Will it wreck my macbook pro battery if i drain it.

i have learnt that it doesnt wreck macbook pro battery if i leave it plugged it in all the time, but i was wondering would it wreck it if i drained the battery down to approx 10% and then charged it all way back up and kept doing it? if it wrecks the battery whats the point of having a 7 hour battery life like it says?
all advice is appreciated.

The battery is designed to be cycled. It is not necessary to do this more than once a month or so.

In fact it will. If you want it to last, cycle it about once a month.
Don't leave it plugged in all the time, nor should you leave it in a fully charged or fully discharged state for extensive periods of time (several weeks). That will kill it just the same.
from
http://www.apple.com/batteries/notebooks.html:
Apple does not recommend leaving your portable plugged in all the time. ...
... and
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.

The best advice is not to obsess about it. Like any well-designed tool, Macs are designed to be used.

Will this wreck my macbook pro?

hi,
i have bought diablo 3 for my macbook pro,
i was wondering how long will the macbook last off charge when playing this game? because if its like 2 hours then if i play the game for 6 hours a day im gonna be getting through 3 life cycles per day which is gonna wear the battery down pretty quickly :L
also if i leave the macbook in charge constantly when playing diablo 3 will this wreck the battery?
i used to have an old samsung laptop (2008) and i left it in charge all the time and now it has a 2 min battery life!
any help would be appreciated.
thankyou.

No it won't wreck the battery but since Diablo III requires a constant internet connection and has a hefty graphics requirement, the battery will go pretty fast. Why play unplugged all the time? I'd guess somewhere in the 2 1/2 to 3 1/2 hour range BTW but that's just an educated guess. I don't play on battery - much intentionally.

My MacBook pro battery totally drained

My MacBook Pro battery was totally drained on Jun 11, 2013. Now the date for everything says either Today, Yesterday, or Jun 11, 2013

Hi there. You might want to do a pram reset. Command/Option/P/R while starting up holding down the keys for three chimes. If that does not help do SMC reset.http://support.apple.com/en-us/HT201295 Then check date and time in system preferences for set date and time automatically.

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.

Can anyone recommend a USB CF card reader that will work in my Macbook Pro Retina? My USB card readers for CF cards do not work

At present, the only way I can load photos from a CF card to my new Macbook Pro Retina is by loading them onto an external hard drive via an old PC that can accept either of my USB card readers, then plugging the external hard drive into my MBP. Neither the USB card reader or the cable that comes with the Canon HDSLR camera will transfer photos directly to my MBP. I find it unbelievable that I have to go to a PC to load photos because I can't do it with my new MBP.
Has anyone found a reliable USB CF card reader, or one that connects via thunderbolt or HDMI, at any price, that will work directly with the new MBP Retina?

