Is keeping the your macbook plugged in while battery charged ok?

Is it harmful to your macbooks overall battery life if you keep it plugged in if the battery is fully charged?

It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate. You should calibrate your battery once a month. Li-Ion batteries prefer small charges so anytime you want to charge is fine.
The following links have good information about the MacBook and the care of it's battery.

  • Can I keep the power cord plugged in when battery reaches 100%l?

    Hello,
    I'm assuming the battery stops recharging when it reaches 100%, right? In other words I can keep the power chord plugged in without any risk of "overcharging". Correct?
    Thanks.

    Helpful, thanks. FYI, 2 Apple agents at Mac support have advised otherwise (said I have to remove the cord).
    How bizarre....I have a 2.5 year old MacBook that gets great battery life (~4hrs) and begs to differ. Anyway, Thanks for the Star!

  • Keep the broadband hub plugged in and on all the t...

    The subject is my question, do I keep the broadband hub plugged in and turned on all the time... apart of course  when I go on holiday I shall turn if off and unplug it. whilst I am home I am presuming I leave it on all the time??
    I have looked for an answer to my problem but couldn't find anything.. maybe its a dumb question... I have never had broad band before, I had a dongle and left it on most of the time.
    I have limited data, 10gb per month.
    Solved!
    Go to Solution.

    It's recommended that you leave it on.
    Turning it on and off too often looks like a faulty line so far as the exchange (or cabinet for Infinity) is concerned, and that could drop your broadband speed.  However, just turning it off at night wouldn't be a problem.
    If your speed ever drops because of a spate of interference, for instance in a big storm, then it's best to leave it on all the time, including overnight.  That way the exchange sees a nice stable connection for several days, and bumps the speed back up to what it should be.
    Turning the Hub off when you go on holiday is fine, unless something (such as BT TV) is going to need it.

  • Which wire on the 30-pin plug is responsible for charging an Ipod?

    I just cut wire #23. It does not charge it now but the ipod is not recognized either. Would adding a false drain on the 5 volts help? I don't know what else to do. Let me know.
    Yes.  Reconnect the wire and use the iPod the way that it was designed to be used.

    I see no reason why it shouldn't. At prices I've seen down to $4.39, I wouldn't hesitate to give it a try. That's cheaper than a sandwich!

  • Leaving the Macbook plugged in w/battery out. Is it safe?

    I typically use my macbook on my external hdtv so i keep it plugged up with the battery removed. Is this safe to do or should i always unplug it when i'm not useing it.
    it just a hassle to plug it up everytime i want to use it. And i took the battery out because i'm not using it in the traditional method.
    Should i be concerned if i leave it plugged up? Will this do any harm?
    thanks

    Safe? Well, it won't harm the computer, but if you have important files on the computer, you're putting them at risk. If the power is lost - if there's a power outage, brownout, or you accidentally pull the power cord out, you're shutting the computer down in a very "harsh" manner - essentially crashing it - so your hard drive would undergo undue stress and wouldn't get the safe shutdown it requires to help safeguard your files.
    I highly recommend you keep the battery in. If you're permanently connecting it to the mains - which is fine - the battery isn't going to run down, so you're not wearing it out by having it connected.

  • Meaning of the wall-plug icon while in charger

    Hello !
    When I charge my iPhone it first has the lightning bolt while charging, then switches to the wall plug icon when its charged. When I leave it this way, the battery depletes slowly just as my macbook does until it reaches about 93% then the lightning bolt is displayed again indicating its again charging to 100%.
    Ok so here is my question: When its finished charging and the wallplug icon is shown, does the iPhone still get some "small" charging current to slow down battery depletion or nothing at all? Or in other words: Does it make a difference when I take the phone off the charger as soon as the wall plug is shown compared to leaving it in the dock?
    Kind regards,
    Sascha

    OK, please let me rephrase what you said (this helps me to check if I understood ):
    The lightning bolt changes to the wall plug when charging of the battery is complete. At this time, the battery is internally disconnected from the phone and the charger.
    From this point on the operation of the phone is entirely maintained by the charger as the battery is not "connected".
    Even while the battery is not connected it will slowly deplete due to internal leakages and other chemical processes.
    As soon as these internal leakages drop the battery level under a certain percentage, the phone connects the charger again to the battery and charges it back to 100%, then disconnects the charger again.
    When the charger is disconnected from the phone, the phone connects itself again to the battery to power the phones normal operation by the battery.
    Right?
    Correct me if I am wrong, but this means, that it is totally harmless for the battery if the phone is left in the charger, as the battery is only charged when the internal processes dropped the charge level under about 95% which does not occur often, and in the meantime the phone is powered by the charger.
    By the way, when left in the charger my 4S needs about 2 days to drop low enough to be recharged, thats about 93%.

  • Should I keep the iPad 2 plugged in whenever I can?

    I have seen many discussions regarding Lithium-Ion batteries but am not yet sure whether I should keep my new iPad 2 plugged in to the power outlet whenever I can conveniently do so?  As long as I deplete the battery completely once a month as suggested at http://www.apple.com/batteries/ipad.html, having the power adapater plugged in would reduce the overall number of charge cycles and thereby enhance the life of the battery, or?
    Would it be better to unplug it when it is fully charged in order to not overheat/overcharge the iPad?
    Thanks for any advice!
    Nancy

    The best maintenance for any battery is to use it as much as possible.  Charge it when the battery gets low (turns red).  I let mine go as low as possible considering my circumstances (when I'm just sitting at home is one thing, when I'm on the go, it's another).
    Batteries (no matter the technologly behind them), do best when the battery is used like it's supposed to - use until it needs charging, then charge to full charge.  Leaving the charger on there causes no risk - it can't overcharge and shouldn't ever overheat.  BUT - don't leave your iPad charging ALL THE TIME.  It's best way to have a battery that won't hold it's charge when you need it to.
    I've seen all too many folks who've had laptops, keeping them plugged in all the time, then wonder why when they do use the battery, it no longer works.  I hear the same thing:  "I haven't even used the battery!". 
    Just remember, batteries are meant to be USED...so let them do their job.  Charge/Discharge/Charge....and so on.
    Cheers!

  • How do I keep the internet access plug in on?

    When I download Adobe Reader and restart my computer the internet access plug in is loaded but as soon as I go onto the internet through firefox it turns those plug ins off. How so I keep them on?

    Firefox has its own PDF Viewer built in, so you need to disable it.

  • Is it safe to use the new ipad (3rd gen) while on charge

    I have the New Ipad (3rd Gen) 32gb wifi onlymodel,, and I use it while on charge i notice that it took way longer to charge while i use... will in not damage the devoce nor the batter if i use it while on charge?

    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.

  • 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.

  • Should I keep my macbook plugged or let battery drain then recharge?

    I just got 1st MBP and wanted to know whats best? Let battery drain to 15%- 20% then recharge to full...or.... when near a wall unit, keep it plugged in?

    It makes no real difference although if you are near a wall outlet it makes sense to run from the AC adaptor. However, if you always run from the AC adaptor then periodically you want to use the battery so it is in use or once every couple of months do this: Apple Portables- Calibrating your computer's battery for best performance.
