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!
What's New
Version 2.7.2:
Added an export to csv option of the saved battery data (for import to Numbers or Excel)
Fixed a bug where coconutBattery did not work correctly on some MacBook Pros
Version 2.7.1 doesn't work as expected on my early 2008 Macbook Pro (Intel) 15 inches. It show battery capacity of -1 mAh, but life of my Mac and model is correct.
Version 2.6.6 work fine. Please fix and make it work with my Macbook pro. I want to use 2.7.1
I cannot find anywhere to write to developer, and that;s why I have to post a comment here
Nice app! I recently replaced the battery in my MacBook because, though it was functioning, the old battery was actually expanding (physically) to the point where it was protruding out the bottom of my laptop. I don't know about these sorts of things, but figured that couldn't be good. I got a new battery, and just checked it with this app. It read "100%", and still correctly calculated the age of my laptop. Impressive! Since I now know the battery can start doing weird things, I will use this app, and thank the developer!
Using CB version 2.7 on a MBP, 2.53 GHz Intel Core 2 Duo, 4 GB RAM, age 19 months. Battery capacity had been slowly declining to 96%.
I check coconutBattery every evening prior to shut down to estimate how best to use the battery the following day, and have also been monitoring capacity at full charge over time, allowing to discharge when capacity starts to drift lower, and at half charge - same thing - watching for a decline or improvement in capacity.
When needed, allowing to discharge fully, set over night then recharge fully.
By also running the battery 20 - 40% during the day, and down to 4% a couple of times, capacity is now back up over 100% to 102% or 6650 mAh capacity against an original designed capacity of 6500 mAh.
Very cool.
Very useful for free software.
I wrote this review in order to do better justice to CoconutBattery v2.7 and improve its rating -3.5 stars- by comparison with Battery Health monitor v -4.5 stars-. In my view the former deserves at least the same rating as the latter !
in fact, well, I avow... I couldn't compare exactly right now the 2 above versions; I could only compare these 2 products on 2 PPC macs (I had no Intel mac available), one iBook G4 with OS 10.4.11 et the other Powerbook G4 with OS 10.5.8; CoconutBattery v2.7 works only on Intel macs; so I could only use respectively:
OS 10.4.11/iBookG4 CoconutBattery v2.6.7 & Battery Health Monitor vv1.5
OS 10.5.8/PowerbookG4alu CoconutBattery v2.6.7 & Battery Health Monitor v1.2 to v1.5
The key issue is that Battery Health Monitor, whaterver the version, cannot read (at all or partly) the battery status data on the PowerbookG4alu as the developer Sonora Graphics acknowledges candidly on its website (recommanding to use older versions such as v1.2, but it didn't work at all in my case)... while CoconutBattery works well in all cases without a glitch !
For the record (yes I know it shouldn't be here ^v^ !), similarily I used the excellent "iStat pro" v4.9.2 widget by http://islayer.com/apps/istatpro/ on both mchines & OS without any problem; iStat pro has, on top of many useful indicators about your machine, has a small section with your battery key figures
(just a very minor issue: below the key battery figures, a bit weird and rather unuseful (?) large white bar which I suppose is some kind of visual indicator (?) I say weird because this bar is topped by the word "Unknown" on the PowerbookG4alu ? and this word becomes "Charged" on the iBookG4 -anyway I can, amongst the figures, read "charge: 100%"-, but this bar may mean something else ?)
Very useful tool for its limited purpose.
Especially the timeline (click on the right-side arrow)
Only improvement I could think of is an automatic timeline.
(btw, my non-Apple battery works as charm and has 101% left of the original capacity)
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.
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).

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!
