Bad Battery Capacity?

My macbook has a battery capacity of 86% and it is 10 months old. Is this bad? I get about 2 hours of batter life with wifi on, bluetooth off, screen dimmed. I need to know if this is good or bad.
I have a screenshot on flickr.

From what it says your battery is covered under the replacement guarantee if the update did not fix your problems.

Can a bad battery affect my MBP's performance, even when plugged in?

Well, as the title says... my battery status says "Service Battery", and although I know the instructions are simple ("dude, take your laptop's battery for servicing!"), a few months ago my financial situation changed, I'm trying to adjust the budget as much as I can for now, and I'm not sure I can afford to spend much money at the moment.
The thing is, my laptop's performance has been slowly getting worse all the time. at first, it was only with resource-intensive applications, but lately, even having more than 5 tabs open in Chrome gets the system all laggy. Now, as I've read on other threads talking about batteries being in bad shape, I would assume that, if the system can't draw much power, it can't work as hard, so a bad battery could be the culprit of such performance. However, if my laptop's plugged in, shouldn't it be drawing power straight from the outlet, hence being able to get all the juice it needs to feed both the 9400M & 9600M GT?
Ah! by the way, the info I guess I shouldn't post this without: It's a Macbook Pro 5.3, purchased in March 2010. This is System Profiler's Power section info:

Not necessarily, if the battery is trying gobble some power, as the bad batt is still in the charge/power circut. 446 cycles is quite a bit, and not a bad run, it also depends on how it has been used.
I would replace it ASAP as it is possible that it may create/cause more severe issues. A new battery is less $$ than more serious damage that could possibly result from leaving it in.

Macbook Pro 11,3 High End Retina battery capacity

HI,
As recent as 2 weeks ago I receieved a macbook pro that I purchased online. However due to the physical problems I had another one sent to me by apple. While waiting for the shipping company to pick up the problematic macbook pro I thought I'd compare the battery life on both of these units. to my suprise the old unit was performing better in terms of battery life.
New Macbook Pro 11,3 Capacity: 8688 mAh
2 Weeks Old Macbook Pro 11,3 Capacity: 8969 mAh
My questions are as follows:
1) Is this to be expected?
2) Should I complain and get it replaced again?
3) Anything I could do to increase the capacity on the new MPR?
Appreciate your input on this, cheers!
Happy holidays!

Great to hear :) I was really worried about my battery capacity as well when I got my 2nd mac.
The reason I exchanged my first one was it had really bad battery life. I tried all sorts of solutions and nothing seemed to work. It would always show I had a high battery capacity but the battery life was just terrible. I decided to exchange it and when I got my replacement I noticed it had low battery capacity. It turned out to be a great laptop it has much better battery life and it's capacity went up after I put a couple cycles on it.

Fluctuating battery capacity. can you give any tips to maintain my 596 cycles? (1 year old MBP 2012 13")

battery capacity went from from 80.4% to 78% to 86% within the same day. is this normal?
i alraeady have 596 cycles
1year old mac with applecare
before i'am always draining my battery, now that i knew that it is bad, what should i do now?
any tips and suggested routine?

Here is a list of Apple support documents regarding batteries.

Good or bad battery???

hi
i just bought a macbook pro 15" last week and im just wondering if i have a good or bad battery 'coz upon opening my macbook for the first time it suggested a lot of updates, including the battery update...so i did all updates...
i charged my macbook fully last night and used it this morning...i checked my battery status and says 99%-2:55 remaining...then after 97%-4:11 remaining...
i also check preferences....
full charge capacity : 5489
remaining capacity : 5407
amperage : -1496
voltage : 12294
cycle count : 3
i hope someone can enlighten me...
thanks in advance...

your stats seem ok.. i've gotten it as high as 142 hours temporarily, when its discharging.. the battery time to die measurement is at best an estimate..
what were you running that you were drawing -1400 amps? thats a bit excessive...
i run a problem called IBatt2 it has a grading system which compares your battery to the median of the same type of system battery... it will also show you the essential data...
my battery with 45 cycles, gets a "C" grade on their system.

