Macbook OS X 10.5.8 battery problem. Advice needed...

Hi all,
I have a Mac OS X version 10.5.8 bought summer 2008. It recently had a new hard drive fitted and since then it says (Not Charging) and 0% where it normally charged fine. It could be a complete coincedence that that battery no longer appears to be working properly since coming back from the shop but it seems a little odd.
It is plugged in properly. I tried doing an SMC reset to no effect. The battery is four years old and I guess it could just be dying a natural death.
As it stands, I can use the laptop so long as it is plugged in but if I accidentally knock the power cable out the laptop immediately switches off.
It is less than ideal. Can anyone help me?
Thanks a lot,
Rebecca

Thanks for getting back to me.
Here it is...

Macbook Pro 13' early 2011 SCM/battery problem on Mavericks

After updating to Mac OS X Mavericks I started getting problems with battery/charging of my laptop. Mostly when I touch my laptop after inactivity it just crashes, i see black screen and when I push power button it restarts. What's more, after black screen power adapter stop charging my laptop (power led does not work) until I manually do shutdown and wait some time.
One time I even had a problem when after restarting (from black screen) fans go maximum and macbook stopped seeing battery. Only SCM reboot helped.
On Mac OS X Lion everything was great. Such things appeared just after updating to Mavericks.
Thanks for help.

You are right but thats crazy !! The whole battery is there to be consumed if needed without harming my system . Else apple should force macbooks to sleep mode when reaching this 20% !! I charged my battery when it reached 13% instead of 0% for only one time and see what happened ....
note that difference in mah in just one cycle !!! stupid batteries & chargers

Macbook (late 2013) 13" retina display battery problem

I recently bought a macbook from BH photo & video, around november. I used it basically everyday since, but I noticed that my battery was very short. Like for normal use (minimal browsing, youtube, etc) the battery percent goes from 100 to 83 within just 30 minutes. At 100%, the indicator says I only have 4 hours of battery left. Is this normal? If it isn't... are all macbooks covered under 1 year warranty? Because I want to bring it to the apple store to get it checked out just in case. The only thing that comes up to mind as a cause of this is that I leave it plugged in when I'm using it, but only because I use it as a desktop. Either way, I heard that leaving it plugged in won't hurt because the battery automatically stops charging once it reaches to 100%.

A new Mac is in warranty for 1 year from the date of purchase.
A new Mac comes with 90 days of free tech support from AppleCare.
AppleCare: 1-800-275-2273
Call AppleCare or take it to the Apple store to have it checked out.

Battery Problems - Replacement needed?

Hi everyone!
I've not posted on this forum before but just thought here would be the best place to come to ask for expertise and opinions!
Okay i'll cut to the chase!
Roughly 18 months ago I purchased a lovely Macbook Pro with the Macbook Pro Applecare too.
In January 2009 I realised that the battery wasn't too good health wise.
Since brand new battery life was roughly 3 and a half hours
Since January 2009 the battery lasted roughly over an hour/hour and a half.
Since May 2009 the battery barely even lasts 30 minutes. (iStat Pro says my battery health is 14%)
As you can tell, I am quite annoyed at this! (details of battery information below as of May 2009)
Charge Information:
Charge remaining (mAh): 768
Fully charged: Yes
Charging: No
Full charge capacity (mAh): 781
Health Information:
Cycle count: 267
Condition: Check Battery
Battery Installed: Yes
Amperage (mA): -202
Voltage (mV): 12213
In January I enquired about the battery and would I be able to get a replacement for free due to being covered by the Applecare, but I was told by the man at the Genius Bar that I would have to pay full retail price for a new battery due to batteries not being covered by applecare and the complimentry 1 year warranty was the only thing that covered the battery health.
I read that "Apple claim a battery should retain 80% capacity after 300 cycles" and that getting in touch with customer relations may be a good idea. Can this be applied to my battery information?
Is there anyway I can get my battery replaced by Apple? Or is it a case of paying an obscene amount of money for a new battery which would do the same after 18 months?
Thank you for any help! Additional information if needed will be gladly given!
Chris.

