17" MBP Uni - Battery (mAh): 12000 or 17000 - Check your batteries!

Hey All,
This may be very premature, but it would seem some people are reporting 17000(mAh) on their batteries after calibration, while most are reporting 12000(mAh) or so.
The few with 17000(mAh) are reporting a pretty significant battery life extension over the other people, but it has yet to be determined if this is due to proper calibration, or some lucky users are getting better batteries.
I encourage you all to take a look and post your results. Also, be sure to post whether you have calibrated the battery or not as it may have something to do with it.
Here's how you do this:
- Goto The "Apple" in the Top Left Corner, select "About This Mac"
- Select "More Info..."
- Goto "Power" on the side
- Copy all info from "Battery Information" (Don't need System Power Settings)
Thanks!

I think somethings wrong with this MBP, It's been slow since day one. I haven't calibrated the battery. I am assuming that in order to do so correctly you just follow the instructions that come up when you search the desktop help...
Also, for longevity and battery health, should the computer be plugged in and charging anytime it is possible or is it good to sometimes let it run off solely the battery??
How do you all treat your batteries?
Thanks in advance.

When I use my 5 year old MBP on battery it suddenly shuts off when the battery life reaches 88%. Anyone know why and how to fix it?

13 weeks MBP 13" Battery 85% ??

Hello people, i recently bought a brand new mid 2010 mbpro 13"
im worried about my battery health
85% (4906/5770) it was 86% couple of days ago and 96% about a week ago
28 cycles
13 weeks
i have calibrated 2 times but nothing changed, should i send to repair?
thanks!
is my battery messed

Hello!
My MBP 13" battery also have the same problem. After the recent sudden shutdown, the technical support told me to calibrate my battery.
While it was charging with the adaptor, my Full Charge Capacity was 5002.
and now that i have charged fully + at least 2 Hours, it became:
Charge Information:
Charge remaining (mAh): 4484
Fully charged: Yes
Charging: No
Full charge capacity (mAh): 4609
im also puzzled too~

MBP A1211 Battery Needs to be Services

MBP indicates battery needs to be serviced. Can I solve this by buying/installing a new battery. Note please that battery indicator shows full charge, which drops with use. Thanks for any help

Apple considers the battery in your MBP to be a consumable item - and it sounds as if yours is consumed. Get in touch with your local Apple Store or an AASP and see how much a new battery would cost - you don't say which model you have or if yours is a user-replaceable or non-user-replaceable battery, so I can't guess at the cost.

My late 2013 MBP Retina battery gets only about 4 hrs. What might be wrong?

My late 2013 MBP Retina battery gets only about 4 hrs. What might be wrong?

I found a solution!
Perhaps this is just temporary, but I have my display up and working again.
Although the symptoms are different were a bit different, the solution here worked:
http://apple.stackexchange.com/questions/120259/grey-screen-after-login-blue-scr een-of-death-from-cmdr
As I was able to connect to my HD via an external monitor, in the finder, I went to:
1. Macintosh HD --> System --> Library --> Extensions
2. From there I moved all of the files that started with ADM and ATI (19 in total for me) to a folder on my desktop. (You will need to enter your admin password for this)
3. Next was a restart.
4. Then my display started working again.
5. After that, I transferred the files back into my Extensions folder.
6. I then did another restart with my fingers crossed and breath held. It worked.
Also... During the last few days of trying to find a fix, I restored a Mavericks backup to my computer away from Yosemite.
I'm very sure this problem occurred when I put my MBP to sleep, disconnected the power in its sleep, while something was connected to a USB port and unplugging the USB device (for me an iPhone charger) while the MBP was closed.
I hope this helps the next person.

What is the battery mah of ipod shuffle 4th gen?

Im searching in the internet but i cant find the battery mah of my ipod shuffle 4th gen
Iwant to know it because i will buy a powerbank

I ran a few calculations to find the result. The battery in the 4th gen iPod shuffle runs at 0.17 watt-hours and at 3.7 volts. Converting that to miliamp-hours, you get 51.3 miliamp-hours. Since I originally did these calculations for my brother, I calculated some usage statistics as well. I have a 15,000mAh Anker battery (about a year old) that I use for charging my devices. I found that the Anker battery could theoretically charge the iPod just under 300 times. Even if you use it 12 hours a day, 7 days a week, the battery should last exactly 365.1 days. In short, any size of battery will keep it charged for weeks and weeks.

Question about maximum battery mAh

I posted a picture of my original and current battery health. It seems to be really good right as long as the current is higher than the original? Are there any tips on keeping my mAh higher than the original?

MBP 2011 - Battery Draining While Plugged In?

