USI 10 Year Sealed Battery Smoke Detector

Sealed batteries are a type of lithium or alkaline battery made for smoke detectors, with a lifespan of 10 years. They were designed to prevent issues associated with faulty replaceable batteries, such as malfunctions or delays in smoke detection. Sealed batteries are nonreplaceable, meaning that when the 10-year lifespan is up, you replace the entire smoke detection unit rather than just the battery.

A large benefit of sealed batteries in smoke alarms is the elimination of low battery chirps, which are a common nuisance in homes. Instead, sealed battery smoke alarms give an end-of-life warning, so you know when it is time to replace your device.

USI Electric’s sealed battery smoke detectors come with a 10-year Permanent Power battery that does not require replacement. Some of their devices also have hardwiring options for extra power source reliability.

A smoke detector beeping could indicate a few different things. Sometimes it is clogged with dust or has faulty wiring, but most often your smoke detector beeps because the battery needs to be replaced.

Even if your smoke alarm is hardwired, most devices still have a backup battery in the event of a power surge or power outage. Making sure your smoke detector has a working battery is important for fire safety, so if your alarm is beeping, replace the battery as soon as possible.

Common batteries that smoke detectors use are 9V and AA. Most smoke detectors have instructions on the device itself that indicate what battery it uses. In any case, you can always consult the owner’s manual from your device’s manufacturer to find the battery type.

Sealed battery smoke detectors, on the other hand, use nonreplaceable lithium batteries that last up to 10 years. If your sealed battery smoke alarm is beeping, it is likely time to replace the entire unit.

USI’s sealed battery smoke detectors do not make noise outside of their alarms, other than an end-of-life alert when the 10-year lifespan is up. If you want to prevent frequent noise disturbances from your smoke detector, then invest in one with a sealed battery.