Well another problem - probably related - has occured!
Hopefully, if I can wangle it a bit, would this be able to get a replacement battery under Applecare?
When I do use my Macbook Pro and it isn't plugged in, even though it barely lasts 15 minutes now the "Reserve battery power" window pops up on screen, even when the battery status indicator (top right of the screen) shows that there is 3/4 of the battery power left 2 or 3 times in 5 odd minute gaps (black too).
Due to this error, and Applecare wanting to solve almost any problems encountered with Macs, would I be able to - if I use craftyness and ingenuity - be able to get a replacement battery?
Is this a good idea or not?
Thanks for any help, and thanks to Kappy for replying!

Lenovo B560 Battery problem! Need help asap

Hi, I have a big problem with my Lenovo B560.
Recently I started noticing the charging icon in the bottom right corner of the screen would go briefly from "charging" to the icon for "not plugged" (just the battery). If I moved the power cord a bit it would go back to normal.
Days later it happened again but this time a little more persistent. I didn't give it much attention. And then suddenly, last weekend it stopped charging altogether, despite being plugged. I tried different power sources, I tried moving the cable around, nothing. With the little time I had left before it completely discharged, I googled the problem and saw somebody in a thread saying "it's likely tha battery, it needs replacement", which made sense to me, since my laptop is 3-years old.
I ordered a replacement battery and waited. Today it arrived and I put it in, eager to use my computer and have everything going back to normal. I turned on the computer, battery was at 50% but it still did not charge. It showed the battery icon like before, as if it weren't plugged in. I moved the cable around again and noticed it would briefly flash back to being plugged. And then it stabilized on "plugged in, not charging" but it was suddenly at 3%. However, at least it didn't go down this time.
I tried reinstalling the Power Management Driver, restarted, everything was the same. Then I went to Device Management, I disabled the Driver and the icon dissapeared. Restarted, reinstalled driver once more, icon was still gone.
Then I noticed in another thread somebody recommended taking out the battery and turning on the computer with just the power cord plugged in. So I took out the new battery and turned it on with just the power cord. And it worked, and that brings us to the present moment. Both batteries sit next to me and my computer is currently working simply on the power that is supplied by the power cord.
Can anyone please tell me how to get out of this mess? My job relies greatly on this computer working, and I need to fix it asap. Any kind of advice is welcome. Thank you!

Update: the computer will not turn on anymore, not even with just the AC cord and no battery. Please help.

