s, so we can assume this is a healthy battery. If it weren't, it will say something like "Check Battery" instead of "Normal".

While many pieces of software (like previously mentioned iStat Menus) do a good job of keeping track of this, it's nice to know that the same information is hidden away in your Mac somewhere, especially if you don't want to install extra software.


    This a great article! very handy for people to know. You can also hold down the OPTION key and click on your battery status on the top of your menu bar on the right, this will tell you the condition of your battery =)

    That's funny. My macbook says "check battery" and tells me I should get it serviced, but using the method you describe, it claims I only have 280 cycles. So I don't know which to believe.

    My condition says 'good' is this better than normal? different to normal? It's had 981 cycles. I guess I'll just take good as a good thing for now.
