Wondering, if you don't need mobility of battery power; should you run off AC or Battery power; which is better??

This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ

You can do it like you want, just remember to calibrate once in a while (every month) and use a search engine like MRoogle.

to get the most out of your battery life, you should run it on battery power most of the time and recharge in between per Apple. you should also calibrate the battery at least once a month.

Is it better to let it charge without using it; or does it really not matter????

Read the Battery FAQ link that simsaladimbamba posted. It clearly answers all your questions.

you can let it charge without using it, but don't treat it like a desktop and keep it plugged in all the time. it'll diminish the battery very fast.

Not really true. I have a 17" MBP with 12xxx mAh and the first year I almost exclusively used it on AC power. The last year (year year) I used it more and more on battery power and still have 98% health and get four to seven hours of battery life depending on what I do.

It does not matter. Again, read the FAQ I linked to.

Read step 6 in the calibration procedure in the Battery FAQ.

well i went through my 1st battery within a year after doing my best to follow the apple procedures and went through my 2nd one almost a year after that. i called AppleCare and was told if it's kept plugged in most of the time you will not get the life you expect from it. MBP's were designed to be used as mobile devices (like using it on a train on the way to work) and then plugging it up once you're at the office. their scenario. i have done it both ways and neither really work too well. i guess if you don't plan on going mobile with it then it really doesn't matter. i do know MBP batteries suck as far as life goes.

It's true you shouldn't leave it plugged in 24/7, but you also don't need to run it on battery most of the time, either. Read the Battery FAQ for proper use that will maximize the life of your battery.

i have read it. you really don't need to post that 2 or 3 times.

Take it to Apple to get it replaced, if you're still under AppleCare. It's toast and obviously defective.

If you've read it, then why do you continue to post inaccurate statements?

Not true at all.

You can, but as the FAQ shows, you can use it while recharging.

Appreciate your help; I did previously read that posting, but I never put much faith in a manufacturer's recommendations... I would rather talk to people and get their first hand experiences...

Apple replaced the first one, they won't replace this one.

Where do you get all your info from? Just because you post it does not mean it's the truth. Your AC recommendations contradict what Applecare told me on the telephone. So please link your sources, unless you are the source. No need to start a pissing contest, but I have run my mac using the recommended procedures from Apples site and it still died.

They are going to vary as you can see. There is no one way to do anything. I say use it however you need to and see what the results are. Good luck!

VBulletin (the forum software used here) allows for normal length links like these: http://www.apple.com/batteries/notebooks.html
Anyway, the link is included in the FAQ by GGJstudios (though not many seem to read it) and the more descriptive article about properly calibrating the battery has also been posted already.

All the information in the Battery FAQ comes directly from Apple. It's filled with direct links to and quotes from Apple's site. It's entirely possible that an individual at a Genius bar or on telephone support can be misinformed, but Apple won't publish misinformation.

People aren't going to replace your battery if it's defective. Apple will. If you follow their recommendations and your battery fails, you can hold them accountable. If you follow someone else's recommendations and your battery fails, Apple can claim the failure is because you didn't follow their recommendations. If you put faith in Apple to build the battery and your Mac, why not have faith in their instructions on how to properly use and care for them? They know better how to care for your Mac than any stranger in a forum.