I have constant K8N Neo2 problems advice needed. (long) Update

I need some advice on what my problem might be and if I need to RMA the motherboard or power supply.
I have a new Athlon 64 3500+ processor, MSI K8N Neo2 Platinum BIOS v1.3 motherboard, with 2 512MB DIMMs of Corsair Value Select Memory. I have had and am still having a series of crashes and lock-ups I will list below. FULL SYSTEM SPECS BELOW AT BOTTOM.
I initially installed the motherboard with a SINGLE 120GB hard drive from the old machine and the installed the memory in memory slots 1 & 2 to try dual channel memory mode. I then formatted the C partition and did a clean install of Windows XP Professional with SP2, installed the MSI drivers on the installation CD that came with the motherboard (Nvidia nForce3 Version 5.03 System Drivers, Realtek gigabit ethernet driver, Realtek AC97 audio driver) & the GeForce v66.93 video driver. I then got my first blue screen "MACHINE_CHECK_EXCEPTION" crash, I ignored this crash and rebooted. I shortly got a black screen crash which I also ignored.
I then installed a new 200GB hard drive and a old 120GB so I could transfer the data from the old 120GB to the new 200GB drive. The data transfer went fine. As I was preparing to install some applications I then got my second blue screen "MACHINE_CHECK_EXCEPTION" crash. Suspecting the Corsair Value Select Memory could not handle dual channel I ran Memtest-86 for 2 passes and got NO errors with the memory in dual channel mode, so I left it.
With my data backed up on the 200GB new drive I removed the new 200GB and the second 120GB hard did another clean install of Windows XP Professional with SP2, this time with Nvidia’s nForce3 Version 5.10 system drivers, the Realtek gigabit ethernet driver and Realtek AC97 audio driver from the motherboard installation CD & the GeForce v66.93 video driver. I downloaded the latest version of Core Center and installed it and got it working. CPU temperatures were showing a low of around 29C, average of about 44C, and spikes at full loads of about 55-57C. I then ran Ghost to back up the boot partition. I installed all my applications, reinstalled the 200GB and 120 GB hard drives moved some data around with no crashes.
I then installed Rome Total War and played for about 2 hours and had one black screen crash after the reboot played for 4 more hours with no problems so I shut down and went to bed.
In the morning I got up started the computer let it run for awhile the CPU temperatures were in the low 30Cs to low 40Cs I tried to copy some files from the D partition to desktop and the screen freezes I waited about 5 min. with no change and no drive light activity so I hit the reset button. Upon reboot I got a ‘no system disk found” error, I went into the BIOS and checked the drive set-ups and boot priority, everything was correct. I tried for a half hour to get the system to boot with on luck. I used the Ghost to restore the partition image I had made earlier and still no boot. I finally decided to reinstall XP again put in the installation CD and when I got to the screen where you decide where to install Windows I changed my mind quit and bingo the machine boots into the restored Ghost partition???? I started to reinstall my applications got one more blue screen"MACHINE_CHECK_EXCEPTION" crash and another screen freeze that I had to reset.
So I decided to start from real scratch I removed the new 200GB and the second 120GB hard drive ran Killdisk on the boot drive, made a new clean 20GB C partition and did another clean install of Windows XP Professional with SP2, this time with Nvidia’s nForce3 Version 5.10 system drivers, the Realtek gigabit ethernet driver and Realtek AC97 audio driver from the motherboard installation CD & the GeForce v66.93 video driver. I installed the latest version of Core Center and installed it and got it working. CPU temps were as before.
I tested the memory with Memtest-86 again 2 passes no errors. Just in case I then moved one of the memory DIMMs to memory slot 3 out of dual channel mode and to a slower speed and ran Memtest-86 for about 20 hours with 21 passes with no memory errors, so I think memory can be ruled out as the problem.
Next I installed my applications I got one screen freeze that I had to reset. I reinstalled the other 200GB and 120GB hard drives. After I got all my applications install and Ghosted the boot partition. I have had one more one screen freeze that I had to reset.
I have a problem I simply cannot figure out. The memory is obliviously fine. While I have seen CPU temperatures spikes as high as 57C the CPU temps as reported by Core Center averages in the high 30Cs or low 40Cs and most of crashes/lock-ups don’t seem to occur during high CPU load/temp. The power supply might be a little light for the system but many of the crashes have occurred with only one hard drive in the system. The fact after one for the lock-ups the system would not boot for awhile and then magically just booted gives me concern there might be a motherboard problem.
Any solution ideas would be appreciated. Should I RMA the power supply, the motherboard, or both.

Great isn't it (although not without the occasional crash)
Would you say it's better but not there yet ? or the same ?
I thought the same as Ibn Quote
Your PS unit is a little weak for that much hardware, but I doubt thats your problem as well
re your PSU, given youv'e got a less hungry Graphic Card, thought it was at worse marginal, have seen worse.
To investigate further it may be worth diconnecting one of your HD, maybe the 200gb for a time.
It's a small thing but it may be slightly better to have both your maxtors together on IDE channel 1, given their identical.
good luck - keeo us posted

My Macbook is becoming slow after 3 years. (Advice Needed)

