    Hey I'm looking for the capacity of the 1179$ cdn 13-inch MacBook Pro in mAh
    I chatted online, searched and called Apple, and none of them know, pretty brutal for the worlds largest company.

    Follow up, how much more would you get out of similar lithium batteries if one had a capacity of 4000 mAh, while the oterh had 5000mAh?

    Except it's not the world's largest company. :rolleyes:

    The 2012 15" models have a 10.95 V battery, so it's probable that 13" models have the same. Simple multiplication gives you an estimate of the capacity:

    Q (mAh) = Q (wh) * 1000 / V = 63.5 * 1000 / 10.95 = ~5800 mAh

    It was on the stock exchange pretty recently.

    I forgot I had a friend who works at the mac store XD

    It's 5020mAh.

    So will a 5000 mAh, last 25%ish longer than a 4000mAh charge? Or is it diminishing returns?

    It has the largest market capitalization. It's not the largest company.
    There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.

    This should answer most, if not all, of your battery/charging questions:

    It's right here in Watt-hours:

    http://www.apple.com/macbook-pro/specs/13-and-15-inch/

    Why do you need it in mAh?

    A 5000mAh battery would last ~25% longer than a 4000mAh battery. This is only if they're both under the exact same load, but it doesn't really matter because there aren't different capacity batteries for any given model of MacBook Pro(i.e. all current 13" units use the same battery).

    You know what I mean, its silly for a company in this day and age not to have all their product specs made public, or that their phone tech support doesn't even know it.

    the 63.5 watt-hour is the pour it uses, not the capacity which is in mAh.

    I wanted to know because I was looking at a Sony VAIO that seemed identical to the 13 inch macbook pro. Only differences are that the VAIO has an HDMI and GVA outpout, but 4000mAh battery.

    I was wondering how much better the 5020mAh would be. Somehow I doubt the mac would lat 25% longer, but I could be wrong.

    The specs are there, just not in the format you're looking for. If you can find out the voltage of the MacBook battery, you could figure out the equivalant mAh rating.

    http://www.rapidtables.com/convert/electric/wh-to-mah.htm

    They're both measurements of power stored in the battery, just so you know.

    ----------

    iFixit lists the battery for the 2011 13" MacBook pro as a 63.5 Watt-hour unit, and they also list it as a 5800mAh battery.

    One thing you need to keep in mind comparing these two laptops is that they're running very different software. So even if they both have similar hardware specs, the software plays a major part in battery usage.

    To compare the two laptops, I'd suggest searching to see what kind of battery life users are reporting for both. As far as I know, Apple posts pretty accurate estimates on their specs pages. I don't know about Sony.

    It should not be up the consumer to do the research calculations, all the information should be readily available on their website.

    Nobody cares about the difference between watt-hours and milli-amp hours. The website provides more than enough information for the vast majority of people.

    I guess some people want to know how long their battery will last, not how powerful it is. No product ever lasts the suggested hours they put on their site.

    If that is the case, why doesn't Sony provide the rating in Watt-hours? It's not like there is a standard set for this, requiring companies to list a specific set of specs. If you're having issues because you can't compare the specs of the two batteries, Sony is just as at fault here as Apple.

    If this upsets you, don't flip out at us. Send an email to both companies complaining that you don't like the way that they list their product specs.

    ----------

    Apple lists a up to 7 hour "wireless web" battery life, several reviews I've read have confirmed this is correct under light use.

    Like I said, I don't know if Sony lists their battery life as accurately.

    Not really sure what you even mean by that. "Powerful" isn't really a good adjective to use when describing a battery.
