Eneloop Panasonic BQ-BS2E4SA C Size Battery Adapters for Use with Ni-MH Rechargeable AA Battery Cells, 4 Pack

Works perfect for UNO Flip Attack Card Game with Launcher Unit which was needing D cells!

Fantastic product, very easy to use. Great value!

Any dollar item adapter will do just as well as this product, imo - however, I feel, if I had to blow money on Eneloop batteries then I would like to show them off, no matter what size battery is needed..

I bought them in May of 2018 and 7 years later as of June 2025 I am still able to use them. Quality product.

Doesn't last as long as actual C batteries - but who the heck has C batteries laying around? It's a good substitute for my casette recoorder that needs 4 C batteries - and Enloop's are the best rechargeable batteries.

Why did you pick this product vs others?: Great product works as stated. Worth the money and eneloop batteries work really well and as stated, maintains power even several months in storage of at least 70%. I've tested this several times already and it does in fact do that. Best, brand of batteries rechargeable wise you can buy

I have a garbage can in the kitchen with a motion sensor opening top, so it gets used a lot. I have an extra set of AA Eneloop rechargeable batteries, so now I can use those, without the expense of purchasing (rechargeable or not) C batteries. It works great, they just snap right into the sleeve, and they fit just right into the C battery slots.

I have lots of AA batteries, but a few odd items require C batteries. This adapter solves the problem perfectly. No need to buy throw-away C cells, just adapt your rechargeable AA batteries. Would buy again, would recommend to a friend!

This worked like a charm! Much easier to use common batteries AA than C for just the odd cat toy! Quality is good fit in good worked great. Happy with this product.

a bit exspensive for what they are just a plastic cover for aa battery to turn it into a c type battery but do the job work fine no problem and do the job

Excelente producto!! La mejor opción ya que no existen pilas recargables en el mercado tamaño C (al menos en Mexico) cumplen perfectamente bien su función, las recomiendo ampliamente!

not practical, difficult to fit

I hate C batteries with a passion normally reserved for animal abusers and blizzards, but we needed a few for our new Surefeed Microchip Pet Feeder. Rather than buy a bunch of disposable C's, I decided to buy these adapters so I could use my existing Eneloop batteries. Simply slide them into the C adapter and you're ready to go.
