Lithium Polymer: 46% More Capacity, 0% More Weight

Today Apple is shipping lithium polymer batteries in all of its MacBook Pros. Only the original, white MacBook is offered with a removable battery. Most impressive are the capacities Apple is able to offer thanks to these new batteries.

The table below shows the old and new battery capacities:

  New Lithium Polymer Battery (Integrated)

Old Lithium Ion Battery (Removable)

Increase in Capacity
MacBook Pro 13-inch 58WHr 45WHr 29%
MacBook Pro 15-inch 73WHr 50WHr 46%
MacBook Pro 17-inch 95WHr 68WHr 40%

 

Now there was no 13” MacBook Pro before, so I’m comparing to the old aluminum 13” MacBook. Also, the 17” MacBook Pro was the first and only unibody 17” MacBook Pro so the old battery I’m comparing it to was the previous generation 17” MBP battery.


73Whr?!? Holy crap

The biggest winner is the 15” MacBook Pro, it gains a 46% increase in battery capacity with zero increase in size or weight. The new 15” MacBook Pro is the same size and weight (5.5lbs) as the previous model, it just has a 46% larger battery. Did I mention it’s cheaper too?

    My university store sells Apple computers at the discounted price to anyone who walks in. Likewise, I've ordered discounted stuff at an Apple store simply by saying (truthfully in my case) that I work at a university; they never asked for credentials.

    BTW, you qualify if anyone in your family attends (or works at a) school at any level.

    I've red about 5 reviews of the new macbook pros honestlly curoious if the 7 hours battery claim is true. Most other sites did a comparison with the older mbp's and seems the new one dont last more than 1 hour over those, so unless the old ones lasted 6 hours (which i really doubt it) then this is a big lie. On the other hand squeezing 6-7 hours out of the battery by browsing 1 page per hour with dimmed brigthness on a screen which is already amongst the glossyest is again highly unrealistic.
    On the other hand the new Lenova T400 is a 14.1 inch machine, with decentlly powerful configuration, which is lighter then the 15 inch mbp, and lasts 6 hours with the regular battery and 9+ with the enhanced one, this with a high brightness setting that makes the screen readable, and actual internet work beeing done on it. I know this because i have one, and i did a test (now that I also got by 9 cell battery).
    I'm not saying that the t400 is better than mbp, just that for all of Apple's claims of how inovative their battery is, it doesn't really look like it once you actually go beyond the bla and actually test it. On the other hand the battery is very much non removable which is really a big downer.

    Upgraded my macbook 13" 2.4GHz to the 2.53GHz version.

    After the first full charge, using the laptop quite intensively (re-installed the system, copying files across etc); I got 3 hours and 20 minutes.

    After the initial full cycle. The 2nd time, very ligh usage. Only using a text editor, an ssh connection opened in terminal and web browser sitting.
    I got 4 hours and 30 minutes when for the last hour the laptop just sat there doing nothing with the screen off (I turned off the screen saver).

    I would assume that the 15" MBP doesn't use that much more power than the 13" as the hardware is almost identical and being a LED backlight LCD, the screen isn't going to use that much more.

    The 15" has a significantly bigger battery, yet Apple advertises both the 15 and the 13" to be 7 hours...

    I wouldn't mind running the same test Anand did for the 15" and see how much I get..
    Because 4.5 hours is a long way away from 7 hours

    I guess I shouldn't be surprised considering I've been around the Apple scene for a while, but there is nothing "Pro" about the Macbook Pro laptops other than the FW800 which was brought back to the 13" which is a nice touch -- especially considering that there is no eSATA support so you were stuck with USB for external drives (ouch).

    Of course, I'm not denying the fact that Apple has incredible hardware engineering talent and beautiful, well-built machines. And the matter of OSX is self-evident.
    I've always had a love/hate with Apple. One half of me loves to geek out on hardware specs and wants only the best processor, GPU, highest quality display, and all the features like SSDs, eSATA ports, firewire, expresscard, memory card reader, etc --- And all for the best price.
    The other half is more aesthetically inclined, and greatly admires the beautiful hardware and software of Mac laptops, and doesn't worry so much about bang/buck and having the best specs --- It realizes the overall experience is far more important than benchmarks and always having the best.

    I think I could compromise on a 15" or 13" Macbook Pro if only Apple would put at the least the option of a high-quality, full-gamut, high-resolution display along with a decent Nvidia Quadro card. But I'm sure it will never happen...

    An apple laptop is basically an expensive BIC pen for rich people...

    If you know anything about computers, you basically DONT buy a mac for that reason. Its made specifically for stupid people, and there are more of those in the world then the smart ones.

    My Thinkpad, for example has 10500 mAH AND the battery is REPLACEABLE.

    Where plastic macbooks have cracked and cheezy aluminum macbooks have dented, and the new ones have cracked glass screens, my T series has survived all 4 years of college.

    The Thinkpads were always environmentally friendly. In fact, IBM was pretty much always on top and Apple on the very bottom of that scale. Only recently did Apple start to become green.

    I run an IT department which supports Macs and PCs and my experience doesn't line up with your assertions.

    Cracks developing in the front edge of the plastic shell is a well-known design flaw with early MacBooks; when this happened (in the instances that I'm familiar with), Apple replaced the case with newer ones that don't crack. We have several aluminum models in house and only one has a dent. It's minor, was due to something heavy being dropped on it, and doesn't affect functionality so I consider it a non-issue.

    Some of Apple's stuff is reasonably reasonably priced and some of it isn't (just like Dell, Lenovo, Sony, etc). The difference is that Apple doesn't sell low-end hardware.

    Pretty much everyone qualifies for the educational price ($1099 for the 13" MacBook Pro) and you get a free-after-rebate iPod touch and printer. The 8GB iPod touch is actually an effective and reasonably priced PDA/media player, but if you don't need it or the printer, you can sell them on craigslist/Ebay for $180 + $50 bringing the effective price of the 13" MacBook Pro to $870 (or do the same with the MacBook and it goes down to $720).

    A slim, lightweight, metal Windows laptop with a quality-LED screen, fast CPU, and long battery life is likely to cost that much or more (especially if you get it with XP Pro or Vista Business). Now add in FW800, the maglock power connector, multitouch pad, and backlit keyboard and the base 13" MacBook Pro is actually a decent deal.

    Obviously, it depends on what your computing needs are as you can certainly find a cheap Vista-home laptop without some of those features for significantly less money.

    You are stupid yourself if you call people like Anand stupid. Reply

    I dunno where you guys get these outrageous 10+ hour battery life figures from. My Thinkpad T60 with the 9 cell (6 months old) gets no where close to 10 hours. I doubt you guys are getting the type of endurance you claim from T43s and the Sony TX's. 18 hours on the TX with extended battery? Come on... Time it. Reply

    ever care to mention the macbook air which got a $700 price drop? ANANDTECH FAIL. Reply
  • Anand Lal Shimpi - Sunday, June 14, 2009 - link

    You are correct, the MBA received a huge price drop which was very nice. It slipped out of the article since it didn't have any major hardware upgrades, although I still love the MBA for a writer's companion.

    Take care,
    Anand