Concerned about falling battery capacity on rMBP

Hello all, I'm starting to worry a bit about my battery capacity vs design capacity on my retina macbook pro 15". It's a early 2013 model that I bought in July. I know that apple guarantees the battery will have at least 80% of it's design capacity after 1000 cycles, but I'm worried mine is going to fall far short of that. Here's my coconut battery info:
As you can see, I've only had 60 cycles on the battery, the computer is barely half a year old, and it's already down 6%, under 8000 mAh. Should I be concerned/take it to the apple store? I know they won't replace my computer since I'm far outside of my 14 days, but still wondering if they'll do something. Will they even do anything before the battery falls below 80% design capacity?
I waited to post because I know battery capacity often fluctuates from 5% below to 5% above design frequently and will go up and down with use, but mine has steadily decreased, and has never increased. Every time I check coconut battery, it's 10-50 mAh lower than it was. My macbook does stay plugged in a lot, but I also make a point of using the battery at least once a week to keep the electrons flowing, and most weeks it gets off the charger more like two or three times. Often the battery will get used down to at least 50 or 60 percent before it gets plugged back in, sometimes even as low at 15 or 20 percent. I've tried draining it until it goes to sleep and then letting it charge to full again, but it didn't change anything. I didn't think it would, since lithium based batteries don't suffer memory issues, but I thought maybe it was just an error in measurement by the system.
Speaking of that, I did reset the NVRAM/PRAM and the SMC (multiple times). Only one of the times I reset the SMC did the light turn orange and then charge more, but it didn't change the max capacity number at all.
I see a lot of people posting their cocunut results/system information screen and finding they actually have above design capacity. Did I just get a lemon battery, or is it because I have it plugged in so much?
Thoughts? Thanks!

Apple guarantees that if your battery is well taken care of and not abused, however your battery looks fine.
You state: ~ As you can see, I've only had 60 cycles on the battery
Cycle counts dont account for much. People (some) leave their macbooks always hooked on power and worse still in sleep mode and on power and this can ruin a battery in "50 cycles", ergo it means little.
As for the 5% power fluctuation this means absolutely nothing since charge is just an estimate and the 5% is within that range.
Information:
Bad discharging or battery use conditions:
Heat (due to environmental conditions or due to rapid discharges from heavy use = gaming / video editing)
Rapid discharging of the battery frequently causes chemical changes over time in the battery leading to decrease capacity and resistance of current flow.
The very worst use of your battery is often draining the battery very low, and worse still letting it remain in such a state.
*Most long-term rapid damage to the battery occurs from discharging it with high loading (gaming) conditions but paramount is avoiding deep and frequent low DOD (depths of discharge) in use.
Undesirable charging or charged conditions:
High perpetual SOC (state of charge), where the battery is always or very often connected to charge
Parasitic loading where the battery is both usually on and charging or worse both always charging and in sleep mode, since this induces mini-cycling of the battery.
Bad general handling conditions:
Temperature use conditions when either too hot (95F and above) or too cold (50F and below)
Storing your battery away with a low charge (40% and less) long-term.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 25 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term.
Ultimately counting charge cycles is of little to no importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not to an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
(as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”. This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
The good news is that your Macbook has a safety circuit in place to insure the battery doesn’t reach too low before your Macbook will auto power-off. Bad news: if you let your Macbook protection circuitry shut down your notebook at its bottom, and you refrain from charging it for a couple days...the battery will SELF-DRAIN to zero (depending on climate and humidity)…and nothing is worse on a Lithium battery being low-discharged than self-draining down to and sitting at 0
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.

Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.

