No, Sonic is designed to work with lithium-ion batteries (4xAA's).

But, I have been using rechargeable batteries and they worked just fine?

Sonic is not supposed to work with any other batteries aside from lithium-ion ones, so even if it does work for a week or so, we cannot guarantee that it will stay functional. Therefore, we recommend that you always use the lithium-ion batteries.

If you would like to speak to us in regards to this, please feel free to drop us a line.
