Time to replace battery

Hello there,
My macbook pro has been shutting down suddenly-without the low battery sound alert. This has started happening recently-since last 2 weeks. I have read thru the forums here, but frankly there is so much info, i am
am confused. The capacity/time wise i get in the menubar is "35" minutes remaining, but then all of a SUDDEN...macbook shuts off. My battery cycle is way over 300, and holds about 83% capacity(coconut battery).
Here is my battery info:

Do i need to get the battery replaced? Does my battery has still some life left?
Any help/suggestions would be appreciated.
Thank you.

Calibration doesn't have anything to do with the health of your battery, it helps the computer more accurately determine how much charge there is left in the battery. Most of us partially discharge and recharge our battery and the more times we do this the more out of sync the the battery and computer become. Over time the computer's ability to accurately estimate the remaining charge deteriorates. Recalibrating the battery puts the two back in sync. Apple recommends that you recalibrate every month or two. I have an iCal reminder set up for it.

MacBook Pro -- how many battery cycles before time to replace battery?

Got a 5 year old MacBook Pro. There are around 95 battery cycles on the battery. It's the original battery. How many cycles should I expect before it's time to replace?
I ask because Checkmate is suggesting it's time.

Time to replace battery or iBook?

My iBook G4 800 is a little over 2 years old now. I noticed about a few months ago that once I disconnected the power adapter from the iBook, it will quickly lose its charge (about 45-hour) and by the time the power level reaches around...30-50% give or take...it suddenly just shuts down with no warning. So I'm unable to really calibrate the battery because I can't get to the sleeping mode point if my battery is failing on me by the time it reaches it.
Once it shuts down..I need to plug in the power adapter and press the power button to restart the machine. So I was wondering...has the time come to replace the battery? (2+ years seems like it would be time to so) or is the problem more related to the actual iBook?
Any help would be greatly appreciated. Thank you!

Luis,
You can still use the battery but keep in mind: showing a 100% capacity in the Finder's menu bar actually means only 39%. The capacity will wind down accordingly faster so have a look on the battery status and let the % rate be shown. A replacement may be necessary but you can keep one battery as reserve and exchange the two now and then to keep them alive.

Time to replace mobo battery?

Hi guys,
I'm replacing A64 3800+ with Opty 180, and 2x512 PC4000 Crucial Ballistix with 2x1GB OCZ 3200 memory. I have this mobo working since December 2004.
Wouldn't it be also a good time to replace mobo battery? (Would anyone know what battery brand would be best?)
Thanks in advance.

For the the small cost involved it won't hurt. Any CR2032 name brand will do: Sony, DuraCell, Eveready.
Edit: They can last from 2 to ten years but every 3-4 years is a good idea to to replace it.

Time to replace the battery?

I have had my ipod touch 4G for over 2 years. It has been working great, but lately it won't hold a charge for a day. I dont have anything running. At first I thought it was just all the app updates since iOS7. Now I am wondering if it's time to replace the battery? I use my ipod a lot.

It is up to you whether you want to shell ourt for batter replacement or just live with the shorter battery life.
Apple will exchange your iPod for a refurbished one with a new battery for $79. They do not fix yours.

A third-party place like the following will replace yyur battery for less. Google for more.

I ordered a battery for my laptop because it said to replace battery soon. How long can I let the new battery sit around as I wait for the old one to run out of more charge?

I ordered a battery for my laptop because it said to replace battery soon. How long can I let the new battery sit around as I wait for the old one to run out of more charge? Will the new one become less effective if it sits around too long?

How much capacity is remaining on your current battery?
Check your power status
From the  menu: Hold OPTION and click System Information... èHardware è Power
Copy and Paste in your reply.
The new battery will become less effective if you store it in a hot or humid environment. It should be stored at room temperature (22 C).
Long term storage (6 months):
Apple recommends that you store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life.

I got a replacement battery, reset the SMC, and my computer will still turn off unexpectedly.

Early 2011 15" Macbook Pro, 2ghz iz, C0*****F8V.
My original battery wore down to the point where it would not be recognized as available and the computer couldn't power on without shutting down in a few minutes. I ordered a replacement battery, certified Apple genuine, but after 3 days it reached about half charge and the computer died, not turning back on without the adapter. When it did reboot the battery was at 0% and not charging, and the computer was incredibly slow and laggy.
I refunded and returned this battery and got a new one. I've had it installed about 2 days and the computer will still turn off if not plugged in at about 80-85%. I have reset my SMC multiple times and my PRAM as well. coconutBattery says nothing is wrong with the battery.
What can I do? I'm a freelance video editor and this is basically calling me out sick from work for a week now.
Thanks!

upon the extended test.
Do these codes refer strictly to the battery, or to possibly other components that interact with it?
I can not give you a definitive answer to that. The 'x's' which I have marked should be letters. If so, could you provide them and that may give us a clue:
If that is actually what was generated by the AHT, then I am a bit surprised.
At any rate, the bottom line is that the MBP does not like your battery even though the output information that you provided does not indicate anything adverse. An Apple battery should correct your problem, I would think, but there is an alternative that I came across yesterday that you might consider. OWC. a Mac oriented vendor, is now selling replacement batteries for MBPs.
http://eshop.macsales.com/item/NewerTech/BAP15MBU78W/
Based on the reputation of the company, I personally would be willing to try their non-Apple branded replacement. I have dealt with them a fair amount, so my statement is from experience. Note that is has a 1 year guarantee as do the Apple batteries. ( I will need a replacement for my 2010 MBP and I will probably purchase it from them)
Ciao.

