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 DM from Millville

Best Answer
I would have to disagree with the others who say that it hurts your battery & reduces battery life by keeping your AC adapter plugged in with a full battery.
I have done extensive research and asked many apple employees and have always come to the same conclusion. They all say to keep your laptop plugged into an power supply whenever possible. Only use your battery if you have to, in those times when you are not near a power supply.
Every time you use your batteries power you are adding to the amount of cycles your battery can cycle. If you continually charge your battery to 100% and then take it off the AC Power, and use it all the way down to 0% or even 50% you are taking away from the batteries lifespan. And eventually your battery will not be able to hold a full charge, and eventually will not hold a charge at all, and you will have to buy a new one!
Use your AC Power as much as you can, but remember to calibrate your battery at least once a month to maintain proper battery health.
To calibrate your battery:
In Finder, Click Help and type in: "calibrate battery"
Then select: "Calibrating a portable computer battery" Help Topic
Follow instructions.
Hope this helps ease your mind and keeps you with a healthy battery! Cheers! …More- Answered by SO from Lockhart

is this the A1175?
- Asked by TH from Medstead
- 07-Oct-2009
Best Answer
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... …More- Answered by YP from Chicago

Yes I think this is the one. At the bottom of battery you should find battery model number. If I am not wrong then it will be A1175. Any battery that replaces A1175 will be suitable for your laptop. Tech Specs should include 10.8V Capacity: 5800 mAh 6 Cell Color: Silver Battery Type: Li-Polymer. …More

What is the warranty on a replacement battery?
- Asked by CK from Tampa
- 09-Oct-2009
Best Answer
Apple’s standard for battery deterioration is that the battery should hold at least 80% of it’s maximum charge capacity after 300 cycles. Under normal circumstances, this means roughly 2 years. Granted, everyone has a different definition of normal usage but Apple usually won’t deal with a battery if it’s been through over 300 cycles or three years or age. …More
