Some parents report that a standard rechargeable Sonnet 1 battery lasts all school day while using the Roger 21 integrated battery cover receiver and other parents report that it doesn’t last all school day.

You mentioned that your son is around 10 correct?

Changing the Sonnet rechargeable battery is quite simple to do and my kit came with 3 standard rechargeable batteries as well as a small wallet to hold spare batteries.

Some parents choose to use Power One implant disposable batteries.
