MacBook Pro :: 98 Percent Battery Capacity (Not Calibrated)
Apr 15, 2010Why would a battery one day out of the box only be capable of charging to 6808mAH / 6900mAH? Could it just be a matter of the battery not being calibrated yet?

MacBook Pro :: 101 Percent Battery Capacity?
Nov 16, 2010So I just opened Coconut battery, and it is saying that I have 101% battery capacity. How is that even possible? In the other hand, iStat says 100%.

May 7, 2010I've had my Macbook Pro for just over 2 years and recently bought one of the 2010 models. I'm about to sell my old one but when I downloaded Coconut Battery, I saw that my battery holds a lot less charge than it did when it was new: Have I been doing something wrong or is it just low because the laptop is 2 years old? If it's something I've been doing, I don't want to make the same mistake with my new one.

Aug 20, 2010I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
View 4 Replies View RelatedMacBook Pro :: Keeping Battery Charged And Calibrated To Maintain Health
Dec 1, 2009Ever since owning the uMBP, I have kept the battery charged and monthly calibrate it to maintain a 100% battery health. But through this, the laptop limits its portability and it is sometimes extremely tedious to find a plug in order to use it. My question is: Is it really worth it to keep a good battery that will last overtime, or would you prefer simply purchasing a new battery when your old one dies? Also, how big of a difference does a healthy battery compare to a battery put through regular use?

Feb 21, 2008My ibook G4 (running leopard) has a battery that seems to drop from around 75% to the computer shutting down completely (ncluding loss of prefered wifi network) in literally the blink of an eye, with no warning. I have calibrated it. I tried running coconut battery to see its vitals and the program tells me crazy things like it can charge to 12666mAh which we all know is impossible. Any ideas at all? The apple info says it has around 206 cycles on it total. Do I need to just cough up and buy a new battery? I'm hoping not as I just got the computer used through the marketplace and the guy before said he was getting 2-3 hours still.

MacBook Pro :: Battery Dies Around 50 Percent?
Oct 10, 2010The battery on my MBP (2007 2.33 Core 2 Duo) has started to die, just like the three others that came before it. It seems like it's only been a year or so since I got a new battery. Yesterday, I was using it unplugged and the computer shut off when the battery was around 58%. I have never seen a battery shut off that early. The worst I had seen before that was a previous battery that would die around 35%.
A couple questions:
1. Is there something I am doing that is causing my batteries to keep dying so quickly? An Apple Genius told me that keeping the computer plugged in all the time can burn out the battery. I don't really want to bother putting the computer through unnecessary charge cycles to keep up the battery life.
2. Is there any way to recoup some of the lost battery life of my current battery, or is it just dead?
3. In replacing the battery, should I buy another Apple battery from the website, or are there better quality 3rd party MBP batteries?
4. On a side bar, I am thinking about purchasing a new MBP, but I am worried that the battery will have the same problem, and it will be much more of a hassle to fix because everything is internal now. I hate having to hand my computer over to Apple Care for a whole day and be without it.
MacBook Pro :: Battery Health Only 89 Percent
Nov 3, 2010So I bought a macbook pro 13" about a month ago. I've been running coconut battery tests on it and the battery health is only at 89%. This is super upsetting to me. I went to the apple store and they ran their diagnostic test only to tell me that my battery is within specification, so they wouldn't replace it. The health they calculated was 91%.
What should I do? This seems unfair to me.

MacBook Pro :: Not Charge New Battery Until It Went Down To 2 Percent
Jun 20, 2012I bought a new battery for my sisters new used MacBook Pro. The instructions with the new battery was not to charge the new battery until it's was down to 2%. And, how many hours should she expect the battery to last until it needs to be charged? This is with normal web surfing with some streaming.

