The most well-known use of the 9-volt battery is in smoke alarms or carbon monoxide detectors. Smoke alarms or, in some cases, heat-sensitive fire alarms use 9-volt batteries as the power source. It is generally recommended that the batteries in a smoke alarms and carbon monoxide detectors be changed about every six months to keep the batteries fresh, as the charge can dissipate over time. Other common uses for 9-volt batteries include radio controllers, clocks and walkie-talkies.