This is what we need:
Location photoshoot - we use the Canon EOS 5D Mk II still camera & the Canon FX100 pro camcorder.
CF cards are: SanDisk Extreme UDMA & SanDisk Extreme Pro UDMA 6 for video (I think they are both Type II) My Mac recognises them both as FAT 32 format
My MBPRetina is on the latest version of Mountain Lion OSX 10.83
the files from the camcorder will transfer to my MacBook Pro Retina directly via the camera's cable but it is quite slow & it means I cannot continue to film while downloading files but this we can live with.
the files from the still camera Canon EOS 5D Mk II will not transfer directly via the camera's cable - have yet to get the Canon software to download, but via the camera's cable will not help anyway as we need to have the still camera free to keep shooting.
We need to be able to take out the CF card from the first part of the shoot & download the still shots while just on the Macbook's battery power, while we insert a fresh CF card back into the still camera to continue with the next part of the shoot simultaneously (while the first card is downloading.)
The files from the first part of the shoot will be both in RAW (.CR2) & Jpeg format. We just need to quickly transfer the jpegs, then I do a quick sort, batch the best ones as black/white images, & use these in a client slideshow immediately after part 2 of the shoot.
Obviously we need fast data transfer speeds, & rely on the MBP's battery power while on a location shoot.
The card readers I have tried are an older specific CF card reader branded as Palm, & a USB 2 multi card reader branded as Travel Flash. With both readers, the lights on the readers flash on & off, & the MBP recognises the card & the files will even appear both in Finder & in i-Photo, so it starts importing, then aborts with an error message saying:
'The Finder can’t complete the operation because some data in “” can’t be read or written.
(Error code -36)'
& another message saying:
'the disk was not ejected properly'.
So it appears the MBP does read the CF cards but the card readers don't stay connected, no matter what angle I put them on or however many times I re-connect them.
Yes, they are probably cheap & I want to buy a decent one.
So, in summary:
the card reader needs to work when the MBPR is only on battery power (I read in some forums that some USB card readers aren't so reliable on the laptop's battery power)
the card reader needs to be quite fast. I have read the USB 3 readers won't read CF cards at higher than USB 2 speeds. Is this true? Are the firewire connected ones faster, & if so, are they still reliable on the MBP's battery power?
From research, it appears my problem is associated with my specific model of Mac & platform, being MacBook Retina on Mountain Lion OSX Version 10.83. If any of the recommended card readers have been successful with this, plese let me know.
Thanks heaps for the suggestions so far.

Pretty nice change for those C2D's

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

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.

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.

Can I solve a 2011, 13', macbook pro battery problem

After a local area power cut, my 2011 13' Macbook Pro battery symbol in the menu bar instantly showed that there was a problem with the battery, which had previously shown a 98% charged (full), but now advised me, via a help document that appeared when I clicked on the symbol, that I would need to get my battery serviced as it is not running/charging properly. Perhaps I was remis in not dealing with the problem sooner, but this morning, some 8 months later, the normal battery symbol simply has an X on it. The battery has completely died now and my otherwise incredible Mac will only work when conected to a power source. Is there anything I can do to 'reboot' or reconfigure the battery without paying for a new battery? Many thanks in advance for any help on this.

Try an SMC reset.

As you are aware, batteries (no matter what manufacturer) are consumable devices and is only covered for one year (barring any type of abuse). With your purchase date being in 2007, this would not be covered under your AppleCare extended service plan.
Suggest you make an appointment for your local Apple Genius Bar and they can perform a Battery & Adapter test. You can always start the process by contacting AppleCare (1.800.APL.CARE) and log down your case number after you have completed your discussions with them, so when you get to the Genius Bar, it will save you time. At that point they will be able to determine if the battery is defective and commence the replacement process. Include your case number in the notes section of your Genius Bar appointment form. This tests will check your MagSafe adapter and battery at the same time and takes about a couple of minutes if that. Hope this helps guide you through the process.
Cheers,
Pete

My 1 week old macbook pro battery is dying.

my 1 week old macbook pro battery is dying. i charged it to 100% then went to bed and this morning it is at 32% when turned on. What the heck?

my light does not flash in sleep mode.
Which means it isn't sleeping. Run the Console and put the computer sleep. Experiement with the sleep command and closing the lid. Does it sleep with the sleep command but not the lid? Does it not sleep in either case. In the Console, by default, you'll see all the messages that are logged. Pay attention to when you close the lid or execute the sleep command and pay attention to the log entries that occur at that time and shortly afterwards. You might find a sleep terminated type message which will give you a clue about why it isn't sleeping.
There are also programs that are known to cause insomnia. At the head of my list are all it one printer software because the drivers often constantly look for an incoming fax or the keypress from the AIO printer console.
One more thing - if you have been putting it to sleep and then disconnecting USB or FireWire devices - that's the problem.

Recharging a Macbook Pro battery

Does anyone know how much voltage does it take to recharge a Macbook Pro battery?

The power adapter can handle 110/220 volts AC input. Output to the MBP will be 6.86 volts DC at idle and 16.5 volts DC maximum.
Ciao.

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.
