I remembered that they (iFixit, keep up) just did a breakdown and found the Surface Pro 3 to be unrepairable, for the layman at least (they even broke the screen in their teardown, which I've never seen happen before). I figured they might have a picture of the battery, which they did. They typed out the battery's watt hours in the article, but not its mAh. If they had it might have saved me a few minutes searching.
Actually, should I be looking at Wh or mAh to determine if a battery is better? I know there's a formula to convert them (using the voltage), but is one a better indicator than the other? I use mah because that's what I know, I guess.
Anyway, just posting this so someone further down the line can hopefully turn it up in a search.
