Is it ok to leave a macbook charger plugged into the outlet at all times?

Even while not charging?

Your battery will last longer before needing replacement if you let the battery work once a week or so. Think of it as a muscle: if not used. it begins to die.
Please see these Apple recommendations for battery maintenance:
http://www.apple.com/batteries/notebooks.html
especially the section, "Standard Maintenance" (my emphasis added):
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month. Need a reminder? Add an event to your desktop’s iCal.
I take my MBP with me once a week to my volunteer job at a museum. When things are slow I use my computer on battery. That way I know I get the electrons moving at least once a week.
There are many posts here that start with, "I don't understand why my battery went bad after only a year, I never use the battery"

  • I left my iphone 4 on charge plugged into the wall, would it be safe to leave for 4 days?

    Is the phone safe to be plugged in and left for 4 days?

    Under normal circumstances, I'd say yes, but as with any piece of electronic kit, if you're going to leave it unattended for that long, unplug it and shut it off to be safe.

  • My iPad2 won't charge when plugged into an outlet.

    My iPad 2 won't charge when plugged into an outlet. I've tried 12W and 10W original Apple iPad chargers as well as iPhone 4 chargers. It charges (very slowly) when I plug it into my laptop but I've tried every outlet in my house and at work with no success. So I am stumped as to why it won't work in two completely different locations when plugged into the outlet - because it's obviously not the charger, cable or the iPad batter.
    I've tried blowing out dust from the port, resetting my iPad (holding down the home and power buttons at the same time) and jiggling the cable.
    Note: I am still on iOS 6 so upgrading my OS isn't the issue.
    I would appreciate any assistance with this as it's very frustrating!

    If it will charge when connected to the computer, but very slowly, typical of a low power USB port, but will not charge with the chargers you have tried, the issue is then most likely with the chargers.  However, to be sure, take the iPad and charger and cable to an Apple store genius bar and have the technicians test them to see where the problem is occuring.

  • Is it okay to leave my MagSafe charger plugged in while not charging my MacBook Pro?

    I have a MacBook Pro and it came with the MagSafe charger.  I have the charger on a power strip that I turn off when not charging the computer.  If the charger is in a well-ventilated area, is it okay to leave the charger plugged into a live power source without the computer being charged?  In other words, would the charger overheat if I leave it plugged into a live power outlet.?

    Understand that, to maintain battery health for the long-term, you need to use the computer on battery power once or twice a week so the battery gets some "exercise." I use my MBP 13 away from home twice a week and do so on battery power alone as current batteries hold a charge longer than my time away. That seems to be keeping my battery in good shape.

  • Leaving Macbook Air plugged into ac adaptor?

    When using the Air at home, is it ok to always leave the computer plugged into the AC adaptor, whether in sleep mode or in shut down mode? The magsafe plug on the computer stays green because the battery is charged. If I unplug the ac adaptor, even for a day without using the computer, the plug is first amber as some charging takes place.
    What is the best way to use the computer at home to preserve battery operation over the long term?
    thanks

    Some other users already hit on the main points...
    One thing worth mentioning, the purpose of the MacBook Air was to be super portable and I'd imagine for the typical user who purchases the machine they're anticipating being very mobile with it. I know on mine, I've already crossed the 100 charge cycle threshold and the machine is only about 3 months old. I use it a lot, both plugged in at night and unplugged during the day.
    No matter how you use your battery, charge the machine, or leave it plugged in, ultimately the battery's longevity will be depleted. There are ways to prolong it, but it's impossible to prevent it. My advice to you, is to use the machine how you see fit.
    Regarding charging at night, there's no evidence to support that leaving the machines plugged in overnight (on, off, sleep or otherwise) is problematic. I personally unplug mine at night, unless it requires charging. But again, that's a personal preference.

  • Is it OK to leave my iPad charger plugged in (i.e., charging)

    Is it OK to leave my iPad2  charger plugged in at full charge when I'm in one place for long periods? If so, should I still cycle the battery down once a month as recommended for the Mac Book?

    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
    http://www.macblend.com/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.

