I Bought a Mac: Get More Life Out Of Your MacBook Battery

Thanks for the tips.
Looking at iStat tonight, I just noticed that my MacBook Pro's battery health is only at 66%.. Something I was quite surprized to see. I've had the MBP for a year, but my battery was replaced not that long ago in the recall. It's been through a mere 73 cycles, and I cycle my battery more or less once a month. I wasn't planning on buying a new battery for at least another year, but at this point I'm thinking it'll be much sooner than that. Maybe when it hits 40% ish.
BTW: How do you disable Dashboard?

Dashboard: It's not the easiest thing to do from what I can tell, especially since I'm not the terminal guru but here's a link to an article about it: Link

To maximize the performance of your battery,you should "Fully charge/discharge battery up to 4 cycles before achieving full capacity of a new battery " and there are lots of "battery do" and "battery don't", you can see it at : http://www.go-shop.com.au/batterybrands.php/Lap...

Goshop,
Careful there... you are teetering on the edge of comment spam. I do like the tip on the charging though so I'll let it pass through. Thanks for the tip!
Question for you: Does NEC make the MacBook batteries? I guess I have never looked.

With lithium batteries does it really help to cycle them by running them to empty. I thought this went the way of the NI-CADs... Do I have bad info?

I'm not a battery expert, but I think it isn't so much the memory issue any more with lithium batteries, but it's just a good idea to "work them out" a bit so they last longer (lifetime wise).

1) use your out-of-the-box mac until it completely discharges and goes into deep sleep where you can't wake it without plugging in the power cord 2) leave it in deep sleep for 5 hours 3) completely charge 4) completely discharge
As of today, my MacBook and I have been together for 40 days. Yesterday, while I was happily surfing (on battery), it powered down with no warning. Okay, these things happen. I plugged it in, restarted, and all seemed to be fine. Battery was about 70%. I did other things on my other machines and when it was about 90%, unplugged it and everything was good. This morning after using it unplugged for 1.5 hours it did the same thing, but decided to only work with the power adapter, not on battery alone. When trying to boot without AC, it would try to spin the CD and then fall back into off. When on AC, if I pulled the adapter, it would last two seconds and go blank. I made an appt. with the Apple store (Fashion Show Mall, Las Vegas) for 3:20pm. I got there right at 3:20pm and the monitors showed I was 5th in line. Store was fairly packed, at least one patron at every display item. Monitors also said the next MacGenius appt. was "approx. 8:30pm." Glad I made an appt! I was served about 15 min. later, during which time the monitors had changed to "No more MacGenius appts. available today, please try tomorrow." However, one guy came by without an appt. and was told he would be put on standby and to come back in 30 min.
Once I explained my issue with my MacBook battery, my Genius tried one of his batteries. "I just want to make sure it's your battery and not your motherboard." My machine worked fine, so he said "No problem, I'll have you out of here in 10 minutes." He got me a brand new battery, tested it, and put my old one in a box on the rear counter with four others. He pulled the serial number from the "About this Mac" area, didn't need my receipt for purchase date or anything. I had even printed this page: http://www.apple.com/support/macbook_macbookpro... to use as ammunition, but didn't need it. He did approve highly of my dashboard widget "iStat pro", available here: http://islayer.com/.
So the battery issue is a very common problem, and one that Apple has tried to deal with as painlessly as possible for the consumer. My Genius did ask if the battery showed an "X" in the icon bar, and I said no. Just wouldn't run on battery. On the way out of the store, one of the 3 MacBooks, in fact the one closest to the door, had an "X" on the battery icon. When I unplugged the power, it shut down immediately! The moral of the story is to contact Apple immediately with problems and give them a chance to fix them. Hope this helps others.

Another tip you might want to consider is removing the battery when you can easily connect it to the power chord, that way you don't overcharge the battery.

Word of warning.
Don't drop the battery...
I dropped mine yesterday, and it's bent. Kind of like S-shaped.
Thankfully it still fits in, with only one of the edges sticking out a millimeter.
Be safe!

Hi there I have only rarely run my macbook pro from the battery. Lately though, when I do and even though I might have anywhere from 50 to 70% of battery life left, my machine just stops working, shuts down. I've learned finally never to run on anything but electric. I've had the mac about a year and a half. I will have to get a new battery I assume but it seems such a short time for it to wear out,

what is the average stand by time for a mac battery. mine goes for 1.5 hour and 2 hours non functional. Is this OK ? or I need new batteries.

That sounds a little short of what they claim but it does really depend on how many things you have eating up the battery. When running on battery power, the time depends on the amount of resources you are using if that makes sense.

My 15" Macbook pro shuts down when my battery gets to about 77%. The only option then is to run it on the power cord. When operating on the battery alone, the power drops from 97% to 77% in mere minutes. The cycle count for the battery is at 90. Is it safe to assume the battery is crap or should I look for other problems?

An Apple tech told me that my MacBook battery has an expected life of 200 charging cycles; when I checked my cycle count in the about this Mac menu I found I had over 350. I figured it was time for a new one because it just wasn't working. I was also told that the battery needs to be used; leaving the computer plugged in while the battery is fully charged will decrease the life of the battery.

I recommend using low light display by ctrl-alt-cmd-8. It helps the battery life if you only deal with the text and not the images etc (ex. coding on the train or reading a papers etc...)

A few things to note. If you are under warranty or have an APP and are having issues with your battery dying suddenly, like some of you are. Then take it to your Apple repair store and they can run a test to see if it is a dud battery or its just used. If if its a dud then they can replace it if you are covered by warranty. Also with good battery practices for macbooks... if you have your laptop plugged in all the time try to once a week un plug the macbook and let it run on battery and once it gets around 25% plug it back in. This keeps the battery in good condition and will let you get the best battery life out of your macbook... I just checked mine and I have just gone over 450 cycles and my battery health is still 100%. Good luck :)

If your battery health is below 100%, can doing the above tips bring it back up? Or will it always be at a lower health?

I think it's an age thing... If it's a couple years old and your health is below 100% then I don't know if there's a method to get that back up.