Hi Guys,
I have had my Macbook Pro for around 3 years now.... It's starting to become slow.... I use alot of RAM gobbling apps like Photoshop, Flash, Logic X etc etc. I'm a student and I cannot afford to buy a new Mac right now so I have been looking into upgrading my system.
I have thoroughly cleaned out my mac and followed all guides on how to speed up my mac online etc etc. It helps for half an hour or so but once I'm using multiple apps like the ones mentioned above it begins to die so to speak.
I have looked online and have come to the conclusion that It may be best financially for me to invest in some new RAM and maybe an SSD drive?
Would you recommed this? rather than paying out £1000 for a new laptop (which I simply cannot afford)....
RAM - http://www.amazon.co.uk/dp/B0070C2ND8/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&col id=1IU0LK5EQNXPM&coliid=IV98M7PZWAEN6&psc=1
(Possible) SSD - http://www.amazon.co.uk/Samsung-500GB-2-5-inch-Basic-Solid/dp/B00E3915Y4/ref=sr_ 1_1?s=computers&ie=UTF8&qid=1398171607&sr=1-1&keywords=macbook+pro+ssd+drive
Would it be worth getting both or would the RAM be okay alone? Also any idea's how many more years this would give my Macbook? I'm hoping it will prolong it's life by atleast another 3 years running at a good performance....
also when I upgrade would it be worthwhile to back up my system and re-install the OS? Start back from scratch so to speak?
If you have any other suggestions I'm totally open to them and look forward to reading replies.
Thanks in advance, Josh.

By the way, ANY SSD drive will work on your MacBook Pro. If you do specific searches for "macbook pro ssd drive" most likely you'll get all the expensive price tags.
I currently use SanDisk Extreme SSDs and Mushkin Deluxe SSDs both are usually more economical to other brands and they both perform amazing...
The standard HDD on your mac usually goes at around 70MB/s (read/write) both of these SSDs go around 470/ 270MB/s (read/write).
So the SSD upgrade will give you a pretty good speed improvement...

Macbook Battery Problem

Hi all, this is my first post, but something weird happened to my macbook that I have to share with you.
Ok, my Macbook Core Duo 2.0GHz (1st generation) have had no problem during its first and half year. Then I left the notebook sitting at home for one month as I was away on business. Came back, the machine won't start, used AC adaptor and showed the battery not charging, "x" and everything. My warranty expired, so I bought a new battery. Once I got that, it worked fine for almost 7 months.
Another business trip left my macbook for 1 month, I came back, the battery is dead again!!! So I went to apple support and bought another new battery. This time I installed it at home, and it doesn't charge what-so-ever. I tried everything from SMU reset, PMU reset, P-RAM reset. NOTHING WORKED.
So I took a friend's macbook battery to try, and it worked! I can charge that battery with my macbook, and my battery won't charge on his macbook. So scientifically I thought its the battery defect. I went to Apple Care and they say they will replace it for me, but think that it should be my macbook's problem. Must be the Logic Board, I explained why I disagree, and that the battery came with only one LED blinking when I got home to charge, the current was already too low to charge.
Anyways, I was able to buy a second-hand battery really cheap but with limited life-span and use it until my replacement battery returns. Everything seem fine and I can charge it up to 100% although it will only last me 50-mins, still not bad, right?
I was reluctant to completely drain this battery now since I am afraid it will drop to zero and won't recharge like the other ones.
I am using Boot Camp, and Vista as well as OS X. Suddenly today, two days after I bought the 2nd hand battery, I was using Vista to show my friend the battery problem is fixed. But suddenly out of nowhere the battery dropped from 95% charged to 0% in seconds. It shuts down automatically, and the battery was flashing one LED indicating it's dying.
I started back in Mac OS X and found the charger able to recharge, but it fixed at 0% for 20 minutes. I thought I am screwed and went out for a smoke. I came back to see the battery charging back to 5% and then slowly to 10%, and 20%, suddenly it went back to 85% in seconds, and then 100%. I try to unplug it and it seemed fine. I left it on without the adapter for 20 minutes, the battery drain normally, to 70% (it's fine considering the battery was 2nd hand) My friend thought I should try to switch back to Vista to see if the same thing will occur. So I did, and before the Vista screen came up, the macbook blacked out. I checked the battery indicator and it's flashing one LED again!!!
So I switched back to Mac side and re-do the charging, this time it took longer to get back to +90%, I thought this is normal, 'cause I did use the battery longer on the Mac side before switching to Vista for the test.
I thought to myself, why Vista drained my battery, and then I remember the first battery that died on me was about the time I switched the PC side to Vista. Prior to that, the PC side was using XP. The second time it died it was in Vista as well. I also remember I wanted to reduce the size of my PC partition, so I trimmed off unnecessary features like hibernation by (Powercfg -h off). It saved 2G in size but it may be causing some problem to the charging circuit for the Mac-hardware??? Don't know for sure.
So I erased my Vista partition, and re-installed XP. Since then I tried both sides without adaptor, usually for 10-minutes or less, and no sudden dropped to 0% occurred since.
Everything else is working fine with my macbook, except the power features. Right now at least I can charge the battery, but I am always worried about when or IF the battery will dropped off and kill itself.
I am waiting for the replacement battery to return from APPLE, and hopefully when it returns, my Macbook will be able to recognize the DEFAULT low-charge of a new battery. I'm still not sure if my macbook is defective, and if it did killed the first battery replacement they gave me a few days ago. If it did kill a decent battery, will it kill this new replacement as well??
I know for a fact that the reason why the machine won't charge the battery is because the current of the battery has become too low for the machine to be able to charge it. If the current becomes lower, the "X" will occur suggesting that the machine doesn't even recognize it's a battery. But what I want to know is what caused the battery to drop to such a low current if I turned off the macbook during storage.
Sorry for the length of this post, but I have to be clear on all the details if I want help, I suppose. Right now my question is (1) Why is this occuring?? (2) Am I right in assuming that by removing Vista with XP, the problem will not repeat?? (3) Is it likely for any new or 2nd hand functioning battery to drop to the state of the other battery any time soon?? (4) Am I doing proper care for my Macbook, and what should I do in the future to avoid the same problem from occuring??

