>OPEN DRILL
Opening the portable drill reveals a C battery.
>EXAMINE DRILL
This waterproof wonder features a permanent bit, a panel which is open,
revealing space for a C battery, and a switch which is in the "off" position.
This is because DRILL-F only checks if there's a working battery inside. If the battery has been drained or damaged, it doesn't show:

For reference, the metal detector does it differently even though that too only can contain the appropriate battery as far as I can tell.
