I would avoid attaching potential future prices to these products. It will end up being a distraction in the long run. Money is not a constant. I could elaborate but then...you know...

Edit: Didn't read whole thread, found my answer.
Thanks for the links Bones.
$15.47. No thanks! I'll pass.
Nice work Bones, thanks
metlarules, before you jump to conclusions ....
Prices in US are often lower. For instance, he lists 4 AAs @ $13.62
while I bought them from TD on sale for $9.97, or 27% discount
So D eneloop @ $15.47 discounted to US level would be $11.30 for 5.7Ah
So I can get 8Ah from 4AA package for a buck less. sigh
It is just so hard to justify D format cells with so much better pricing for AAs.
Even at $10 a cell it's expensive for 5.7mah. Don't get me wrong I'm sure Sanyo will put out a quality product.It's just that I will save my money until they increase the capacity to at least 10 mah.
I've just noticed what may actually be some good news about the capacity of the Eneloop C & D cells.
The e-life-sanyo.com site lists all the Eneloop cell capacities at their minimum instead of typical capacity, ie: 750mAh instead of 800mAh for the AAA cell:
If this analogy holds, then the typical capacity of the D cell would probably exceed 6000mAh and, more importantly, should never fall below 5700mAh:
PS: Also just in, Eneloop C & D cell and Universal Charger pricing report in post 64.
Why should they develope a new production process if they can just reuse their current parts for _exactly_ the same device properties?
It's too suspicious, isn't it?
Min capacity for AA = 1900 mAh.
Min capacity for D = 5700 mAh.
3 x 1900 mAh = 5700 mAh.
Looks like someone will need to 'Operate' once these become available.
Well someone's going to do it. And it really does look like we can guess what will be inside.
So, does anybody currently make a 3AA-to-D adapter shell that configures the cells in parallel instead of series? If not, why not? If so, it must be hella cheaper than one of these "new" Eneloop D cells. Wouldn't mind having a few adapters like this to use with my AA's as backup to my PowerEx D cells.
This is starting to smell like the Energizer nimh d cell with 2500mahonly with 3 aa cells.
Well this settles it, then... I'm sticking with NiCads or some other LSD NiMH brand...

This Eneloop C and D cell adapter theory is getting interesting, but I remain very skeptical.
According to the Eneloop specifications, an AAA cell weighs 13 grams and a C cell weighs 60 grams:
In order to abide by the 4 AAA cells into 1 C cell theory (4 x 750mAh AAA cells = 1 x 3000mAh C cell), the cells themselves would account for 52 grams, leaving just 8 grams to account for the top and bottom metal contacts, the adapter body and the ptc.
It this enough?
The weight issue doesn't appear to be as critical with the 3 AAA cells into 1 D cell theory (3 x 1900mAh AA cells = 1 x 5700mAh D cell).
According to the Eneloop specifications an AA cell weighs 27 grams and a D cell weighs 100 grams:
In this case, the 3 AA cells would account 81 grams, leaving 19 grams for the remainder of the D cell.
These 'exploded' views of the Energizer D cell may provide some clues as to what's involved with the type of implementation being theorized for the Eneloop C and D cells:
The next question I have is who is going to be the guinea pig?
There's no need to take one apart. It just needs an X-ray machine. Take some through an airport and look at the screen as they get scanned...
Good point. Also,if we have any xray techs out there they could take one to the hospital for us.
It'd still be cheaper and easier to just take one apart.
I don't get that.
Cost of X-ray: $0
Cost of taking one apart: $12+
Now that you have a big casing, you can leave out parts of the individual casings, which shaves of a gram or two per cell.
I also dont quite understand why you think that 19g for "the rest of the parts" would be little for a D-cell.
Thats quite an amount of heft, and a strong steel-can as big as a d-cell wont be as heavy.
Also, in the pictures you showed, i do not think those plastic parts weight more then 4 or 5 grams. A cm^3 is good for a lood of thin stiffening parts....
