I've just come across these and I have to say, they sound tempting. I've been swearing by Recyko batteries ever since I got them, but lamented the lack of C and D cells. Now I found (?) a solution. I have two major concerns, though:

1. Do these work with other brands of batteries?

2. Do these work at all?

P.S. And what about these?

I don't have any direct experience with the Eneloop adapters, but Sanyo is rolling out true C and D sized Eneloops starting in Japan next month. You can read about it here . No idea when they will be selling them in the US. Oh, and a new charger that will accomodate all Eneloop sizes.

I have used adapters in the past and they do work but you--obviously--have much shorter runtime that you would with a true C or D-sized battery. The fit can be problematic depending on the capacity of the cells. Unlike alkaline AA's, which seem to all be pretty much the same size, higher capacity NiMH cells tend to be a bit fatter and may not work in adapters designed for a lower capacity cell so they may or may not work with your cells.

Edit: Wait, not sure why I'm fixated on Eneloops. Low self-discharge C and D cells are already available from Accupower, too.

Mmmm.... shouldn't it be possible to just file off the sides a little so the batteries fit?

If your Reckyo's are too big and if you can file the adapter to fit them, they will work in any adapter like these. Same thing for the parallel adapter in the second photo.

I just got these recently to help me stanardize my batteries. Haven't had eneloop batteries in them but the lithium ones pictured work just fine.

Where are you guys getting the double capacity ones from? I'm only finding the adapters that take single batteries...

And more importantly, who wants to send me some?

Group buy, group buy, group buy!

I'd like to know where to get the 2xAA to D adapters as well. I really want to replace the ones that came with my eneloop charging package.

Thanks for any info!

Here are the ones I intend to get unless somebody stops me.

Then I'll get some of them, too.
Thx

Wait, his shipping is per item. He wants to charge me $24 shipping for 12 of them.
No thanks.

Meh, eBay shipping is usually a large part of the price. There's a reason individual item cost is so low.

Works out at $20.64 for 12 at rather than $38.28

Oooooh, that is a good deal. I can treat myself to another pack of Recykos, too. Do these offers expire?

I don't think so. Although it appears if they have trouble with US customs the product line may become unavialable.

Well, as long as they have no issue with Israel...

2-packs are even cheaper
16.08 for 12. THAT's a good deal

Took the plunge. Now I just have to wait a few weeks for it to get here...

But these aren't the same converters, are they?

The description is SoShine 2xAA to D-Size, so they should be the same. I'll let you know for sure in a few weeks :p

Sweeeeet!

Thanks for finding these!

Oh woe is me!

Check out the extra reviews: they say the contact area is too small for the Maglite spring.

Any idea how to fix this?

I bought some Enelopps but like the last guy said they don't work in Maglights. The bottom spring is too large. When are they going to sell the new C and D sizes here in the states?

Lol, that's exactly why I got these converters - D cell maglites.
I suppose some conductive foil on the bottom of the convertor would increase the contact area as long as you were careful not to short on the sides of the tubes.

Gotcha. First one with a working Maglite posts pictures! >:)

That's what I was thinking of purchasing the converters for, myself.

One of the posts mentions that using a pair of pliers to bend the MagLite spring into a tighter circle worked.
