I only surmised. They're Bluetooth on a Mac. I get about three or four
months per mouse and keyboard. Both take two AA batteries. So that's
sixteen AA batteries a year at worst. That sounds about right.
There was a time when I thought AAA through D cell batteries would
become obsolete. Boy, was I wrong.
