    Can anyone tell me the difference between a BP-511 and a BP--511A battery?
    I have a BP-511 battery that came with my Canon EOS 5D and a BP-511A that came with my Canon powershot G5 and the G6.
    Both of these batteries are the same size and have the same contacts and the same voltage. They even both use the same charger. But there must be a reason for the 'A' designation on one of the batteries.
    Can anyone help? Are there any potential problems swapping them between the 5D and the G5/G6?
    Thank you

    Does either camera have 'Intelligent' battery level monitoring?

    I'm not sure but I think you might find that the mAh rating is higher on the BP-511A.

    What is "'Intelligent' battery level monitoring" and how would I know if my cameras have it?

    The BP511A is an uprated BP511, just, as Terry said, a higher rating for longer life. No problems with swapping between the 5D and the G5/6.

    Intelligent Battery Monitoring is something that came in with the 5D MkII - as I understand it the battery has some form of chip in it which the camera can use to identify it and record the use and charge levels. The camera can remember and identify several batteries this way.
    Not sure what real-world advantage it has, other than bumping the price up and stopping people using the el cheapo (yet very good) 7dayshop BP511 alternatives Wink

    For my 20D I had one genuine Canon battery and a respectable third party equivalent. The third party battery works fine but has only ever held half the charge of the Canon battery. For my more recent 5D MkII, it did not seem sensible to cut corners with a spare battery (apart from the intelligent monitoring) the increased capacity is well worth having. Of course I would have liked to pay less than 60 but having spent nearly 2,000 on the camera, it did not seem sensible to choose an inferior vital component.

    That is because it is a cheap Chinese copy filled with very poor quality low output ni cad cells and not NIMH cells, despite what the fake makers claim, uniross and Hanel do make a NIMH loaded equivalent that works but it cost around 18- 25 .
    What should be noted is that the fake e.bay batteries are not designed to be charged at the high currents put out by the canon charger and usually fry and fail quite quickly...

    Well, if that's true I wouldn't touch a Uniross nor Hahnel with a bargepole either - they are supposed to be Lithium Ion Wink

    I've never had any trouble with 7dayshop BP511 equivalents, they have all lasted as well as (or better than) the Canon ones, both on charge life and overall life.

    The BP511a is a higher capacity and I believe it can also be used in certain Canon camcorders. Smile

    I have a question: will they third party camera battery bp 511 also has Intelligent Battery Monitoring? like this one: http://www.digital-camera-batteries.net/canon/bp-511.htm .

    No - the BP511 does not have it so the third-party ones won't.
    The one that does (for the 5D MkII and, undoubtedly, future cameras) is the LP-E6