After playing Splinter Cell: Conviction for a few hours, I noticed the battery had drained a few percentage points while plugged in? Almost as if the graphics card and fans needed even more than what the charger could provide. This has happened more than once, and once I've quit, the battery has no problem climbing back to 100%.
Any help would be great. Thanks!

+*Any help would be great*+
None needed
This is how your machine should be running. There are conditions, generally under a heavy load, that may require more power than can be provided by the power supply alone. During these times, you may see your battery charge slowly decrease even while your machine is plugged in. This KB article refers to MacBook Pros with removable batteries, but it does identify the issue:

My MBP runs HOT - worst enemy of (my short lived) batteries, What To Do ?!

After researching why my batteries don't seem to last as long as they should ... my replacement battery only has 150 cycles but can only power my MBP for less then an hour and then usually shuts off abruptly without warning, I've learned that heat is the number one culprit to long battery life.
I DO use my laptop mainly with AC, but certainly use it on battery power a number of times a week. I do a lot of process intensive work, ie. photoshop plus it seems that when I'm doing back-ups, via either/or Time Machine or MOZY, the MBP gets very warm. I usually use it on an airy base or a fan cooled base, that however gets it's power via a USB port ... creating perhaps more heat inducing electricity through put?
I'm reluctant to use the MBP without it's battery, in case the power plug accidentally gets pulled.
So am I doomed to simply having to buy a new battery every 18 months? I'm going out of town where I might have to use my 'puter without AC so I feel I better get another battery before leaving.

TS3048 I changed the battery in my wireless keyboard and checked the batteries to make sure that they work. When I returned to my computer (the computer was already on) the keyboard would not work, no response at all. What do I do?

I changed the battery in my wireless keyboard and checked the batteries to make sure that they are good, I left the computer on while I changed the batteries. When I returned to the computer, the computer does not acknowledge the keyboard so I can't do any diagnostics. What do I do?

Hold the power key on the keyboard down for 5 secs to power off, tap the power button once to start. It should connect automatically.

MBP weak battery...

I've briefly looked through threads similar to this, but I don't think any of those apply. I bought my MBP in summer of 06 (so https://support.apple.com/macbookpro15/batteryexchange/ doesn't apply), and since then, it's run 353 battery cycles. It looks like all exchanges have to have <300 cycles, so I don't think I can get it replaced normally. However, the battery health seems unusually low...coconutBattery reports 30% health at the moment. The entire Power section of System Profile reads:
System Power Settings:

Is this something unusual, and if so do you think Apple would/could do anything about it?

Your battery is certainly on the way out, and 30% health is quite low. Even though your battery is not part of the recall, be aware that there are two 'replacement' programs for batteries, the recall, and a general acknowledgement that there are battery problems which is coupled to a battery warranty extension (to two years for Core Duo machines). You may have already read the page where that is explained.
Even though you have >300 cycles you are clearly far below the 80% health those 300 cycles should have held to. So, you need a new battery, and Apple might provide one for free. Call AppleCare (there are special prompts for battery problems) or visit an Apple Store. Be polite but firm. Worst-case scenario, you have to buy a new battery. But it's probable that will step up - their customer service is quite good.
Hope this helps...

MBP 17" Battery Capacity and Run Times : Survey

I've had 2 MBP 17's so far, and I'd like to get a general idea from everyone about their battery capacity and run times they are experiencing.
My first MBP17 had a Full Charge Capacity of ~5900mAh before calibration and PMU reset, and 6800mAh after. This translated to about 3:40 of run time under light load.
My current MBP17 had a Full Charge Capacity of ~5899mAh before calibration and PMU reset, and 6942mAh after (currently). This translates to about 3:48 of runtime....still trying to get some more real-world run time numbers under different loads.
This proves to me that it is quite critical to calibrate your battery and reset your PMU at least once to ensure that your battery is reporting it's correct capacity. I'd be interested to know what everyone else's batteries are reporting.

MBP in Battery mode...How long does it last?

Hi Guys,
I ve got MBP 2.0 w2GB RAM.
How long does the battery last if i am only doing surfing?
I was running an audio application called Ableton Live (which is similar to Garage but much much better) and it only last for 32 minutes.
I ve got Bootcamp, the other day I was running on XP and complained about the not having enough power . I only unlplugged the AC for 15 mins.
I double check the battery's serial against Apple's battery re-call program but serial is ok so it is not in re-call list.
thanks.
M

You should calibrate your battery: wait until the sign indicating "low battery" appears, then wait at least 5 hours (computer "sleeping") and finally charge the battery without interruptions until the battery is fully charged. During the charge, you can use your computer.
This procedure has to be done every month.
See under About this Mac (Apple menu), "more info", "power" (I think). There, you will see the actual maximum capacity of your battery. The value for a new battery is nearly 5500 mAh but can be a little higher.
Don't forget to turn Bluetooth off and to lower the luminosity of the screen.
