Thread: AA ---> C or D spacers / case / holder

  1. #1

    Default AA ---> C or D spacers / case / holder

    I looked at all the sub forums and this looked like the best place to put this. If there is a better place to ask then please move it.

    I have seen at some point in the past, I guess you would call a case that is the shape of a C or D cell battery. It opened up and allowed you to put several AA cells inside so that you could use your AA cells in devices requiring C and D cells. I have searched the internet numerous times over the years without any luck finding them.

    Does anyone know where these things can be found? Maybe a better question is if anyone else has ever seen them before? I would love to be able to find some so I don't have to deal with buying C and D cells for the very few things that actually use them anymore. As I buy electronics that require AA and AAA cells, I also buy a couple packages of Eneloop batteries to go with them, so that I now have a large collection of Eneloop batteries and they are basically in any and all electronics in my house that require them. I would much rather use these cells in a special holder to power the few things that require the larger C and D cells.

    If anyone knows where to get them I would love to know. Please PM me or email me if links aren't allowed to be posted.

    Thank you!!!

    I just placed an order for some 2AA to D adaptors off eBay. I plan to try them in my 2D Maglite LED lights with some late generation Eneloops...
    Better to have it and not need it than to need it and not have it.

    If you don't mind DealExtreme (dx.com), they have adapters too

    AAA-AA 4-pk SKU 54457
    AA-C 2-pk SKU 22595
    AA-C 5-pk SKU 13814
    2AA-D 2-pk SKU 7031

    There are two 3AA-D adapters out there. One has the cells in series, the other in parallel. I saw the series one somewhere (battery junction?), but it was pricey. I haven't seen the parallel one.

    Also, be aware that the negative contact may not be large enough for the bottom spring to contact the adapter. I used a piece of folded aluminum foil to allow contact between the last adapter and the spring.
