I have searched countless threads about battery health but I feel that each individuals battery health situation is so unique due to the numerous fluctuations.
I have a 2010 13" MBP with battery health of 92%. Load cycle: 13. and Age of 4 months( but i got it 2 months ago)
Should I be concerned with the battery health at this point?
i have a 13" mbp with 130 cycles an i use it extensively.its been about 6 months since i bought it and i noticed tht apple will cover my battery in warranty fr one year only if it has less than 300 cycles on it.
my problem is tht i typically use my laptop fr no longer than 4 hours at a time. which means i recharge the battery jus before the battery meter hits red an counts 1 cycle as complete.thts why i got less number of cycles on the battery
cn i continue doing this without any adverse effects to my battery and its life ??
I just got my battery replaced and after a full charge both istat and mac osx shows that there is only one cycle available. I remember that my previous battery used to have at least 60 cycles. Is 1 cycle normal for new batteries or?
View 3 Replies View RelatedThe title says it all. I have a new battery in my 2007 MacBook, but my computer still says it's at 237 cycles. Is there a way to reset the cycle count? It does say, however, the battery is at 100% health.
View 3 Replies View RelatedI 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 10 Replies View RelatedI bought a MacBook Pro 3 months ago, despite in the first charge I follow the instructions of the store. The problem is that my battery doesn´t complete the cycle of charge, if I disconnect my computer and the value of the battery decrease at 95% 96% 97% 98% or 99% and I plug again the charger to the MacBook Pro, the battery doesn´t charge at 100%. I followed all the instructions of synchronization but the battery remains the same.

So first off, I absolutely love my MBA. Now that we have that out of the way. Since day 1 I've noticed that the cycle count on the battery seems to be climbing MUCH faster than it should.
- I've had the machine 51 days. I was out of the country without it for 9 days so really, I've had it for 42 days.
- According to iStat and System Profiler my battery's cycle count is 37
- According to System Profiler my battery's health is "Good"
- According to iStat my battery's health is at 98% (It started around 96%, has been as low as 94% but seems to have settled in at 97 or 98% for some time now)
- According to system profiler my maximum charge is 5006 mAh. (It's also gone up a bit since the machine was new).
I thought the definition of a cycle was the equivalent of 100% depletion of the battery -- whether that's one long unplugged stint that sucks it dry or 10 really short ones. A cycle is the same as using ~5000 mAh of battery power. I've been really good about keeping it plugged in while I work (the outlet is conveniently located). I've run the battery most the way down maybe 5 times. I do, however, run it down 10 or 20% almost every day as the machine travels with me in sleep mode or spends the night unplugged in sleep mode at my girlfriend's place).
I haven't done any careful testing but it seems though that if I run the battery down just 20% or 30% or so and then charge it all the way back up the cycle count increases by 1. Considering I've only used it for 42 days, and the cycle count is already at 37, I'm worried that it will hit 200 cycles by the time it's 8 or 10 months old. Isn't the point where battery performance starts to wane? Anyone else out there notice a rapidly climbing cycle count?
I had some issues with battery drain while sleeping awhile ago but that problem has been solved. However, ever since that incident I could not be paranoid about the battery life etc.I heard people saying that leaving the charger plugged in is simply fine as long as I do the regular calibration once or twice a month or so. Yet, Apple stated that they do not recommend the laptops to be plugged in. I will be going to a college this Sept and I really do want my laptop to last at least the whole 4 years.
Ever since I have contacted Apple customer service about this Battery issue I have left my Macbook charged up and plugged in while using and letting it sleep. One thing I have noticed is that the battery indicator says 99% and doesn't increase or decrease yet the green light is on. Is that normal? Since this is my first Mac ever and also first Laptop I would like some advice on how to treat the Battery( I know how to do Calibration and such). Is it better to do full cycle usage of Alum Macbook battery than leaving it plugged in all the time? (I unplug it when the Macbook is off).
i have an older C2D MBP on its second battery. I don't normally use it on battery power so my cycle count is pretty low. I have attached images. It is telling me to service my battery. Should i be getting a new one? if so, how are the NuPower batteries @ OWC?
View 2 Replies View RelatedI have my Macbook late-2006 and suddenly the battery do not charge at cycle 103. I tried to talk to guys at Apple Store but the only thing they can do is to sell me a new battery. In fact, the battery was in recall before 2009 but I was not be able to send it back at that time. If the battery die only at cycle 103, is this normal?