gpotts,
Thanks again, here's my battery profile: (keep in mind this is the 2nd hand battery I am profiling) BTW, something happened when I was doing this message, I left the notebook on for about 20 minutes, it dropped from +90% to 48%, macbook prompted me that the battery is running low. I plugged the adaptor and it went back to +95% within minutes...
Good thing is, I haven't seen the sudden drop to 0% ever since I removed Vista, and also I am able to charge my battery everytime I try now, no more "NOT CHARGING" or "X" indication.
Any clues??? Thanks in advance.

Battery Problems with MacBook

I've been following the various threads about battery problems with MacBooks.
I too have experienced a problem with my battery on a 2 month old MacBook.
It suddenly refused to charge. It showed a battery icon with a black X through it.
I followed various suggestions that I found through various posts and support pages - eg. resetting PMU etc., even downloading the deep sleep widget which I found difficult to get to work - but nothing solved the problem.
Yesterday I went in to the Apple Store in Birmingham and waited until I could talk with one of the tec experts (incidentally, they were very helpful even though very busy and I didn't have an appointment). The tec guy said he though that the battery was faulty. It didn't work in another MacBook they had. But another battery would work in my MacBook. So, I was given a new battery, which seems to work fine now.
However, I have read in various posts that people have had the same new battery solution which works, but then the problem reappears with the new battery over time. I will wait and see. If that is the case, then I think it will point to the problem not being with the battery, but rather with the system, PMU, OS X, motherboard or whatever. So, I think it makes sense for us to post any difficulties we have so that Apple can see that there might be a problem with the batteries in MacBooks and start working on a solution. Otherwise, it will probably cost them a lost of money providing replacement batteries !

