Smoke detector with replaceable battery
From Encyclopedia Dramatica
A smoke detector with replaceable battery is a smoke detector that features a replaceable battery. Smoke detectors with replaceable batteries are currently illegal in the state of Illinois following a string of super-intelligent African Americans being burned to death because they were too fucking stupid and lazy to replace the batteries in their smoke detectors with replaceable batteries after they started chirping.
Smoke detectors with replaceable batteries are notable for being literally the only electronic device in existence that requires a 9-volt battery.