Battery Capacity Consistently Lowering

Hi all, I've been trying to calibrate my battery by running a "fully charged" battery down to sleep, the reconnecting and recharging top capacity (as instructed by the apple website for re-calibrating).
However, according to X Battery, the capacity keeps going down. It was 3.978Ah a couple tries ago, went down to 3.701, and is now down to 3.560Ah. Anyone know what might be going on here? The high, 4.809Ah, occurred around 30 days ago.
I bought the Powerbook in February, could the battery be going bad already?
Thanks!

A loss of capacity is a natural process for your battery to go through and the recent recalibration is made the system give you the real state of your battery. Failing to recalibrate the battery often reports very old capcity levels. Having said that the decline of your battery has been rather steep.
There are a couple of reasons for this
1) You do in fact have a bad battery although I doubt Apple will replace it at this stage. No harm in trying though.
2) The constant recalibrating is accelerating the decay. While recalibration is a good thing is is not recommended that you do this more than once per month as constant depleting of the battery will erode its capcity at a much higher rate.
What you might want to note also is that the capacity reported at the completion of recalibration is affected by how fast you do the recalibration. I can guarantee you that you will get a lower capacity if you ran you PowerBook at 100% and full screen brightness (as fast as you can deplete the battery) for the whole time than if you deplete the battery as slow as you possibly could. The slower you can deplete the battery the better the result.

What is battery capacity? :-)

I am new to portable macs. What is the battery capacity? How can I make it full?

50% after that few load cycles & only 10 months sounds a bit bad.
First try resetting your PMU as follows:
1. If the computer is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait 5 seconds.
4. Press the Power button to restart the iBook.
Then Calibrate your battery.
If that doesn't work I'd be inclined to contact Apple Service.

Battery capacity dropping and changing constantly?

I recently purchased a MBP 13" a few days ago and downloaded coconut battery to check my battery capacity and it seems to fluctuate a bit. It has been approximately 5 days since I began using the computer. I haven't been keeping the display on the highest brightness (do sometimes, but only when plugged into the charger at home) and keep other power saver settings on but the battery is still at about 5570 mAh, is this good or bad? Coconut battery says this is approximately 96% of the designed 5770 capacity. It dropped down to 5536 just yesterday and has risen back to 5576 as of this post. Is this normal because my computer is so new and it can't exactly calculate how much it has, or am I draining the battery that heavily?
I use it for school daily, and return home with approximately a 35-50% charge (depending upon usage during the school day), and begin charging when it reaches approximately 20%. Should I be charging earlier than this? I know not to let it drop to critical levels such as 10%, but not sure when I should exactly start charing to maximize this batteries lifespan. Thank you for whomever answers!

The small fluctuations you're seeing in your battery's Full Charge Capacity are entirely normal and will continue, perhaps lessening somewhat as time passes. I still see fluctuations (up as well as down) of 2-3% in my two-year-old battery's capacity, though of course the overall trend is gradually downward. It began at 4805mAh (103% of its design capacity of 4650) right out of the box, and it has been reported as low as 4320. It's now at 4530 after 137 cycles (this battery is rated for 300 cycles, unlike yours which is rated for 1000). I don't check it but every couple of months, so it could very well have gone outside that range at times without my noticing. I suspect that part of the reported variation is due to calibration error (I occasionally go longer than I should between calibrations) and part is due to limited precision in the measurement. I just don't worry about it at all, and I recommend that you don't either.

Battery capacity after 10 weeks only 90% ??

Hello community!
I hope I'll get some information here, since I am a new mac user
Hope you guys can help?!
Here's the thing: I got my macbook pro in october 2010 (mid 2010 model)
I've been using coconut capacity monitor since the beginning and always monitored the battery life. Yesterday I noticed, that coconut says battery capacity is 90% of the original capacity! Coconut says that I did around 48 load cycles so far.
my question: What am I doing wrong here? I always try to work with the mbp until it runs out of battery; I don't plug it in before, no charging when the battery is not completely empty. How can it happen, that the capacity reduces that fast?
What should I do in order to preserve the battery life? Is it possible to restore the 100% battery capacity by recalibrating it several times (like the apple support page advices) ??
Thank you for you answers and your help in advance!!
Kind regards,
griesTraum