Hey Christopher...
I posted the same in another thread. I'm not a big fan of duplicate posts... but it seemed appropriate in this case. Take a look at the last paragraph regarding discharging lithium ion batteries. I'm not sure if it would be the electronics in the battery that tell the MacBook it's time to charge, or the MacBook's power management unit...
"Talk about a jinx! I've had my MacBook since shortly after they came out (week 9). Never had any problems. I've calibrated my battery about once a month or so. It seems after my last calibration, I got the dreaded "X" in the battery indicator. My MagSafe indicator was green. System Profiler showed that there was no battery. I reset the PMU and the SMC firmware... also tried reseating the battery (one of those things you're sure won't work... but ya just have that little bit of hope anyway). Alas, nothing would bring my battery back. Took a trip to my local Apple store. I had made an appointment online, but still had to wait over an hour (they really need to enlarge their Genius area now that they have so many more machines out there). Told the Genius what the problem was... he swapped out the battery... but the one he tried was fully charged because he took it from a machine that was plugged in. So the tension was mounting... would it charge or not (I was hoping it was just the battery and not something else). He had me use my MacBook for a bit to drain the battery. I ran Parallels and did a Windows virus scan (that should drain the battery pretty fast)... After I got the battery down to about 90%, the Genius plugged it back in. To my delight, the MagSafe indicator went orange and started to charge the battery. With that, the Genius went in the back and got me a new battery. He had me stay there for a little bit just to make sure everything was okay. I'm sort of afraid to calibrate my battery now... at least properly as in letting it completely drain. I had done a few calibrations in the past without a problem, but it seems this problem tends to occur after someone does a calibration. I'm just happy it was just the battery.
I came across this little tidbit from the Battery University webiste:
Some lithium-ion batteries fail due to excessive low discharge. If discharged below 2.5 volts per cell, the internal safety circuit opens and the battery appears dead. A charge with the original charger is no longer possible. Some battery analyzers (Cadex) feature a boost function that reactivates the protection circuit of a failed battery and enables a recharge. However, if the cell voltage has fallen below 1.5V/cell and has remained in that state for a few months, a recharge should be avoided because of safety concerns. To prevent failure, never store the battery fully discharged. Apply some charge before storage, and then charge fully before use.
I wonder if there is a fault with some of the batteries that is allowing them to discharge below this minimal level, making them impossible to recover."

Battery problems on MacBooks

I am one of those affected with the battery problems on MacBooks, the battery suddenly died and has the black "x" displayed on top. The computer has all the symptoms explained in the website but I can't get a replacement. I no longer live in the US (I am in Germany) and the support people here tell me that this serial number isn't covered even though the website states that it is given the purchase date.
I am not sure if anyone here has found a way to fix this issue or is the only way to get a new battery? If so, does any one have an email of Apple Customer Support in the US so that I can send them an email explaining?

Contact Apple in your country. If you can't wait for Apple to resolve your problem then I would suggest just buying a new battery.

Macbook no longer "sleeps" after 'low battery' warning, just suddenly dies

My macbook (just over a year old) used to give me a warning with 10 minutes left that it would sleep so as my data was not lost, if I didn't plug it in. However, recently, it has stopped doing this - instead of sleeping, if I don't get to a power source in time within 10 minutes, it simply cuts out, with the sound of the hard drive stopping - like if you shut down a frozen macbook with the power button.
This is REALLY irritating - what's going on? Why does it not sleep anymore, and is there any way to fix it?
I'm on Tiger 10.4.11, with an intel macbook...

Same Problem here. Tried several calibrations, smc and pram zap (well i guess there is no pram any longer so it zaps something else). Now I found another post where they talk about the battry 1.2 update. http://discussions.apple.com/thread.jspa?threadID=1449128&tstart=60
I remember when trying to do an battery update to 1.3 manually the update told me that it is not for my macbook. But - I found the 1.3 update Bundle in /System/Library/Configuration/BatteryUpdater.bundle
1. I Removed /System/Library/Configuration/BatteryUpdater.bundle from my system
2. rebooted
3. Emptied trash
4. Installed update 1.2 by Softwarupdate.
I will now do an SMC reset an then let the battery run low and watch what happens.
Then do a calibration.
I have the problem here in different ways. Sometimes Macbook shuts down suddenly after low battery warning, sometimes it sleep, almost never it hibernates.
My Battery was replace after showing the x symptome about a year ago but now it looks bad again
Full Capacity (in mAh): 3866

