DESCRIPTION
coconutBattery is a tool that reads out the data of your notebook-battery (iBook/Powerbook). It gives you live feedback, what's going on in your battery (not only a snapshot like other tools).

It shows the current charge of your battery as well as the current maximum capacity related to its original. If coconutBattery detects that you have connected the wrong charger (i.e. an ibook-charger plugged in a powerbook) it will warn you! That's a cool feature!

Of course you are able to save the current maximum capacity of your battery - with just one click! coconutBattery uses Apple's new and really powerful technology named "CoreData" to realize that.

Finally coconutBattery calculates the age of your Mac exactly! So you can derive the age of your battery. And last but not least: coconutBattery is Universal Binary (you can run it on Intel-Macs! - cool!) and it is complete localizable!

DORKYPANTS  Wow! …almost instantaneous results on my Snow Leopard MBP. By comparison 2.6.5 took several seconds from launch until it was able to display results. FYI, System Profiler (from About This Mac, then More Info…) can also show a lot of the battery charge information under Hardware>Power, though coconutBattery does it faster and presents the data more informatively. And it's free.

AYUB  Works fine for me. But the widget version says Loadcycles: 7 (wrong) whereas the app shows Loadcycles: 279 (correct,matched with iStat Pro widget version).

MAUDLIN  I have a 2.16 Ghz MacBook and coconutBattery 2.6.5 shows Current Battery Capacity 5148mAh - greater than its Original Battery Capacity of 5020 mAh. This is from a 19 month old machine which has gone through 136 Battery Load Cycles. I'm using OS 10.5.6.

I've tried several previous versions which have all also shown current capacity at more than 100% original capacity.

GREGM  PPC G4 PowerBook, OS 10.5.6

Looks just fine. Info matches actual performance of the battery. Spot on for age, etc.

MacOS X 10.4.5+ is the **ONLY** requirement showing on the developers web page.

AKROBAT  Great app. Does what it says and works fine.

I think Macsintx & Person1229 should notice that a Macbook or Macbook Pro is part of the requirement for this app, which is why it displays wrongly on their iBook G4.

EASER  Then the description on MacUpdate should be changed, since it currenty says "coconutBattery is a tool that reads out the data of your notebook-battery (iBook/Powerbook)." Seems to pretty blatantly say "iBook."

MACSINTX  On my iBook G4, the values reported seem to be reported in the wrong fields.

-Current Battery Charge is 15392 mAh.

-Maximum Battery Charge is 2504 mAh.

These values are completely wrong. How could Maximum be less than Current.

-Current Battery Capacity is 2504 mAh.

-Original Battery Capacity is 299 mAh.

These values are completely wrong. How could Original be less than Current.

PERSON1229  Mmm... I don't think it's working on my iBook G4 (late 2005) computer running Leopard.

IVANOVITCH  That's better: the previous version didn't match battery cycles with Apple's System Profiler - now it does.

GARYI  My battery is 10 months, it shows my current capacity as higher than the original capacity.

Which was nice.
