So, am I advised to keep my battery always connected?

Is it true that laptop users are advised to keep the battery inside even if they are connected with a power cable? I always plug it off and let my laptop to be powered only by AC cable when I'm at home...

As Kappy said it is safe and heres another good reason to leave the battery on while running from AC.

  • Please Advise On The Best Way To Keep Your Battery Healthy And Not Deformed

    I am a black macbook (mb) user and have had my mb for 37 months now. after a year and a half, my battery (the first one) was deformed and i was advised to replace it quickly. i was also advised to calibrate my battery occasionally and so i did after that. but in just over a year after i replaced my battery, it is starting to deform and swollen. i have been following the advice and calibrated my battery as advised. my battery is still in normal condition according to the system profiler.
    when i first bought my macbook, i was told NOT TO keep recharging my battery whenever i used it and the battery drains because this would make the battery's life shorter. i was also told it is OKAY to have the power plugged in. and so i did that. but it turned out that my battery had deformed from it. most probably from the heat but i don't know.
    i use my macbook regularly. i keep it switched on almost 24 hours a day and i keep it well ventilated (i sit it on top of iLap) because i have my internet on 24 hours a day and use the internet regularly. i am not planning to replace my battery just yet even though the battery capacity has gone down to 77%. it's expensive here. i will keep on continuing with the calibrating every now and then. now it might be the magsafe's problem that the battery is deforming too soon. one time, the magsafe fell from my bed onto the floor quite hard. and since then it wasn't working properly. sometimes it heats up and it becomes too hot to hold for long. at times the battery would say 0:00 (time left charging) but the light doesn't change to green so i have to plug it out from my mb and from the main plug and rest it for about 10 seconds and then it runs as normal. i know i probably need to change the adapter soon.
    anyway, i'm just asking. for someone who uses his mb regularly or everyday and almost 24 hours a day, what is your best advice on how to keep the battery healthy and in good condition for a long period of time?
    sorry for the rambling but thank you.

  • Is it advisable to keep the mac connected to the plug as often as possible while using it? (to keep the battery at 100%)

    Reading the advises on the battery (long) life it looks like the main parameter of interest for evaluating the battery performance are the cycle counts.
    This also means there it is better to always keep the battery charged while using the mac in order to never let it discharge consuming cycles.
    Is it really advisable? Aren't there some possible drawbacks in doing so?
    (Risks due to higher temperature, risk of battery malfunctions..)
    Thanks in advance.

    Welcome to ASC!
    In the ~15 years I've been lurking here, there seems to be one recurring theme to posts about battery failure: the statement "I don't understand why my battery died! I never use the computer on battery power!"
    As OGELTHORPE points out, use the battery every so often. I try to get 1-2 cycles on mine per month. How you do it depends on your usage pattern. I use mine at a museum where I volunteer one a week and the battery has more than enough capacity to power my MBP through my shift.
    Think of your battery in term of human muscles: if we do not exercise a muscle, it will atrophy and become disabled. So it is with your MBP battery.

  • What is the best way to keep the battery built-in last longer?

  • Can I use my iPad Mini while plugged in thus keeping the battery at 100%?

    Can I use my iPad Mini while plugged in thus keeping the battery at 100%?
    Or must I use it on battery all the time?

    Copied from Texas Mac Man ...
    The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    How to Calibrate Your Mac, iPhone, or iPad Battery

    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

  • Keeping the battery healthy

    Hi guys,
    I tried to look for an answer, but didn't get what I needed. This is my first mac, but I've already owned a laptop before. I use my mac mainly at my desk in ma room where it is always connected and recharging. I sometime bring it to school and use the battery for the day. My question is, is it healthy for the battery to stay connected this often. I hear it's a good idea to do a complete battery cycle once in a while, which I'm used to do.
    Is this enough?
    Thanks for reading.

    I did read it 3-4 times and I keep getting the conclusion that it does not need a calibration.
    Portables with built-in batteries
    Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article.

