How to prolong MacBook Pro battery

Hi,
I have MacBook Pro Early 2011. And MacBook Pro already replaced the battery third times.
All of them are below 200 cycle count.
What is the recommendation to prolong battery life?
Should I keep it connected to AC?
Regularly run the battery down?
Thanks,

2. Absolutely NO, never (see below)
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is much more important on the wear and tear on your Macbook’s battery than the count of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less. Avoid this in all instances if you can. This is hard on your battery.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery).
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.
From Apple on batteries:
http://www.apple.com/batteries/notebooks.html
http://support.apple.com/kb/HT1446
"Apple does not recommend leaving your portable plugged in all the time."
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
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
*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.)
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%.
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.
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

Mid 2010 MacBook Pro battery capacity at 89% with 64 cycles

Hello everyone,
I have a 13" mid 2010 MacBook Pro that I got around Christmas time. I downloaded coconutbattery a couple days ago and when i used it then My battery capacity had been 91%. So I thought that this was odd because of how new the computer is still (15 wks old with 64 battery cycles) so I read about how the battery needs to be recalibrated from time to time and after doing so (followed the directions perfectly) My capacity is now down to 89%. Should this be something to be concerned about or is this normal?

It's quite normal and sometimes a recalibration can see things go up as well as down

MacBook Pro battery capacity dropped to 2%?!?!?!

Hi Everyone
I've recently noticed my battery capacity has dropped DRAMATICALLY in the past month. It's the 2.0GHz quad-core i7 15 inch MacBook Pro, early 2011 model. It is 15 months old, however I bought it brand new (box not even opened) from an eBay seller on 16th June 2011. I always keep it plugged in and very rarely take it off the charge, only if I want to go and work in another room but don't want to bring the adaptor. I know that's not technically good for the battery but it can hardly be *terrible* can it?
I've noticed that the battery was getting very low and after reading a forum post somewhere I downloaded coconutBattery. A few weeks ago, it read that my battery capacity was 68%, which to me sounded pretty low. Then about a week ago I looked again and it read 37% and I knew something was definitely wrong. I check today and it's dropped to 2%!!!!! I would certainly expect some loss of capacity but surely not this so quickly?
I use the laptop on a desk with "cool balls" underneath to lift it up and provide it with a bit of ventillation to keep it from getting to hot. The magsafe charger has a small tear just under the aluminium head which I covered with black insulation tape as soon as I saw it. Would this be the reason the battery is dying so quickly?
I'm thinking I'm going to have to buy a new battery at some point but I don't want to spend £100 on one if it's just going to happen again!
Thanks
ps. here's a screenshot of the coconutBattery window

Yes, you have to pay full price for it when purchsing it from Apple....
There are third party suppliers out there if you wish to buy cheaper ones but I'm not sure if they perform as good as the apple supplied battery...
good luck

<Edited by Host>

Either take the Mac in for service at an Apple Store or AASP and pay the full service charge that includes the labor. Or purchase an equivalent battery from any good online store and put it in yourself, all for substantially less. Apple won't sell you the part directly, only to authorized service providers.
Search with your Mac's model number in PowerBookMedic.com or IFixIt.com for the part as well as the how-to.

Depends on your particular model of MBP. It depends on the context, too. Do you mean hours of usage or do you mean life of the battery?

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
Affected batteries will have one or more of the following symptoms:
Battery is not recognized causing an “X” to appear in the battery icon in the Finder menu bar.
Battery will not charge when computer is plugged into AC power.
Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300.
Battery pack is visibly deformed.
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.

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.

How to Charge Macbook pro unibody? correct way

Hi there, I have a question. just bought my Macbook pro unibody last week.
I want to know how to charge Macbook pro the correct way ?
When im working. should I charge all the time ? I should wait until the battery drain 10% left ?
When is the best time to charge the battery 75%,50% or less that 10% ?
Should I turn off asap when the charger once the green light turn on ? should I leave overcharge ? normally I charged mac at night which more than 8 hour charge , is this good ?
Thanks guys.

Here is apple's instructions in calibrating the battery KB Article
As for leaving it plugged in, that's the normal process most people do, there is circuitry in the computer to ensure the battery does not get over charged. Aside from calibrating it, I'd avoid any deep cycles, that is draining it completely, you're better off plugging it in when you have the opportunity and not wait until the battery is nearly drained. Deep cycles can shorten the life span of the battery.

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.
