Apple Macbook Battery Help

There are a few tips I have when it comes to keeping track of your battery health and performance. You can do these things from inside your Macbook, or by using a great little application I discovered.

On the battery itself, there is a tiny little ‘button’, for lack of a better word. If you push this, a guage will light up, telling you how much charge is left in the battery. This works whether the battery is installed in the machine, or taken out of it like I have here.

Inside your Macbook, you can go up to the left hand corner, and click the Apple logo. Choose the “About this Mac”, and head to the System Profiler. Once there, click on the “Power” section. You’ll see all the battery information listed to the right. You can find out about:

  • Charge information
  • Charge remaining
  • Full charge capacity
  • Battery health
  • Voltage
  • Amperage
  • Exact model information in case a replacement is ever needed

There’s also a program available called coconutBattery. coconutBattery isn’t just a tool which shows you only the current charge of your battery – it also shows you the current maximum capacity of it in relation to the original capacity your battery had as it left the factory.
You also get information about the battery-loadcycles (how often did you fully load your battery), the current charger (coconutBattery even warns you if you plugged in a wrong charger for your Notebook) and last but not least information about the age of your Mac. Best of all, you can save the current state of your battery, and then track its performance over time. Oh… and did I mention this program is absolutely free?

  2. Another great video as usual. You may also try istat pro it is another good dashboard utility that monitors your macbook’s stats. istat monitors cpu usage, memory usage, battery, uptime – load, computer temps (just about every temp in the computer), processes, fan speeds, hard drive space, and network info.

  3. Nifty, it has nothing on the Ubuntu battery monitor though, it records the status automatically and can make a nice graph out of it, it also tells you if you have a recalled battery.

    Not saying its better than the Mac one, but the nix one is free.

  5. Do you have any problems with heat from the macbook? because the ones i’ve seen in person were not even warm at all but the reviews i’ve read said they get really hot sometimes.

  6. If you don’t have Apple Care but purchased your laptop within the last two years, read this article about free replacements: apple.com/support/macbook_macbookpro/batteryupdate/

    I spent 40 minutes (mostly on hold, the rest arguing because they were very reluctant and passed me around a lot) and on top of it I got a negative reply in the end.

    The page in question was wrong they said. “sorry, we see how you could expect a replacement, but we have a list of serial numbers and yours is not on there…”
    I am so disappointed.

    My next mac will be bought from a 3rd party with a decent warranty. I thought apple cared about customer satisfaction and the high quality of their products but they just don’t want anything to do with you after the sale is made.

    For all you apple employees that can’t (you probably can) believe this, the support case number was 100536246.
