    Can anyone tell me the capacity of the battery in the MBP 2010 15" model? I'm on my third battery right now (this time a non-Apple brand) and the capacity is only 6200mAh. I was expecting 7000, but it was only $35, so I guess I can't complain too much. My old battery was so swollen it was causing the trackpad to pop out, but I forgot to check coconutbattery's "original design capacity" for that Apple-branded battery anyhow. I'm guessing it was 6500 or 6800? Thanks

    Well, surely someone here has a 2010 MBP they can run any battery program and see the design capacity. I already know I got scammed since I ordered a 7000mAh battery and received a 6200mAh one, but I'm curious what the original Apple battery is.

    V * A = W

    77.5Wh / 10.95V = 7.078Ah or 7078mAh.

    Someone can come and tell me if I'm wrong here, but I don't think the hours part of the measurement affects the numbers at all.

    That is what I thought. But this new battery I got claims 10.95V and 77.5Wh, but coconutbattery is saying the capacity is 6200mAh

    77.5 / 10.95 X 1000 = 7,077

    Thank you. When you open coconutbattery or system profiler does it say 7000mAh design capacity? My battery also says 10.95V and 77.5Wh, but capacity is only 6200

    6900 is the actual design capacity of the standard battery. It'll never be the full 7077

    Ok, so 6200 is indeed a bad battery then. Thank you

    At $35 I'd be more worried about it exploding or catching fire cheap knock off batteries are notoriously rubbish and possibly dangerous.

    If its an original apple battery bought on the cheap it's probably years old.

    I suppose so. It is indeed a cheap knock-off. In a few weeks this is no longer going to be my main computer, though. I was just looking to extend the life a tiny bit. Will be getting a new MBP within the coming years. Building a desktop in the next couple weeks.
