Calibrating a macbook prp battery

Should I calibrate my macbook Pro battery once a month or every two months and
how many cycles of charge does this battery have before I would have to buy a new one?

Note that "calibration" has nothing to do with extending or maintaining the battery's runtime capability. The only thing it does is make sure that the "remaining running time" estimate as provided by the system remains true, since it can drift off as the battery cells age.
A Li-Ion battery will degrade over time, whether you use it or not. More info: [The Battery University|http://batteryuniversity.com>.

MacBook Pro battery won't charge

Hi
I just bought a new battery for my MacBook Pro (a1226). The old battery had over 900 cycles and didn't hold any charge.
Apple quoted around £100 for a new battery which is about a quarter of what the machine is worth so I decided to look on eBay for a cheaper alternative. So for £20 my battery came along and all was well and good. The new battery appeared good, it held it's charge. I could get more than an hour of unplugged action out of my machine.
It now says 'Not Charging' and when I unplug the macg safe it intantly dies.
Here is what the computer says about the battery -
Now I have followed these steps regarding restting the SMC http://support.apple.com/kb/HT3964
Plus I have reset the PRAM.
Now I realise I have probably bought a dud battery off eBay but surely there is a better alternative than spending £100 on an apple one?
Many Thanks
Tom

"You get what you pay for."
Purchase another battery, return the old one and make the time to calibrate. All new batteries for your model MBP need to be calibrated within a week of purchase and/or prior to usage. You will need to read your manual or the KB Article.
Your other option: If you have AppleCare, give them a call & let them deal w/it. If not, take your MBP to your local Apple Store or AASP. Let them properly diagnose the problem and provide you w/a repair estimate.
this involves fully charging it and disconecting the power and letting the battery run down and then plugging the charger in, letting it fully charge and keep it at that state for a few hours.
Not quite right.

Dota 2 and Macbook pro battery

My early 2011 15 inch macbook pro battery drains while connected with 85w charger when i am playing dota 2. Dota 2 runs faily well with very little lag in almost high setting. Shouldn't 85w charger provide adequte power for gaming. Dota 2 is not even a very demanding game. I have only played few small 2d games in my pro and this may be the first time i am playing a 3d game. And also sometimes it doesnt drain even when i play 2-3 matches but most of the other times it drains in single match. I have yet to see it drain down 90% but still. What options do i have to fix this? I am graphic designer so i sometimes do video editing in my macbook pro and i m quite sure some of those renderings are more system hungry than dota 2 and no drain while doing that. Thanks in advance.

What do you mean it didn't work? Are you having a battery issue that the update did not fix? Need some more info. If you look at the webpage that I linked to, it advises to have affected batteries replaced.
Identifying an affected battery
Affected batteries will have one or more of the following symptoms:
Battery is not recognized causing an “X” to appear in the battery icon in the Finder menu bar.
Battery will not charge when computer is plugged into AC power.
Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300.
Battery pack is visibly deformed.
Note: If your MacBook or MacBook Pro battery does not have any of the symptoms noted above, your battery does not need to be replaced.
If you're replacing batteries every 3 months I would take a look at how you are maintaining your battery. Are you calibrating it when it arrives and then every 6 to 8 weeks afterword? Are you running graphically intensive programs? Do you have a lot of background process in your activity monitor that are taxing the system? Most folks I have seen post here find their battery issues resolved after a replacement, not recurring every 3 months.

MacBook Pro Battery - what is the best way?

I have tried researching this before i ask, but i am not fully sure, so i am here asking
I recently bought a MacBook Pro. I use it as my desktop (plugged to external monitor), so it is the computer i use all day long. Since I was a PC user before, i am used to disconnecting the power when the battery is full. Now i am not sure this is the best way for the MAC.
Since I cannot take the battery out in this laptop, is it okay to plug it on and off as the battery is either charged or needs charging? I read in a few a places that you can keep it plugged most of the time and that means that the computer will be using the power and not the battery power, is this okay to do, and is it accurate?
Any advice would be appreciated

Modern batteries do not have to be removed nor does the charger need to be disconnected once the battery is fully charged. It's perfectly fine to use the computer with the AC adaptor whenever you are able to operate near an AC outlet. Then operate on battery power when AC power is not available.

