Your cart is empty.Panasonic Eneloop c-size and d-size battery adapters. Even though 85% of all disposable batteries sold are either AA or AAA size, there are still some applications, which require other battery sizes. The two next common sizes are C and D. Typical examples, where these sizes are required are big flashlights or portable radios. For these cases Panasonic offers simple but smart plastic adaptors, which transform a aa-size Eneloop into either a C- or d-size battery. Just plug the Eneloop into the Adaptor and you can use it in your equipment. Of course the adaptors only adapt the mechanical dimensions of the Eneloop (length and diameter) and obviously not its electrical characteristics. The voltage and the capacity remains unchanged to the Eneloop AA specification. This product is manufactured in Japan.

I like the recharging capabilities for these. These seem to fit just like the regular size batteries. Great sub for the actual batteries. Highly recommend.

This is such a smart little invention and a must-have for those who've bought into Eneloop (or other brand) rechargeable batteries. I have countless Eneloop AA's and AAA's but invariable encounter kids toys and other devices that require C or D batteries. These spacers are so simple - open the spacer cap, insert a AA battery into the spacer, screw the cap closed, and voila - your AA has turned into a C or a D battery. It's a really inventive solution to a common problem.

Excited to purchase this. I don’t need to worry about buying different sizes of batteries. This will help create less waste and is easy to put in the AA batteries and take them out. Fast shipping.

This is a great group of C and D battery spacers plus a storage container for four AA batteries. These are genuine Eneloop spacers and they hold AA batteries securely. I have several lanterns and flashlights that require C or D batteries but hate having to store those types. I'll be using these for camping as well as my zombie apocalypse bag.

Purchased for use in a Hot Wheels car launcher. I do not have C or D rechargeable batteries, nor do I have a charger capable of holding those sizes. Adapters work just fine - have only tested the D size so far. Set includes 4 each of C and D.For the Ds, you unscrew the bottom and place a single AA inside. You definitely need to use higher-quality AAs to get these to max output, as I tried lower mAh AAs and the output in the toy was quite poor. But switching to black eneloops, the output was good.Yet to test how long AAs last in a D capacity, as I have no point of comparison against rechargeable Ds.

These work well and are easy to use. Not sure some of the less expensive alternatives wouldn't work as well. I

These AA converters are great but do NOT expect the same power as a normal C or D cell or you will be disappointed. They work best in lower drain devices. Kids toys work great usually since kids burn through batteries and AA are much cheaper in bulk. I know some will say "just get rechargeable lithium" but if you do the math and figure in charging, storing and MUCH higher cost you will find these to be a more economical choice than buying any kind of C or D cell batteries especially lithium.

Wasn't sure about the viability of these, but I bought them to use with my panasonic rechargeable batteries. When I got the spacers I tried them and was pleased that they worked as advertised. I primarily use the AA in the C spacer. Only small nit to pick is that they don't have screw on end like the D so one has to be careful when inserting the unit with batteries. But I really like the idea of using the eneloop batteries. I may have to recharge frequently for some applications when using with the C and D spacers but sure beats spending money on throw away batteries. Good purchase.

Tried them out. I think I will get lots of use out of these holders. At the moment seem well worth the purchase.

Este set de convertidores de pilas de AA y AAA a C y D es una verdadera maravilla. De inicio me quita el problema de comprar baterías C y D (de las que no he encontrado recargables) y también me quita un dolor de cabeza con el precio. Ya las he usado en un par de productos y funcionan bien, y aunque me el rendimiento de la batería es menor (al ser AA no dura lo mismo que una batería D), eso lo soluciono con un set adicional y listo. Soy papá y algunos de los juguetes de mi hija tienen requierimientos altos de baterías y estos espaciadores o convertidores han quitado el problema de raíz.OJO: Te recomiendo que utilices baterías recargables de alta capacidad para que el rendimiento no te decepcione.

I bought this set & a supplemental set & I am really pleased with this purchase. I use these all the time. There are some items in my home that get used often enough to make the re-usable /rechargeable batteries so worth it. What I really like is the C & D sizes. Those get so pricey & for larger items like lanterns & window candelabra's , that use a lot of Size D's at once, this has really paid off. I hated going through 4-8 D batteries all at once every couple of months on each item. I find they hold their charge well so far. I have recharged the same AA's at least 5 times now & haven't found them to lose their quality or integrity yet. I would definitely recommend & buy again.
