how long does a battery last on a macbook (aluminium)

Realistically this battery will last around 3 hours as long as there is not heavy usage of the CPU or GPU. So as long as you are doing basic things like e-mail, web surfing, etc you should get decent life out of it. Also turning down brightness, running only 1 program at a time, and turning off bluetooth will all help preserve battery life. Also running it in cycles and using a battery keeper program will help to extend the life. I am a photographer and if I am doing light photo editing I can pull 2-4 hours out of this battery as long as I adhere to the aforementioned guidelines.

charging battery for the first time
How long does the battery needs to be charged for the first time on macbook pro 15.

Just plug in your ac adapter and use the computer. Ensure the battery if fully charged before using it on battery power and let it drain all the way down before the next charge. From then on, use the battery about once a week till it is all the way down and you are getting those "Save your work now" messages" and let it charge all the way up again. You can use the computer while it is charging. All of this is from the a recent Genius Bar appointment where they told me my battery was failing for lack of use and that it had a very low number of cycles on it and that was not good for it.

Can you use a macbook while it is on charge?
- Asked by Hayley G from Brisbane
- Flag as inappropriate (Can you use a macbook while it is on charge?)
Of course you can. It is recommended however, that you take the Macbook off the charger as soon as it reaches a full charge so as not to shorten the life of your battery. Leaving it plugged in constantly can actually damage the battery long term.

Does it harm the battery or reduce battery life, to use the AC adaptor for extended periods while the battery is fully charged?
- Asked by David M from Millville
- Flag as inappropriate (Does it harm the battery or reduce battery life, to use the AC adaptor for extended periods while the battery is fully charged?)
I have experienced the same thing, but the question remains: WHAT IS BEST TO DO INSTEAD? Leave the MBP unplugged every time the battery gets fully charged... then only plug it in when the battery is low, recharge it, and unplug it agin? Take the battery out if the MBP is to be plugged in for long periods? Do some internet research on voodoo rituals that might help battery life? Anyone have a practical suggestion on the best battery-sustaining habits to get into?
Thanks to all...

Can I still find a battery for model number A1175?
battery model #A1175
- Asked by Jeffrey H from Corrales
- Flag as inappropriate (Can I still find a battery for model number A1175?)
To calibrate the battery:
Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
Disconnect the power adapter with the computer on and start using it with battery power. When the battery’s charge gets low, you’ll see the low battery warning dialog on the screen.
Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery’s charge gets low and before the computer goes to sleep.
Turn off the computer or allow it to sleep for five hours or longer.
Reconnect thepower adapter and leave it connected until the battery is fully charged. You may use your computer during this time.

This battery could be the one you need, shutdown or hibernate your Mac, remove the battery and on the "inside" pretty much dead center will be the "Model No.". If this is your battery, the model number should be A1175.

Is this battery compatible with the 2009 17-inch macbook pro?

I found below opinion from other apple forum. It might help you.
MA348LL/A and A1175 are the same thing. MA348LL/A is the Apple part number (aka order number), A1175 is the Model Number of the battery. So, if you order MA348LL/A and actually look at the printing on the battery, you'll see Model A1175 on there.
If you're referring to the batteries available on Amazon, check one of the reviews for the less expensive A1175 item:
When they say 'original' Apple laptop battery they mean that literally. The battery I received had a serial number ending in U7SB - one of the orginal MacBook Pro battery packs manufactured between February 2006 and May 2006. These batteries were found to be defective and are subject to an Apple product recall. Fortunately, with some persuasion, I was able to convince the local Apple store to exchange the battery pack for an updated one. The Apple battery recall website will not validate you for an exchange unless you have a MacBook Pro with an early serial number.
One of the risks of buying batteries from 3rd party vendors is getting old stock. For some things (e.g. a power adapter) that's not much of an issue. But lithium-based batteries have a useful life of 400-500 charge cycles or 3-4 years - whichever comes first. Shelf life counts against that time - there's a continuous chemical reaction occurring in the battery, and buildup of oxidation products - and the latter is actually worse if the battery is not being used. So, if you buy a battery that was made 2 years ago, you can expect to get 1-2 years of use from it (probably closer to 1), not 3-4.
My advice - get the more expensive one, or even pay the extra $10 and buy direct from Apple (it's not necessarily $10 more, since Apple offers free shipping and the 3d party vendors on Amazon who charge less than Apple may charge for shipping).
Hope this helps...

No, the A1185 battery is very different in size and shape and will not work. The A1189 fits the 17 inch MacBook Pro while the A1185 fits older MacBook 13

Are the new long life batteries compatible with a late '08 macbook pro 15
Are the new long life batteries compatible or interchangeable with a late '08 macbook pro 15" when replacement is needed?
- Asked by William M from Tendoy
- Flag as inappropriate (Are the new long life batteries compatible with a late '08 macbook pro 15)
First question is will this fit in MBP 15" late 2008 model? Second question is how long this battery will last in normal usage on this model?
I do have MBP 15" late 2008 model. Will this battery fit in to it?
Currently battery is in good condition (100 cycles - 4200mAh charge). But this last for around 2hrs approximately. Is this what apple batteries last normally?
Apple writes in the product details that MBP 15" latest models can have appro 8-9 hrs of battery life! Is this true or a trap?Best Answer:
This battery will fit any 15-inch MacBook Pro with a removable battery. Your model is supported.
Normal usage is supposed to be around 4 hours, but actual usage may vary. Most users report an average battery life of 2 to 3 hours, but if you cycle your battery as apple recommends, you may have a better experience.
The latest MacBook Pros are unibody models, which means that their batteries cannot be replaced. This battery is for the older models, such as the one you have, which only support approximately 4 hours of battery life.