With 48 load cycles in only ten weeks, you're working your battery very hard. And always running the battery down to zero before recharging it is a bad practice that will age your battery prematurely. If your work and lifestyle don't require you to consume the full capacity of the battery almost daily, don't do it.
It's not unusual to see the battery's reported Full Charge Capacity (and consequently its "health") fluctuate up and down by several percentage points from day to day and week to week, particularly when it's relatively new. If you give the battery at least a little use every few days, it should be calibrated every two or three months. Calibrate it now or as soon as it's convenient for you, then try to keep it plugged into AC power most of the time, using the battery for just an hour or two every day or two "to keep the electrons moving," as Apple says. This will be an ideal use pattern for the longevity of your battery. If it doesn't fit your life, don't do it: the battery exists to serve you, not you to serve it.
The best summary of useful information about MBP batteries that I know of is here:
http://discussions.apple.com/thread.jspa?threadID=1764220
If after following these suggestions for a few weeks, your battery's health continues to decline steadily and rapidly, you may have a defective battery. But until it shows less than 80% health, you're unlikely to get anything from Apple other than a report that it is "within specifications." So if you think it may be defective, wait until it shows 75-78% health for a least a week or two, and continues to show less than 80% after a new calibration. Then take it to an Apple Store, where they have a specific test they can run on it, and ask to have it tested. If it's defective, you'll get a free replacement.

Battery capacity, rapid drop???

Hi everyone.
I have a 2010 Macbook Air 13".
Every once in a while I check the battery capacity through Coconut battery and through System Profiler (coconut battery always reports the same numbers).
For the longest time the battery capacity (not the current charge, but the actual capacity of the battery) sat around 99% of it's original amount. (Design capacity is 6700 mAh).
However, in the space of 2 incomplete charges (ie. charging from say 40% to 100%) over about 3 days, the capacity of the battery dropped to 96% and then to 93%. (Current capacity 6262 mAh).
This battery is supposed to still have 80% of its capacity after 1000 charge cycles and it is now down to 93% and I have 66 load cycles on the battery (the system is mainly used plugged in, but I make sure to use it off the charger a few times a month to keep the electrons moving).
What could be causing this? Should I just take the laptop in to have Apple check it? Or could the system be somehow mis-reporting the capacity of the battery. I don't think I should have already lost almost 10% of the battery capacity in a little over 6 months of owning it and less than 100 full charges of the battery.
It seems a bit odd to me for the battery capacity to be stable for months and then to drop so rapidly in the space of a few days.
Thanks everyone!

Lithium Ion battery behavior varies up and down from day to day. The design capacity is never actually realized in a consumer product due to manufacturing tolerances.
The life of a Li-Ion battery is usually considered to be 80% of capacity, but that does not mean the battery will fail at the point but that is just a number for determining charge/use time that is reasonable for most users.
Li-Ion battery life cycles vary from 350-1,000 full charge cycles. If you discharge to 50% and recharge fully, that is 1/2 charge cycle.
The recommendation for occasional full discharge, not actually FULL discharge but to the point the unit shuts down, and then fully recharging before use is to condition the charge reporting circuitry built into the battery itself. It does not actually condition the battery like it did in the old Ni-Cad battery days. If you click on the apple in the upper left corner, About This Mac, More Info, System Report, Power and the battery information look at the Condition...if it does not say Normal there may be a problem. You will also see the number of charge cycles, and the charge remaining and Capacity...the ratito of the two should be close to the reported charge remaining in the upper right portion of your screen.
Your battery does not really sound like it is bad...but see what the system report says about the Condition...if it is Normal, Apple is not very likely to do anything about it.

