EBL C Size Battery Adapters, AA to C Size Battery Spacer Converter Case Use with Rechargeable AA Cells - 4 Pack

Worked great in my automatic open trash can I bought. No need to order more sizes of batteries I do not need.

These sleeves do what they are supposed to do which is to allow a AA battery to fit into a C battery slot. The AA battery doesn’t lock click into the sleeve but simply slides into a sleeve . Just a personal preference that a click lock would be better but it worked good in the application I needed them for. I’m sure I will have to replace the batteries more often due to lower amp hours but you can use rechargeable AA batteries to mitigate cost in the long run.

I have these in the D size, the sea size just didn't seem to work in the product I have, the batteries kept popping out of the holders so I couldn't use it. Had no problems with returns, I would have kept if it would have been in a different product Maybe. Can't really complain, as I said I have some in a different size but I just couldn't use these particular ones.

Just need an option to use chargeable double a batteries instead of buying batteries I don’t have charger batteries, but this worked out better

Great idea snd works!