  • It rained in my window last night, on my power strip.  My macbook adaptor (charger) and iphone adaptor were both plugged into the strip.  The power strip is dead.  Iphone is fine.  Macbook will not boot up and charger light doesn't go on.

    It rained in my window last night, on my power strip.  My macbook adaptor (charger) and iphone adaptor were both plugged into the strip.  The power strip is dead.  Iphone is fine.  Macbook will not boot up and charger light doesn't go on. I borrowed another charger and still no luck.  What should I do?  (Charger wasn't plugged into Macbook until I dried it off.)

    Spill Cleaning
    And, don't think that just because it was two teaspoons and not a glassful that there is a difference.
    Some liquid has just spilled into your Mac. What should you do?
    Do
    Immediately shut down the computer and unplug the power cord.
    Remove the computer's battery (if you can)
    Disconnect any peripherals (printers, iPods, scanners, cameras, etc.)
    Lay the computer upside down on paper towels to get as much liquid as possible to drip out.
    Note what was spilled on your Mac.
    Bring the computer into an Apple store or AASP as soon as possible.
    Don't
    Don't try to turn it back on. Liquids can help electrical current move about the components of your Mac in destructive ways.
    Don't shake the computer (this will only spread the liquid around).
    Don't use a hair dryer on it (even at a low setting a hair dryer will damage sensitive components).
    Do not put in a bag of rice in as much as rice will get into the ports and optical drive and do further damage.

  • I can't turn on my MacBook Air despite trying to hold down the power button and using the SMC method. BTW my battery charger lights up to a green when plugged into the laptop.

    Hello cass528,
    I would be concerned too if my MacBook Air would not power on.  I recommend following the steps in this article when experiencing an issue like this:

  • My macbook battery will not charge. I have tried unplugging and doing an SMC reset but it did not seem to change. I have yet to try another magsafe charger. The charger has a dim green light while plugged into the computer. What are my next steps?

    Hello Everyone,
    This is my first time using the forum. My macbook battery will not charge. I have tried unplugging and doing an SMC reset but it did not seem to change. I have yet to try another magsafe charger. The charger has a dim green light while plugged into the computer. What should my next steps be, besides trying a new charger as well as being the most cost effective?
    Thanks

    Hi ..
    The battery may need replacing.
    Check the battery maximum cycle count > Mac notebooks: Determining battery cycle count
    And check the adapter >  Apple Portables: Troubleshooting MagSafe adapters

  • I work from my truck. I use my iPhone almost continuasly. Is it ok just to leave it plugged into the charger all day? So the battery is fully charged when I leave my truck.

    I work from my truck. I use my iPhone almost continuasly. Is it ok just to leave it plugged into the charger all day? So the battery is fully charged when I leave my truck.

    Yes. Charging automatically stops when your battery is full, & you can't overcharge.

  • Can I always operate my MacBook while plugged into an electrical outlet,  does this hurt the battery?

    Can I always operate my MacBook while plugged into an electrical outlet,  does this hurt the battery?

    Doing so does not hurt the battery. When remaining connected to a power source after the battery is fully charged, charging stops.
    It is recommended to go through one complete charge cycle at least once a month.

    Try:
    - Resetting the iPod:
    Reset iPod touch:  Press and hold the On/Off Sleep/Wake button and the Home
    button at the same time for at least ten seconds, until the Apple logo appears.
    - Resetting network settings: Setting>General>Reset>Reset Network Settings

    There is a hardware problem.  Whether it's worth it to you to have no working phone for 2 months until you can update vs paying for replacement/repair now is a question only you can answer.

  • I have an Retina display MacBook Pro with HMDI out port. I also have an HDMI to Component cable with Audio Plugs. How can I get HDMI out to work with this cable when plugged into the Component and Audio ports on my TV?

    I have an Retina display MacBook Pro with HMDI out port. I also have an HDMI to Component cable with Audio Plugs. How can I get HDMI out to work with this cable when plugged into the MacBook Pro and connected to the TVs Component and Audio in ports.

    Will not work.  To my knowledge, dual converting like that isn't supported.  The Mac must detect the connected video output device and that sort of info cannot be done across an analog component uni-directional connection.
