Test How Degraded Is Your Apple Laptop's Battery
submitted by mikeazorin 9 days ago (via http://www.coconut-flavour.com...)
Coconut Battery is a Mac OS X application that finds out your original battery capacity and it's current battery capacity. Good way to find out when it's time to get a new battery. My battery? 1165mAh, lasts for less than an hour. :-)

Look for the number after capacity... in a normal battery it should be around 4000-5000.
Mine is at 177, which is why it dies after 4 minutes of use. I carry my power adapter around at all times. ;-)
The terminal tells me 3735 which aint too bad but could be better.
Great program, really useful. The 12" AlBook I picked up on eBay is at 82%, giving me 4 hours, if I am really careful with power management.
Brandenpro, you right. Dang that's a wonderful rape of English. Check this out for a really funny blog by one of the creators of Megatokyo: http://megatokyo.com. Scroll down and read the one under Dom.
The thing lasts 6.5 hours if you leave the screen at low brightness, 5 hours at full and with WiFi and Bluetooth.
I want it! I take comfort with my better video card.
Then I realize she has a DVD burner.
this app is cool, but it would be a lot cooler if Apple spent as much time working on the battery life of that Pbooks and Macbooks as they do on their Ipod.
4022 on a 3year old ti-book... out of 4200 :D
instead of: "Test How Degraded Is Your Apple Laptop's Battery"
should be: "Test How Degraded Your Apple Laptop's Battery IS"
How much are new batteries for TiBooks?
-Digg
Would this (old) method still work?

Current Capacity: 3981 mAh
And I've had my powerbook for 1 year.
But then I don't use the battery all that much. Maybe once or twice have I used it strictly on battery power.
I just tried it and it actually reduced my capacity by 1%! TBH, I don't think it makes any difference.
I just replaced my old battery with a new one from NuPower that I got from macsales.com. I bought the 65 Watt-Hour and I get around 4 to 4 1/2 hours of life out of it. It's amazing little battery compared to my old one. The only thing I don't like, and this is being really picky being that you never see it, is that the metal test button is a metallic sticker on the NuPower.
Riiiggghhhttt.. 5+ hours is completely unacceptable for a laptop battery... that's about the best anyone gets for battery life, dell, sony, or apple... just cause the title says apple doesn't mean you have to start ignorant flame wars, without actually seeing if you're right...
Most non-Mac laptops don't have the sensors to check the available mAh.
quick... name a windows command line string to get your battery life! that's right, there is none... this program is just a gui interface to a unix command built into OS X... it's not possible to develop this exact app for windows, as there is no CLI equivalent command... you fail, refer to my above post: just cause it says apple doesn't mean that you can start a flame, especially when you have no fucking clue what the program really is
my 18month old powerbook is still 4138mAh, 94% of the original.
very impressed :-)
nice little app
4174mAh out of 4400mAh originally. 94%, not bad. 259 cycles.
Too bad my girlfriend has her iBook at school. I wonder what that one is at...
"Degradedness of Your Apple Laptop Battery How? Tested."
Duh.
Both were 4400 mAh when new, so I assume we both own G4 iBooks.
His battery is 26 months old, mine is 27.
His battery has done 170 loadcycles, mine's done 362.
His is at 29% of it's original capacity, mine's at 69%.
And as to the comment about "most non-mac laptops can't do this" - that's bs
It's in the ACPI. For example, my thinkpad will do this w/ the thinkpad ACPI extension
no big deal - mac users need to get over themselves, damn
Or for Windows, for that matter?
Anyone got a windows version of this?
To all the people asking/demanding a Windows or Linux version:
Most non-Mac laptops don't have the sensors to check the available mAh.
"designing programs for macs are all good and well, but if i were a designer, I would make windows versions too, that way your stuff can reach more than 6% of the people"

pc app?.
It's probably true that PC's don't have the necessary sensors to give you this information. Windows, however, does monitor your battery (although it doesn't do so in a very refined fashion). If you want to monitor your battery on a Windows PC in a more precise fashion, try BatteryMon (http://www.passmark.com/products/batmon.htm). It doesn't idiot-proof the process by telling you what your battery SHOULD be capable of, but it does monitor your battery usage in realtime, so if you can do a little math it'll tell you pretty much what you need to know.

yes it does. was your battery originally charged? (the answer is no)
I should get banned for quoting his profanity directed at me? idiot...
no, unfortunately once the Li Ion battery get's a certain amount of charge cycles it will decline in capacity, and it's irreversible... the Li-Ion battery in my phone used to go a week without charging... after two years it would barely last a day... that's just how Li-ion batteries go...
