Keeping macbook battery plugged in

so you guys leave your macbook battery plugged in all the times(i.e. even when you go to sleep the light on the magsafe adapted is still green?) or do you unplug it when you go to sleep. and when you keep it plugged in do you remove the battery? im using my macbook at home, so its plugged it all the time to reduce battery charge cycles. but, i noticed that the battery still drains when the macbook battery is plugged in. the day before it was at 100%, then i unplugged it when i went to sleep, yesterday it was at 99%, did the same thing, and today its at 98%. i know that anything above a 95(?)% charged will not get the battery charged, so following this patter, my battery will prolly reach 95% 5 days later or so, and this will get the battery to start charging. my question is if i keep charging the battery at 95%-100%, will it decrease the battery life? and after 20 times of 95%-100% will it accumulate 1 charge cycle? if so, do i decrease the battery to 50% charge and then store it until i need to use the battery, so i doesnt keep on going through the above mentioned cycle.

This answers some of your questions.

All batteries have a self discharge rate even if they aren't being used. This accounts for the drop you see. I have mine plugged in 24/7 most of the time. I calibrate it every few months and once in a while I just run on batterys to let the electrons flow. Then when it gets below 90 % I let it charge. Short cycle charges are not bad for it. Most of the data says this is better than running your battery flat everytime you use it.

Keeping MacBook Pro plugged in.

New MacBook Pro 17'' owner here. Is there anything wrong with leaving the MacBook Pro plugged in to an electrical outlet with the USB cord? At the moment, mine is plugged in 24/7.

It should perhaps just be noted that the computer should be unplugged once in a while just to allow the battery to drain and "cycle". This will keep the battery in top condition in case you ever need it!
I'd recommend doing that maybe once every 3 weeks or so if you never, ever unplug the computer.

Macbook battery life, is there a problem If I keep it plugged almost all the time?

Hello.
New Mac user here, so I was wondering if there's a problem if I keep my MBP plugged all the time.
Most of the time I'm on my room using my MBP fully charged and I don't disconnect it.
Is there a problem with my batter life if I do that?
Or it's recommended to unplug and use it till the battery run off and then charge it again?
Because I work a lot on my MBP and that way in a simple day I could charge it and run uff the energy of the battery 2 to 3 times at day.
What's better for the life of my battery?
And if you could give me some advices to maintenance my battery and Macbook pro (also programs) I would appreciate it.
I own a Macbook Pro 13-inch, Mid 2012
2.9 GHz Intel Core i7
8 GB 1600 MHz DDR3
Intel HD Graphics 4000 1024 MB
With OS X 10.9
Thanks

No. I do that most of the time. Perhaps monthly I discharge it to the 40% level to keep the battery happy. Do not discharge the battery completely. If you are forced to use only battery power and you see the battery is low warning terminate your session or plug into AC if you can.
Here are Apple articles with official battery usage guidelines:

Does keeping a macbook pro plugged in even when fully charged damage the battery in any way?

Does keeping a macbook pro plugged in even when fully charged damage the battery?

no it will not, your battery stops charging when it reaches 100%. you can verify this if you'd like to through system report - power.
once in a while however, it's best to use it under it's own power and charge it back up once it's down to 75% to keep the battery in optimal condition.

My iPod mini, 4gb is hard to get serviced obviously because they dont make them anymore
It is as simple to get it serviced as the day you purchased it.
How is it hard to get it serviced?
How long have you had your iPod?
i get maybe 4-5 hours of battery life, maybe even 6 if im lucky
That is not good but it's not "terrible".
If you've had it less than a year, send it back to Apple to replace the battery.
thought that i might buy an attachment type accesorie that i plug into the usb port on my ipod
It's called a dock connector, not a USB port.
i found a product in the online store, that i guess you place the ipod mini on, and it gives you up to 20 or so more hours of time but then it says that you have to have a firewire port or cable?
What is it? The firewire port is on the computer, not the iPod.
If the original battery is going bad, the first thing to do is get that sorted out.

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.

Absolutely yes, it will ruin it.
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
From Apple on batteries:
http://support.apple.com/kb/HT1446
http://www.apple.com/batteries/
Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace

Keep Macbook Pro Charged or Use Battery?

I'm confused on whether or not to keep my Macbook Pro charged or use the battery from 100% until it reaches 0% and charge it again. I've read other posts and websites and they say I should keep it charged. I know you have to calibrate it, but I'm still confused on how the battery usage works. I currently have 63 loadcycles.

"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. "

HP Battery, Is It OK to keep the charger plugged in ?

Hi All
This is my first question here and I hope you'll help me
I want to ask if it is OK to keep the charger plugged in the laptop while the battery is full ?
I mean when the battery is 100%, will the energy go directly to the PC or it will go to the battery before ?
This question was solved.

Hi,
Nowadays batteries should be smart enough to stop getting charged when full. I can't see the difference from removing and keeping batteries on AC, some machines sit on docking stations all the times and some machines can be ON/OFF. This is my reply to another post:

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%.

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

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.

Is it good or bad for the battery to keep the powercord plug in after complete charge.

It does no harm. It won't over charge.

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.
