NiMH batteries?

  1. So I was at Frys today, and I was looking at the NiMH rechargable
    batteries. I invested in a couple sets of NiMH batteries a while ago,
    when I got a digital camera. I have a couple sets of the 2300 mAh AA
    batteries. I noticed that they have 2500 mAh AA batteries now. But
    then I noticed that they had some 2500 mAh D batteries as well. Now it
    occured to me that since they are both the same voltage, 1.2v, but the D
    size are obviously bigger, shouldn't the NiMH D batteries have been more
    than 2500 mAh, which is what the AA ones were?
  2. Even in the NiCd battery days, D cells often had the same "innards" as a
    C cell but with a "sleeve" to make them D-size (although I did once have
    some 4000mAH NiCd D cells). Now it seems that the NiMH D cells often
    have the same "innards" as an AA cell.

    Perhaps higher-capacity NiMH D cells do exist, but Fry's doesn't carry them.

    looking into a list from a shop, I find D cells with 3000, 5000 mAh or
    8000 and even 9000 mAh.
