the new macbook pro 17 has a non removeable battery?

is it true?
so what if i dont really bring my macbook pro 17 around with me?
normally jus gonna put it in my house
if i 24/7 keep on using the adapter would the battery easily die?

 

yes, it has a non removable battery and no, you cant use it on adapter only as you cant remove the battery...go to the apple website for more info... www.apple.com

 

I believe it does affect battery but I cant remember here a link about batterys:

I've heard something about the battery being sucked out over a long period of time. Not insanely sucked out but over a while you might start to notice a couple of minutes decreasing. The battery becomes used to being stable constantly onto a charger that if its never pulled out it'll have trouble giving you the amount promised.

Typical lithium ion or NiMH (nickel metal hydride) batteries last longest (that is, accept the greatest number of full charges before displaying diminished charge retention) if not stored in your laptop when it's plugged into a wall socket. You can achieve optimal battery life by storing the battery at temperatures between 35 and 45 degrees Fahrenheit (typical refrigerator temperatures) at a 40-percent charge level. Before you take the laptop PC on the road, charge the battery up to 100 percent. When you return to your home or office, discharge it until the level reads 40 percent, and then place it in a waterproof bag and put it back into the refrigerator.

Old NiCad (nickel-cadmium) and NiMH (nickel metal hydride) batteries, popular in the 1980s and 1990s, had bad "memory" properties: they would "remember" how they were charged. For example, if charged to only 20% of capacity, then used, they would last only 20% of their rating. If left in the laptop continually whilst connected to the mains (AC), they would not last more than a few minutes once unplugged from the mains.

Luckily, we now have Lithium Ion batteries which last longer and suffer far less from memory effect. Discharging and charging does not increase the life of a good quality Lithium Ion technology battery and is designed to stop using the charger when it reaches full charge. All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. Spend the extra $ and buy a new laptop battery /from the manufacturer of your laptop/ when the run time does not meet your needs. Cheaper, no-name batteries may not have the "smart" technology that the batteries shipped with your laptop did as spec'd from the manufacturer.

More battery power means more battery life
When you purchase any laptop PC, you often have the option to purchase a more powerful battery than the one included with the unit. Many laptop PCs ship with a 4- or 6-cell battery that you can upgrade to 6- or 9-cell version for an additional charge.

Hualsay, the new Macbooks use Li-polymer batteries.

 

For the love of god.

holy cow, did you really have to create a whole new thread when its stated on apple's website or 2 seconds on google would do it?

 

i just want to know
if the battery is non removeable therefore if i normally use my laptop liek a desktop , i would use the adapter most of the time , does that mean that my battery will be always charge ? and will that easily make the battery die?

 

Learn how to use either the SEARCH function here, or Google. Both will provide you with answers to your questions.

 

Or just give him the answer...

The battery will stop charging when it is full or nearly full to prevent constant charging. I do not know how the 17" Unibody is but for for the MacBook Unibody the battery is easily removable. Just a screw. However you will not be able to do it on the road etc (or rather you wont want to). I do not think MacBooks Pros can run without the battery anyway at least not at full speed.

 

To my knowledge and recall, the aluminum 17" does not have a removeable back to access the battery or other internals, i.e. the 15" and 13" models. It is accessible only to Apple technicians or someone with a lot of tools, but you are unlikely to be able to purchase a new Li-polymer replacement anyway.

 

The current unibody lineup doesn't work at full-speed because the CPU may at times need some extra power from the battery. Therefore, to prevent issues, it works at like 40% speed maximum when plugged in without a battery.

 

this is not true. the difference is only ~10% (closer to 7%, but i don't know the exact value). the 40% decrease in performance was hyped up by some website. one of our forum members debunked the myth with his own benchmarks. besides, you said it works at 40% max, which is a 60% decrease in speed... which is also not true.

To answer the OPs question: no, you will not notice an appreciable change in battery life by leaving it in. battery technology has advanced far enough to where this isn't an issue. that is, of course, assuming that you're not worried about losing a few minutes over the course of the lifetime of your battery (compared to those people who religiously remove their battery).

 

Apologies for the mistake.

 

no worries. here is the thread: http://forum.notebookreview.com/showthread.php?t=330805

 

Or teach him how to find his own answers which are already out there....

 

bascially when its full it will stop but the battery still cant be removeable? will be contastly on macbook pro

 

If you don't want to answer something just ignore it. No need to waste your own time telling others off.

 

Who says I'm wasting my time?

 

That is correct. The system will then disengage the charging circuit to allow the battery to discharge a bit, and then will recharge it. However, the system will also individually monitor all of the battery cells and charge only those that need it.

You should head over to the Apple website to read more about how this new technology is supposed to work - they have a nice discussion there in the 17" MBP section.

 

I just did

 

ZOMG a link! From Apple! No wai! http://www.apple.com/ca/macbookpro/features-17inch.html

 

Whew! I thought it was someone important at first!

 

Because the search function sucks, It has yet to return any usefull information in my searchs.

If you can't provide a useful information, maybe you shouldn't bother to reply.

 

He is gonna tell you to use Google

 

http://letmegooglethatforyou.com/?q=lithium-polymer+notebook+battery

 

So what happens when 2 year down the line the battery dies ?
Is it user serviceable ?

Does the 3 year applecare cover the bateery in the 17 MBP ?

 

The new battery in the 17" Aluminum MBP is not user-serviceable. Typical industry warranty, including Apple, for batteries in any notebook is 12 months from purchase. AppleCare does not cover battery replacement, and I believe might even specifically exclude it.

Whether Apple decides, with the new technology of the Li-polymer they're using having anticipated higher cycle numbers, to extend this is unclear at this point - at least, I don't recall seeing any details discussing this anywhere.

 

I think it's around $170 to get the battery replace. Witch is not bad.

 

Thanks

Do you know how difficult it would be to replace the battery (even though its not supposed to be user replaceable) ?
Is it likely that there will be third party batteries ?

 

Including hardware and service costs for the 17" MBP ?

Yes, thats not bad

 

Ohh right , thanks.
