2-pc. 9V Super Heavy Duty Batteries

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. These 9V batteries are obviously great for many of the devices you use on a daily basis. Batteries are also great for storm seasons or medical needs, to the holidays. Panasonic is a leading battery brand so you know it's a battery you can trust!