Macbook Pro battery goes from 100% to 93%?

Upon charging my MacBook Pro 13", it fully charges to 100% but not even a minute later, suddenly drops to 93% and then resumes depleting normally.
Anyone know of anything happening like this before? I recently just got my battery replaced so nothing should be wrong with it.

Have you calibrated the battery?

What is wrong with my MacBook's battery?

I have an early 2008 MacBook Pro. I had got it used, and It has had plenty of problems. When I first got it, it told me I needed to replace the battery, so I purchased a new battery for it, but it gave me the same alert. So I went back to using the original battery, and I haven't used the one I purchased since then. I also had to replace both fans within the computer because they broke and would create a bunch of noise. So recently, throughout the last few months, I had dropped my laptop multiple times from my couch armrest of about 3 ft of height. Now, my laptop is not doing so well. My battery status is "Replace Now" but it holds a charge (For a VERY short amount of time, though). Also, the MacBook will shut off randomly for no reason. When I am trying to restart it, though, If I just press the power button for less than like 6 seconds, it will begin to start up and the shut off very quickly. After 6 seconds, it will finally start up. I don't know if the drops had anything to do with it, I thought I should put that in. If you know why my battery is like this, please let me know. Also, if you have any idea why my laptop shuts off like this, please let me know. Thanks!

MacBook Alum battery heating up while being charged and used

MacBook Alum battery heating up while being charged and used at the same time.
Is this normal? Or is it only mine? :S

The battery itself as in the bottom left side of the notebook or the white magsafe adapter that is actually plugged in? Either way, it is supposed to get warm unless you are talking burning hot on fire. Then of course it is a little too warm.

MacBook Pro battery had accumulated more than a 1000 charges, and stopped functioning unexpectedly. Went and got the battery replaced. Just saw that SMC Firmware 1.6 update deals with this. Possible to get my money back?

The firmware update corrects an error that may occur, however the techs would have checked the condition of the battery prior to installing a new one. If the battery was questionable, the firmware update was really not too important.
You can check the battery condition by going to the apple, left side of the menu bar, About This Mac, More Info, System Report, Hardware, Power and see what it says about Cycle Count, Condition, Capacity: Condition anything but Normal needs to be checked and may need to be replaced.
The cycle count of 1,000 charge cycles is the typical life of a Lithium-Ion battery, the point at which the capacity drops to 80% of the as built capacity.

Your MacBook will reduce the processor speed while it is operated with the battery out of it. See Mac Support article http://support.apple.com/kb/HT2332 and http://www.gearlog.com/2008/11/applenotebooks_take_hugeperf.php

HT204347 Do you connect the charger in the MacBook Pro battery damage if using device ?

Do you connect the charger in the MacBook Pro battery damage if using device ?
i am sorry i not good speak english

Provided you are using the correct charger for your Mac (13" have a 65 watt charger, 15" and 17", an 85 watt charger), it has enough capacity to power the computer for normal tasks, and the leftover power can charge the battery at the same time. If you are doing something very intensive, there may not be leftover power, but the Mac will take power from the battery if needed. Once the battery is fully charged, the pilot light in the charger plug will change from orange to green and no further charge will be applied to the battery.
You can use your Mac plugged to the charger with no damage to the battery or the computer.

Follow these steps to see the battery cycle count:
http://support.apple.com/kb/HT1519
Then look at the table below to see the maximum number of cycles your Mac is rated before the battery is considered spent and needs t be replaced.
For your MacBook Air 2009 it is likely 500 cycles.

My macbook pro battery will not hold charge

My macbook pro battery will not charge. The laptop will only turn on after it has been plugged in to charge, and when unplugged it automatically dies. When plugged in the battery indicator is green and the top right corner of the screen says "Not charging". I left town for a week with the laptop off and I came back in town and it won't charge. What can I do to fix this?

If you are under warranty call Apple and get a case number.
