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 Repliesi 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 ??
The 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 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 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?

I have a 2009 Macbook Pro, and Apple advertises up to 80% battery capacity up to 1,000 charges. My MBP is down to 75% health after a little more than 500 charges.Would I have any problem getting Apple to swap the battery out for me free of charge?

View 16 Replies View RelatedI just got my MacBook pro returned 4 days ago after the hard drive was replaced because the brightness was on minimum and had to be reboot 15 times so it could be changed. I asked apple to replace my battery because it had 1 minute battery life and it had 47 cycles but they didn't. My mac didn't have enough power to start speakers so I rebooted but my mac went into sleep mode and wouldn't come out. I had to force shut down. I tried turning it on but it wouldn't turn on, I tried taking out battery etc and pressed power button 5 secs but nothing changed.
I live 100 miles away from apple repair. I wrote this on my iPod touch. I took it to apple repair and it turned on. I had been using a 65 watt charging cable for a MacBook, I need a 85 watt charging cable. It was 100 miles away and has been posted to me today. apple told me that a MacBook pro requires 80 watt charging cable, and 65 watt can be bad for the mac and will only work if the battery isn't dead. my battery was dead when I tried to turn it on.
My battery keeps on acting up and needs to be replaced. I don't have applecare. I was wondering what the price would be for me to get a new battery.

Is there such an application built in mac os x or a downloadable? I already have coconutbattery, but that does not give me the uptime numbers. I know there is one in istat, but it keeps going on if the computer goes to sleep.
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 Macbook Pro from 2007 (aluminium keyboard). Everything was working great until a couple of days ago, when I replaced the battery.
No every time I choose to shut down the computer, it will restart and NOT shutdown. I have tried several things - the only thing that seems to work is to unplug the power chord - then it will shut down, but if the power plug is connected, the computer basically can't shut down - it just restarts.
I made a mockup of what the MBP 13" would be like if Apple ditched the superdrive, used a bigger battery, and added a dedicated GPU:
(actual) 2010 MBP 13"
(mockup) 2011 MBP 13"
I figure the larger battery would add another 5 hours to the current 10 hour battery life, totaling about 15 hours, although that could change with the addition of the more powerful GPU.
The little white plastic doohickey that opens the battery compartment on my laptop (powerbook g4, I thinks) has broken off and now I can't open the battery compartment.I'm trying to find out if my battery has the appropriate serial number for the recall, but I can't open the battery compartment. Plus, the battery no longer works at all, so I have to use the AC adapter if I want to use the laptop at all--NOT GOOD!Does anyone know if this dumb little piece of plastic can be replaced, and if so how? (I'm sure it costs something like .000000003 cents to manufacture......)
View 8 Replies View RelatedRecently started getting the Date & Time Error message when bootup completed to desktop each morning when starting up ol' PMG4. PMG4 is gigabit ethernet model with GigaDesign 1.3MHz CPU upgrade and running OSX 10.4.10. After a few days of this, I realized that internal battery must be going bad (although replaced it 2 years ago...). Had local Mac shop replace battery and for about a week all was good... Then message came back again! And then a few days later one of my internal hard drives went bad and crashed and icon disappeared from desktop....coincidence or ???
Anyway, took my PMG4 back to shop and they put in another battery for me....thinking that maybe battery wasn't so good that was put in. Guess what, still getting that error message every morning at bootup that Mac's date and time is set before 2001, etc. Any ideas as to what's causing this??? wasn't doing this until just recently.
tried 2 boot up my G4, nothing, replaced internal battery, no status change, advice? would still like to be able to use it if possible and affordable

Is it true that when we charged 100% battery and it says on AC power, does it LITERALLY do what it say? i mean the power of Macbook pro is not provided by battery but by magsafe instead. is it?last thing, leaving the Macbook connected to the working magsafe isn't add numbers up to cycle count right? and is it okay to charge the Macbook pro all the time and only using it when we could't find AC power outlet?

I have loved and cherished my MacBook Air for two years now, but last night it went in to a reboot cycle for no apparent reason. Now every time it gets to the apple logo I get the rotating "thinking" ident under the apple logo and it restarts, continually. I did the hardware test (holding down "D".....that was fine.) I also reset the PRAM... so the troubleshooting keystrokes work.

I have a macbook pro 13 inch purchased in 2009. My HDD died so I took it to an Apple dealer and they replaced it and upgraded me to 10.6.8, when I took it home I found that some of the applications I had received for free were now missing, and after a few days I was having the same problems with my HDD (folder with ? mark appearing) so I took it back. They told me that I had a virus? They then gave me the apps that had been missing and upgraded me again to 10.7.3 however it is still freezing regardless of whether I am on the internet so its not my connection. I also went to open itunes and it told me it could not find a folder and to choose a location. When I chose Music - itunes - it states I can't and to choose another folder.

After I replace my super drive with Hitachi 500G 2.5mm HDD, I can not boot except I hold the option key and manually selecting OS X to boot. I think if I am able to reset HDD as 1st boot device as HDD like modifing BIOS in windows machine, it might help, how I don't know how.
