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?

    Right now, you may not care that your battery isn't removable. After 13 months, when it's failed and Apple want to charge you the price of a netbook to take it in and replace it, you may do. Reply

    It's been done already long before Apple (as with most of their innovations) plenty of companies have produced laptops with extremely long batterylife but without fixing the battery.

    Apple's solution is nothing clever as all they've done is sacrifice the removeable battery, I just really hope other companies don't do this as well as has been happening in the mp3 player market particularly with Sandisk.

    From an environmental standpoint, having battery built in means you will have to bring the Notebook back to Apple to buy a new battery. This would means your old battery is properly deposited.

    I am surely there will be third party, or possibly even apple would make an External battery for all Macbook that plugs into the power plug.

    Those products (external batteries) are available from different companies already... Reply

    Yup, they've been around for ages, though I'd say Apple have energised the market for them:

    Now it has been proven that there are massive amount of external power out there. I wonder why the need for a removable 2nd battery?
    With Internal battery, you get more space, longer battery, and more environmental friendly. Why would you need a 2nd battery when you can do the same with external power?

    That is an interesting thought. Wonder how feasible it is... Reply

    I'm looking at the specs and can't help but think Apple moved the 13" unibody MB into their MBP line and added a price cut to boot. My wife just got a "free" 13" unibody. (Her MB was a legit lemon, and after 5 or 6 Applecare repairs, the store just gave her a replacement) Anyway, the specs of her replacement are in line with what I see here for the MBP version. We don't have the machine with us to compare removable batteries, but we'll definitely do that after our honeymoon. Reply

    For a truly portable machine for getting stuff done, wouldn't an 11" netbook be a better option than a MacBook?

    Right now I don't think any of the MacBooks stack up as well as machines like the Acer Aspire 11.6".

    11-12 inch netbooks seems to; tick all my must haves (see below), have excellent weight, and great form factor. While I would prefer an OS-X machine, MacBooks that meet my must haves are twice the weight and 4 times the price of a comparable netbook.


    For my needs at university. I've settled on the following requirements:

    Absolute must haves are:

    - Display sufficient to view and skim read multi-column research papers:
    >= 1200x800
    >= 11"
    - Suffient performance to:
    - quickly flick thourgh PDFs and powerpoints
    - create and edit files using MS Office
    - surf the web
    - >= 8 hours battery for the functions above
    - fullsize laptop keyboard
    - OS-X or Windows (no Linux due to MS Office:-( )
    - WiFi, tackpad, >=20Gb free disk, USB, speakers.

    In addition, my nice to haves are:
    - OS-X over Windows
    - Light
    - Thin
    - Low price

    Snow Leopard were suppose to speed things up, May be it will bring some even greater battery life. May be a retest once SL is out?

    I can imagine future Macbook Pro having 12 hours battery life if it has an SSD and OLED display.

    Apple could surely make an interesting Netbook or Cheaper Macbook Air with Dual Core Atom with these Battery inside.