Serious Battery Problem: Lack of Charge and Quick Drain

I have a 15" Macbook Pro purchased late July/early August 2008, model number A1260 and has its software completely updated. I use the computer every day and, aside from the occasional cycling after getting the battery charge down to 0%, charge the computer every night.
Recently, my battery seems to be dying a LOT quicker, with the worst case of me leaving my computer to fall asleep with "Better Energy Savings" settings activated at 72% charge and coming back after about 15 minutes of cooking to find that the computer had completely died. After plugging the computer in to a power source, it took 10 minutes for the charge to change from 0% to 1% and, after reaching around 18%, I unplugged the power source and plugged it back in, triggering a change in the battery monitor that made the 18% charge reading jump up to 81%.
According to the System Profiler, my Power statistics are as follows:
Charge Information:
Charge remaining (mAh): 3016
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 3512
Health Information:
Cycle count: 564
Condition: Fair
Any ideas on what the problem might be or what I can do to solve it?

Cycle count: 564
That's over 2 years of charging once every day cycles that you accumulated in just a little over 1 year. Personally, I don't recommend taking the battery down to 0%; it sounds like you have been 'riding it hard'. Batteries don't last forever.
If you purchased AppleCare, you can see what Apple says; without AppleCare, there isn't much you can do but buy a new battery.
Note that: http://www.apple.com/batteries/notebooks.html says:
For Apple notebooks with removable batteries — such as previous generation MacBook and MacBook Pro computers — a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles.
You are well over that.

Can Apple replace my macbook pro (mid 2012) retina's battery if I think that the battery health has gone bad/in need of and renewal?

I've had my Macbook for about 11 months now and i use it every day; its gone though about 420 cycles of charging and using the power, and i noticed the battrey preformance has decreased (as expected). The problem isn't sevear yet but it would comfort me knowing that i could replace the battery in the near future
Please contact me or answer the question if you know anything about this!

No only if they think under warranty/AppleCare, but your likely able to pay for a new battery if they have them, which they might not yet since it's such a new machine still.
BTW, I have a Early 2011 17" MBP, 27 months old, charges to 97% and has only 14 cycles.

After 300 cycles, is the battery problem considered normal?

I now have the dreaded "Macbook won't work unless plugged in" problem. Mine does recognize the battery at various percentages up to 100% and will charge it if it runs down (which it slowly will in sleep mode as I can unplug it then). Purchased the computer on June 6, 2006 (very out of warranty), and just started with this "can't unplug" issue last week.
After trolling this and other sites I have reset the SMU and the PRAM several times. Removed battery looks normal, no warping, and I am always updated on the software updates, so the battery update has been installed for a while now. I run maintenance scripts regularly as well.
I have calibrated the battery several times in the past but cannot now as it will take several days on sleep to run it completely down, and I need the computer daily for work as I am self-employed. I have always let it run down in the past to sleep mode, then plugged it in. I never used it plugged in while at 100%, until now since I have to.
Coconut Battery (which I just started using) says I'm at 3526 mAh of the original 5200, 67% capacity on a 100% charge. Is this typical at this age and usage of battery?
So battery cycles are at 307, plus I'm out of warranty. Is this behavior (can't run unplugged though battery is at 100% or will charge if lower) typical after 300 cycles? In other words, do I have to buy a new battery every year to avoid this sudden shut off if the magsafe cord is yanked accidentally during my work?
And I have read of others who get their battery with the same issue changed out under warranty--only to have the issue recur shortly later. Am I going to drop serious cash on a battery that will leave me in this same predicament in just a few weeks into the future? I really need advice on this one.

Thought I was preventing battery memory issues by running it off the battery so much, definitely won't make that mistake again.
The memory thing has been going around since the Ni-Cad days. Li-Ion doesn't have that problem thank goodness. Here is some info that may also help you with your next battery.
It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate. You should calibrate your battery once a month.
The following links have good information about the MacBook and the care of it's battery.