View 1 Replies View RelatedI got rained on and my macbook got soaked. I dried out my macbook in an airtight container with some special salt for a few days, and luckily got rid of most of the water issues with my monitor. Unfortunately, my battery or logic board seems to have not been so lucky. My macbook is a one and a half year old 13" unibody, and now won't turn/stay powered on unless it's plugged in. For the first 15 minutes I've plugged in the magsafe charger, the battery is recognized. It says it's charging but stays at 0% (I then get the X over the battery icon). The weird thing is that my previously health battery now has a 0 mAh charge capacity and a 0 cycle count. Is there ANY possible solution to this, or has the damage already been done?
View 3 Replies View RelatedI have a 2 year old aluminium macbook and have recently been having problems with the battery.
Sometimes when running off the battery alone, at around 20% battery remaining (or so it says) my macbook suddenly shuts off. After I start it back up the indicator says there is no charge left and shortly shuts down again. After plugging in the charger and checking coconut battery my battery health is suddenly 40% less than the last time I checked.
I am confused as to what the "battery health" of my MBP is. I downloaded an app it told me it is 89% but it is not consistent with the cycles, mAh capacity, etc (it should be more?), so I am thinking the app might be innacure in reporting this (reviews say this). I just want to have a second source to see where I stand.

I bought a 2009/2010 MBP a couple of years ago (still have AppleCare on it) and the battery life on this machine has been absolutely atrocious. I feel like I unplug it from my desktop and sit down on the couch and thirty to forty minutes of web surfing and i am down to 25%. and i have to plug in or I will get a warning that i am under 5% in another 10 minutes.Does anyone know if this is partially or fully due to Parallels? I just checked and with not much running all i see is a prl>vm_app that is taking up 12.6% CPU.
I mean I hesitate to ask this because I ran a test about six months ago by fully charging it and turning it on (no apps running) and my recollection was that it went into deep sleep in about three hours. This was when it was doing nothing.Any facts to measure this against or any way to do an actual analysis on my end? The cats at the genius bar are always like "situation normal" which makes me think there is something wrong with this class of machines or something.

I was looking into buying a new macbook pro and I was just looking at my current macbook 13 inch and I hadn't checked my battery health for a while so I went and had a look. I was extremely suprised to see my battery had done 1046 cycles and according to istat, my battery was at 92% health...
I have had my macbook 13 inch since november 2007. It has been having a few problems lately with over heating but I was wondering if it was normal to have a battery that had gone through so many cycles and still have around 4-5 hours battery life (when I am just browsing the net and doing uni work i.e not watching movies or listening to music)
I've had it for 16 months and the battery has 192 cycles and its health is now 78% (it fluctuates a bit). Is this health normal for this amount of cycles and age?

I have the Black Macbook (purchased in 2008) and within the past month, I have been experiencing problems with the battery. I've noticed lately it becoming weak, not being able to last long without being plugged in. However, now when I plug it into the charger, it shows 0%, and if I disconnect the charger, it automatically shuts off. I checked the System Profiler, and the condition of the health shows "Check Battery". What are my next steps from here? I don't want to purchase a new battery, in hopes to get a new Macbook later this summer. Does my Macbook have much life, or should I go ahead and brace myself for a new one?

I just got a Mac Pro Octo 2.93. It has a 4870 card and 4 1tb drives. I also have a Sonnet E4P e-SATA card installed. Would a 780 Watt 1200 VA surge suppressor be enough?
The other question is about waking the computer up. My old G5 Quad (7800 GT card, E4P card, 2 500gb drives and 8gb RAM) would wake up and while the afore mentioned surge suppressor would beep, the room electrical breaker wouldn't be tripped. Using that same suppressor for the Mac Pro results in the breaker being tripped when the computer wakes up. Would getting a bigger suppressor help with this? In other words, does a unit with a bigger battery capacity allow the battery to take the extra load when the computer wakes up preventing the breaker from tripping?
I bought a 3rd party battery for my MBP. I put it in and after cycling the battery i noticed that the full charge capacity was only 3990mAh (supposed to be 5500mAh). I returned the battery today and got and an upgraded replacement. this shows the full charge capacity at 4995mAh (supposed to be 5600mAh).
is this normal. Do I just need to give it some time or is it something with the batteries.
Just wondering, but how rare is it to have a battery that lasts 3 times longer than the "rated cycle amount"? Apparently this battery should have been dead 600 cycles ago... I am finally now noticing a slight loss in overall battery life.
I have used this MacBook 100% of the time since the day I have gotten it over two years ago. Is this why it has lived so long?
I've been having an issue with my Macbook Pro, it keeps turning off while on battery power while I am playing a game (Starcraft II) despite having sufficent charge remaining. It won't turn back on until I plug it back in. Usually when I turn it back on the time and date are reset and the password to my wifi has to be rentered. The most recent time this happened after I plugged it back in the battery still had 79% charge remaining. I've tried recalibrating the battery and resetting the SMC both which did not solve the problem. The system report states that the battery's condition is normal and I ran a hardware test which also came back normal.

As the Title of The Post says, i need to know if Apple Hardware check, Does check the hard drive. I'm getting a little bit more frequent hard drive clicks so i want to make sure my HD is not failing. So i need to know as so as possible if Apple hardware check looks for Hard drive Problems. And if it does not. Can someone point me into some Utilities i can use?