Mid 2010 MacBook Pro battery capacity at 89% with 64 cycles

Hello everyone,
I have a 13" mid 2010 MacBook Pro that I got around Christmas time. I downloaded coconutbattery a couple days ago and when i used it then My battery capacity had been 91%. So I thought that this was odd because of how new the computer is still (15 wks old with 64 battery cycles) so I read about how the battery needs to be recalibrated from time to time and after doing so (followed the directions perfectly) My capacity is now down to 89%. Should this be something to be concerned about or is this normal?

It's quite normal and sometimes a recalibration can see things go up as well as down

MacBook Pro Mid 2010 Battery Capacity

I've read a few threads about this, mostly about battery capacity rapidly dropping after an install of ML. I installed ML when it first came out, and just noticed the drastic decrease in battery life about 3 weeks ago. My capacity could have potentially been dropping since I installed ML (and I just now noticed it), or it may have just started a couple weeks ago when I noticed. I'm not sure.
Either way, my MacBook Pro (Mid 2010) now has a battery life of less than an hour, even with extremely light processor load. I contacted Apple about this, and the tech said that the battery was rated for 1000 cycles. I'm currently at 220, and my battery capacity is a pathetic 30%. He said that since I wasn't under warranty, there was nothing they could do besides replace the battery - which I really want to avoid since I'm a broke college student.
Is there anything I can do here? I understand that I'm not under warranty anymore, and this wouldn't be a problem if my battery was degrading normally. However, getting 1/5th of the recommended battery life is pretty sad. I've read that doing a clean install of Mountain Lion/Lion might help. Is there a way I can do this without having to back up all my files? I don't have an external hard drive or anything.
It seems this is a common topic in these forums. Any help or links to solutions would be great. If this is answered in a similar topic, I'll gladly delete.

New iPod touch bad battery life? Already tried tips and support said nothing is wrong...

I just got a new ipod the other day because my 4th gen had a really bad battery(it was very old). When I tried my new one out, I noticed it was just as bad. I tried all the powers saving tips but unfortunately they do not work. I called apple yesterday and they said it was fine( they looked at the battery through the diagnostics thing I think). Anyone know what to do?

We'll, I don't know a full charge, but it was at about 80-90% yesterday when I took it off the charger. All I did was listen to iTunes Radio and use my snapchat on and off and I got the 20% warning in less than an hour

PowerBook G4 12" Damaged by Bad Battery?

I have a PowerBook G4 12" 1.5GHz with a bad battery that is about to be replaced by the Extension Program. Can the bad battery have damaged the computer while it was in use in the computer? In early 2005, I purchased a brand-new PowerBook G4 15" 1.67Ghz which turned out to have a bad battery, but because at that time the battery problem was either not yet known or not yet acknowledged by Apple, the battery was not only used in the 15", but when it was sent back from Apple after the first of three service attempts, the bad battery was not replaced and was sent back to me and I, not having been informed there was a battery problem of any kind, continued to use the computer until its hard drive then its logic board failed. Eventually, I found out about the exchange program by accident (and was officially informed by Apple one year later, in June 2006; ironically, the 15" had been replaced with one of the first MacBook Pros in March 2006). I include this history because I have always wondered if the bad battery damaged the 15"'s logic board. Now this 12", which I just bought, whose bad battery has been installed for years is having major issues: the screen freezes within the first 2 minutes of booting from disk, hard drive or network boot image (it has never booted to the desktop since I've owned it); it heats up under the hard drive/near the video chip; when TDM is attempted, the screen stays black altogether and the 12" never appears on the host's desktop. It will boot into Open Firmware but not in single user mode. There is some kind of white sticky substance present in small amounts around the pins thar lock the battery into the well. For the record, the 12" is otherwise in seeingly flawless condition with no dents or other signs of being dropped and inside it is clear no one has disassembled it or even removed the topcase. When the battery is removed and the AC power connected it still won't boot. Sorry this is so long.

The actual runtime of a battery depends on several factors, including what you are doing with your PowerBook. Information on stretching out your battery's runtime is available in this article. For a daily planner, try using iCal in the /Applications/ folder, or dTasks if iCal won't do what you want.