    Since i got a 2011 macbook pro (13-inch) i assume it's already precalibrated. I may have misread the article thought

  • Keep the battery inside the Macbook at all times?!

    So, there's this guy from the Apple store that told me "You are not supposed to pull out your battery. You only pull it out if the battery is bad. It could actually damage your computer by not having the battery inside." after he failed to make my battery come out (The clear plastic tab came off and I only got my macbook for a week!!). Is that true? Because my friend told me when I use the wall adapter I shouldn't keep the battery inside..Any help is appreciated.

    Of gosh no that is not right. You CAN operate (meaning it's possible) the computer w/o the battery in. It is not however, recommended. RUnning the computer w/o battery will decrease the processor as it runs in a safer type mode to reduce the chance of failure.
    Also keep in mind that when you have the battery removed and are using the computer a simple tug of the MagSafe (very sensitive) will cause the entire computer to turn off improperly and further risking damage.
    All Apple laptops are intelligent when charging the battery. Unlike some other things where it's bad to always have it plugged in as it will cause "overcharging" the Apple batteries do not do this. When it is plugged in the computer charges the battery to be full (or more then 95%). Once that is finished it stops charging the battery and runs off the power from the wall only until the battery falls below 95% then it will begin recharging.
    So all in all, you CAN remove the battery if you need to, but to answer your question you really shouldn't remove the battery...The only reason i've ever had to remove my battery from my MB or my iBook was to do work inside the computer (upgrading RAM/HD) and that has been over the course of 5 years.

    To many different suggestions as to battery life of the MacPro. Is there one way to keep your battery life, do I keep it plugged in to AC or do I not?

    To be honest, I would only plug it in when necessary. On my older 2009 MBP, I plug it in at night and it lasts me a solid 5-6 hours, if it needs to be plugged in during the day, I usually do it with about 2-3 hours left.

  • Should i keep the battery on when it is connected to the AC

    hello
    i have a question:
    my macbook is always vonnected to the ac,, i don't move it around"seldom"
    so i'm owndering,,will this affect my battery,,
    should i keep the battery on when it is connected to the AC?
    or should i remove it?
    thanks in advance

    Hi multiple 1,
    Modern battery technology now prevent battery becoming overcharged or create memory effect, so like First Magus said, it is ok to leave the battery in your macbook all the time.
    But apple also recommend user to use their battery once a while or calibrate to refresh the battery cell.
    Good Luck.

  • Laptop battery always on full, 100% when connected to AC

    Hi,
    I usually use my laptop on AC with battery removed. Last week I used it from battery, then connected the laptop to AC. If I remember correctly battery started to discharge to 90 something percent after a while, but now it is always on full.
    acpi -b
    Battery 0: Full, 100%
    I have the following packages installed:
    local/laptop-mode-tools 1.61-2
    local/acpi 1.6-1
    local/acpid 2.0.16-3
    local/linux 3.5.3-1
    My question: is it fine to have the battery always on full? Or was it better when it was charging/discharging automatically?
    Thanks

