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.

Can you use a macbook while it is on charge?

You sure can! I don't recommend leaving it on the charger all the time though. Charge fully to 100%, unplug and run it until about 10% and then repeat the charging process. This will help the battery have a longer life. I've left for retina Macbook Pro unplugged for a week while working on school assignments between work and home and the battery is still at 30%.

how long does a battery last on a macbook (aluminium)
- Asked by Michelle S from Sudbury

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.

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.

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...

I believe so. I read that if you charge any electronic item too frequently without it being low on battery, it reduces its cycle. That is also what I have experienced with my many gadgets such as Blackberry, ipod touch, psp, laptops, etc.

Yes, this battery is a replacement for MacBook Pro model A1226 with battery model no. A1175.

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...

What is the warranty on this battery?
- Asked by Michelle G from Queenscliff
- Flag as inappropriate (What is the warranty on this battery?)
All new Apple products (those with an Apple logo, not just sold on their website/in their stores) come with a 1-year limited warranty. Any Apple Store can run a diagnostic in a few minutes to check on the health of your battery, but I'd recommend making an appointment when you go in.

Does this battery work with MBP model A1150?
- Asked by Polan F from Perth
- Flag as inappropriate (Does this battery work with MBP model A1150?)
Yes I think so. This is Battery' part number A1175. You can find your battery part number on your battery. Make sure that number is right and the batter is square in shape.

Will this battery fit in an earlier model of the Macbook Pro mid-2010 17 inch?
Battery Device # ASMB014
MACBOOK PRO bought in May 2010
- Asked by Diane C from Santa Cruz
- Flag as inappropriate (Will this battery fit in an earlier model of the Macbook Pro mid-2010 17 inch?)
Yes. I ordered one of these for my 2006 MacBook Pro 2.16 Ghz Intel Core Duo, and the one that came is exactly the same part (Model Number A1189, 10.8v, 68Wh) as the original battery that came with my MacBook Pro.
I believe this part is used for all 17-inch MacBook Pros, but if you want peace of mind before ordering, simply check the model details printed on the battery in your MacBook; if it says 'Model Number A1189' (as mentioned above), then it's definitely the same battery as the one advertised here.