Where do I buy a replacement battery for a MacBookPro6,2

After 1504 cycles, the "Replace Soon" warning has shown up on my mid-2010 MacBook Pro. I am 100% capable of replacing the battery myself, however I can't find anywhere on Apple's website to buy the replacement battery. All it says is to bring it in for them to replace which is not an option for me at this time.
Does anyone have a SPECIFIC recommendation on where to buy a GENUINE replacement battery for my model? And please don't say "ebay" or "amazon".
Here are the specs on my model: http://support.apple.com/kb/SP582

Apple insists on installing the batteries in unibody MBP's them selves and will NOT sell you the battery otherwise. Your alternative is to make an appointment or ship the MBP to them.
Yes, it is easy to install the battery. I have taken mine out a couple of times.
Ciao.
I'm looking for a non-Apple, non-ebay, non-amazon source for the battery. My Macbook Pro is in use 12+ hours per day for school and work so sending it in for a replacement is also not an option. So strange how it's impossible to find this battery for sale from an online retailer. Macmall, OWC, MacConnection, PowerMax, SmallDog... nobody sells them. :-(

Where can I procure a replacement battery for a MacBook Pro model 6.2? I've tried Other World Computing without success.

This is for my wife's 15" MBP model 6.2.

Hi, I read the post about calibration and I probably do that a little too often TBH! As I get so little time out the battery and mainly use my MBP on my lap, usually with the power supply near by, it gets charged to full, run to empty to the point of sleep, or sometimes it even cuts out and then is recharged to full again, so I really think it's new battery time. I've seen non Apple Official ones for between £35 and £65 that have 3 year warranties and state they are around 5200mh but am unsure due to reviews.
Later...
Anyway's I have now ordered a non Apple replacement from Amazon for about £35 and it has several good reviews and 4.5 out of 5 stars so I'll see if it works and report back. If it doesn't I'll send it back and get the Official Apple one.

Bought a NuPower replacement battery, but can't get my MacBook to see it.

Hi Everyone!
Bought a NuPower replacement battery and installed it. Rebooted and the fans are running at full tilt. Did a SMC reset and a PRAM zap. Shut down. Restarted and the battery icon still has an X in it (no batteries available). Fans are running fast as well (again).
Repeated this a few times, but still can't get the MacBook to see it.

It has been less then 48 hours that I have installed the new battery and it's still not charging. It says that I has 51% of charge, but it has not pass that number in the past 48 hours. I have reset the PRAM and SMC and no change.

Genuine Lenovo Replacement Battery Does Not Charge

After reading the number of people on this forum who experienced the same problem I faced (my T61p 9 cell battery went from fine to dead overnight), I took the advice of the contributors and purchased a new, genuine Lenovo replacement battery from a seller on e-bay. I compared the new battery to my original battery and here's the test results for each of the 2 batteries;

After charging the replacement battery overnight, the battery gauge never went above showing 24% charged. I unplugged the AC adapter and it went from 24% to its current level of 5% in about 15 minutes. After plugging the AC adapter back into the computer, the battery will not charge.
Any advice would be greatly appreciated.

It is hard to be sure without seeing it, but best guess is that the battery charging circuitry on the motherboard has died. If you still have remaing warranty, now is the time to use it.

Fan runs constantly after installing replacement battery

I received my replacement batteries on a timely basis, charged them as instructed and get proper running time from them.
My issue is that suddenly the fan runs almost perpetually. I have zapped the PRAM, stared at the console utility looking for a problem, and watched activity monitor. All seem normal.
The CPU now runs at 140-142 degrees all the time. It would spike there occassionaly before but only when I knew I was pushing hard. Even connected to AC hoping that will vent the machine better has not helped.
Is it the replacement battery or just coincidence? Suggestions appreciated.

You might also try a different battery if you have access to one. Unfortunately, many of the replacement batteries being shipped by Apple are defective. They don't fit properly into the battery bay. I suspect that if the quality control is this poor, then it seems likely that other problems will arrise as well. Check carefully that the battery itself is not overheating. Another possibility which also happened to me is that after installing the last upgrade to the operating system, one or more of the third party widgets became problematic, causing the same problem you describe. After removing all third party widgets, the problem stopped. Good Luck

Replacement Battery sent by Apple NOT WORKING (!)

Hi everyone,
A couple of months ago I received the infamous Apple email stating that if your computer was so and so, then you probably needed a free replacement battery. I thought this was great since I had been one of the unlucky ones whose computer had burnt out because of this a year ago. At the time (last year) my computer was barely 4 months old, but it was udner warranty. After the replacement, I still noticed the computer became really hot really fast, and after my warranty was over... I prayed.
Now, a month ago I got the new battery for free. Swell. I calibrated it. Didn't really work. Should've taken the hint. Then, every time my computer would turn on, the glorious "your date has been set..." message would appear. Should have taken the hint. Finally this morning, ladies and gentleman, my computer died on me for an hour. Did the 3 beeps.
After trying everything, I finally did a PMU reset and now my computer has come back to life. The battery still friggin' hot, the clock still in 1969 (I reset it now).
SO: what should I do guys? I'm petrified that this computer will die again, and it sure will. All my work is in here, AND all my homework (I am a college student). Of course, today i'm gonna back everything up just in case, and I'm gonna contact Apple about the new battery presenting the same symptoms as my old one, but in the meantime, any safety suggestions?
Thank you so much and sorry for the long email
Jorge

Call Apple and tell them what you have experienced. I had the same problem with a replacement battery after about 3 weeks. The battery was the problem.
I have my second battery now and all is well. They were very friendly and the specialist knew I had tried all the possible solutions like downloading the battery update, reset the P RAM and PMU even repaired permissions and took the battery in and out many times. They sent a new battery which took about 10 days. New batteries can be defective, the one I got showed 12 recharging cycles. Good luck.