View 2 Replies View RelatedMacBook Pro :: Laptop Shut Off When Battery Gets Down (5 To 10 Percent)
Nov 23, 2010I'm having a strange issue with my MBP 1, 1. It's recently picked up a new habit that I find to be rather annoying. When the battery gets down to between 5 and 10%, the laptop will just shut off. No hibernation, no sleep, just a hard shutoff. The battery seems to be in good health; although it does have a high cycle count, I still get around 2 hours of usage out of a charge. I would think that a calibration would solve the problem, but with the hard shutdown, would that even be possible?
View 2 Replies View RelatedOS X :: MacBook Pro Battery Charge Status At 97 Percent
Dec 22, 2010So when I bought this the guy said that Apple installed a new battery on it recently. I believe him because when I downloaded the iStat Pro widget it said only 2 or 3 cycles which is because I calibrated the battery. But I just finished charging and the light is green. But it says the charge is only at 97%. I don't see why it should be like this. Also when it's not plugged in the battery only lasts maybe 3 and half hours from just surfing on the internet. But I thought it was supposed to last like 6?(I'm thinking that since mine is an older model, that could be it.
View 2 Replies View RelatedMacBook Pro :: Battery Drains One Percent Per Minute
Jul 31, 2009Ok so to start off, my Macbook Pro is around 3 years old. With my original battery having been through 350+ cycles, I had to buy a replacement. So I did some research and found that the Fastmac battery was my best bet for a long-lasting, reliable battery. I would say that Ive had the Fastmac battery for a bout 6-7 months without any problems whatsoever. However, recently Ive been noticing the drastic change in battery life. I installed Coconut Battery yesterday and discovered that my current battery capacity is 2266mAh with the original capacity being 5800mAh and 213 cycles. I also should note that the battery drains 1% a minute with no programs running (besides the Activity Monitor, which showed no strange behavior). Now luckily for me, My Fastmac battery is under a 1 year warranty, however I just wanna verify that it is a fault with my battery and not anything on my Macbook's side causing the battery to drain so quick. The last thing I want is to receive my replacement and then have to go through the same process 6 months later.
Also here is the Battery Information from the System Profiler.
Battery Information:
Battery Installed:Yes
First low level warning:No
Full Charge Capacity (mAh):2266
Remaining Capacity (mAh):1414
Amperage (mA):-1449

View 1 Replies View RelatedMacBook Pro :: Battery Cycle Switches Over After 85 Percent
Oct 5, 2009I noticed that my battery cycle (according to istat) switches over at 15%. So as son as it switches over to the next cycle I plug in the adapter to make the battery run a cycle from 100%-0.(I know the cycle in 100%) But it still switches over at 15%, that means that the battery ran only 85% of its capacity. How can that be? Is it possible to reset (delete) battery cycle data?
View 2 Replies View RelatedMacBook Pro :: Battery Jumping From 85 To 0 Percent Instantly
Mar 5, 2010I have a 5-year-old PowerBook G4. I remember I changed the battery about a year or two ago, because when I used to take it to classes in college, and use it unplugged, my laptop would shut off in less than an hour (more like ~30 min) when it reaches ~30%. After I got a new battery, it went back to normal, and lasted much longer. In the past couple of days, I noticed that within about 5-10 minutes of using my PB unplugged, battery goes from 100% --> ~85%, and then all of a sudden shuts down.
When I plug it back in to a power supply, and it starts back up, it starts recharging from 0%... this seems a little extreme. I haven't noticed this problem because I almost have it plugged in these days, as I usually use it at home or at work where I have a power supply available, and I use it for a few hour period at a time. Does this seem purely like a battery problem?! (ie. it's just time for a new battery...)

MacBook Air :: Battery Loosing 20 Percent Charge During Sleep
May 7, 2008After all is said and done, and heavy Macbook Air use, there is only one thing still bugging me. Its not the slightly uneven lighting, not the 3 hours charge nor the 3:30 battery life I get constantly, nor the 6200 RPM fan. When I charge to 100% and let it sleep for 12 hours, I lose about 20% of the charge. Yesterday I was at around 25% and when I opened it this evening, 24hrs later, there was nothing left. If I leave the macbook air closed, I think that the battery would reach 0% after 3 days. This is not normal and some kind of leak.