    Let me clarify myself. When the battery is in place and the laptop is running from AC, sooner or later you will see that the battery is fully charged. When this fully charged status has been accomplished, charging stops and battery starts discharging (let's say from 100% to 95%) then charging starts again. I think that was the way it worked some weeks ago. My experience in this very moment is that battery is reported to be fully charged. Always. No drop from 100%.
    I think the charger electronic prevent the battery from overcharge, but I don't know why is the change in the behavior described above. Was it a bug and now it's fixed or now we have a bug.
    Anyway, people contradict each other how to prolong the health of a battery, but I found that usually they say if one usually uses a laptop from AC the best thing is to remove the battery when charged to 50-60% and store in a dry place, and from time to time it's advised to charge/discharge it.
    Uh... what make is your laptop, for example I'm using a Compaq laptop so my laptop has a big Compaq at the base of the screen and nice big Q on the back.  I wouldn't be surprised if your laptop is a Dell.  Google for product reviews for your laptop:  So, since my laptop is a Compaq and it's a CQ60-420US
    I'd type
    CQ60-420us battery charge/discharge behavior
    or something like that into the address bar for chromium, and then press enter.
    EDIT:  The best way to use/store a battery, and you can quote me on this 'cause I took a Electrical engineering class last semester and know what I'm talking about, is to just charge it all the way up and then use it till it's almost out of battery power.  If you charge it when it's at half capacity it will eventually do bad stuff to the battery, or something like that.  Anyway, it's just healthier for the battery to have the chance to fully discharge per every full recharge.  You don't have to let it go all the way to 0%, 'cause your laptop will probably cut off if you do that, so let it get as close to zero as you feel comfortable with.
    A good program for keeping an eye on power stuff is wmacpi.  It's what I use, since conky isn't reliable on my hardware when it comes to the battery.  Install it thusly:
    packer -S wmacpi
    and run it thusly:
    $ wmacpi
    If you use openbox, like I do, you can add the following line to your ~/.config/openbox/autostart file. 
    wmacpi &
    Here's an image of wmacpi showing a laptop being run off AC power.

  • When not using battery often - good to let MagSafe always connected?

    Hi all there – little question to have a longlife battery: on the Mac Book the battery is not used very often. Usually its on its place with MagSafe connected. Usually it doesn't have to load the battery (red) because it charges only after droping under 95% (I think its told in the manual).
    So my question: is it good this way, that when using battery only 1-2 times per week, the capacity stays good. Or should I use it more often?
    iMac G5   Mac OS X (10.4.8)  

    I agree - using the laptop plugged in all the time does nothing for retaining the battery life. My suggestion is to use the battery, even if your sitting here working. I do this on a regular basis - a bit ago, I let the system go on batt while I was working until I got the low battery warning, then plugged in and will let fully charge, then start the cycle over again.
    Personally, I don't think that leaving it plugged in actually destroys battery life, BUT work with far too many people that just assume that because they don't use their battery (plugged in all the time), that their battery will fully function when they do attempt to use it. Keeping the charge/discharge cycle active as you use your system will keep the battery at it's best. All batteries have a finite life, usually great for about a year, after that they start to decline. At/about the 3 year mark, you can usually count on replacing them as battery life will have significantly degraded. This goes for batteries for just about everything using today's latest battery technologies (Lithium Ion, NiMH, etc).

  • Can anyone advise me how I can disable Connection Logging in Mac mail please it seems to have been added when I changed my internet settings thanks very much

    Can anybody advise me how I can disable "Connection Logging which has set itself up in Mail, when the settings were changed for internet connection I am running OSX mavericks  10.9.3 thanks very much

    I certainaly did not turn connection logging on but the effect was disastrous.  Mail would not respond as long as there was a slow connection. I figured this out through turning off all network connections and watching Mail spring back to life and let me search my messages.
    Normally if a connection is slow to respond, mail just lets the slow connection do it's thing while everything else operates largely unhindered.With connection logging turned on, your Mail app is a slave to the slowest connection to a mail server (I have 8 total)
    I had to crash mail over and over again to do a simple search of my messages until I happen to notice that this connection logging was turned on.  I found this thread, turned it off, now Mail works as well as it ever has (very buggy but usable)
    How dare Apple do that behind my back!?  After all the problems there are Mail, they have the gall to turn on logging and reduce Mail to unusable?
    I also deleted all the logs for a good house keeping seal of approvable.  They were here:
    Some day Apple might consider hiring a test team... instead of relying on all the users.

  • MacBook Pro keeps shutting down unless connected to mains power

    My MacBook Pro keeps shutting down unless connected to mains power, even when fully charged. I took it into Apple store, Leicester, UK - battery diagnostic shows good condition so they updated the system but that hasn't worked. I'm running OS X 10.6.8

    Thanks! I've followed your suggestion and so far my MacBook has been behaving for the past few hours without being plugged into mains power! Fingers crossed...
