Hard wired smoke detectors need a battery replacement more often than any other batteries. How To Know When To Change Battery In Smoke Detector? Instead, the alarm itself needs a replacement every 10 years. On the other hand, any smoke alarm powered by a 10-year lithium battery doesn’t need a change. While the alarm itself requires to be replaced every 10 years. In case if you have smoke alarms that are powered by a nine-volt battery, then the battery should be replaced every 6 months. How Often To Replace Battery In Hard Wired Smoke Detector? However, if your smoke alarm fails after installing new batteries then your smoke alarm needs a replacement altogether. If the alarm doesn’t go off while being tested check the battery connection or try different batteries that suit the alarm. The alkaline ones would be a bit costly than AA, but they last longer. The AA batteries are most easy to replace but they run out of power very fast. On the other hand, some smoke detectors use AA pencil batteries and others use 9-volt alkaline batteries. Not only smoke but also for detecting carbon monoxide many use 9V lithium batteries that can last up to 10 years.Īlthough 9-volt lithium batteries are the best choice, higher-end models are compatible with lithium power cells. When it comes to choosing batteries for smoke detectors one must look for a highly functional one that is quick to respond in cases of emergencies. What Kind Of Battery For Smoke Detector To Use? The scattered beam of light then gets redirected and meets with a photocell which activates the alarm. Once the smoke reaches and enters the interior chambers the light gets split and causes it to scatter. Photoelectric Smoke Detector: Unlike the ionization process, the photoelectric process uses a steady light beam. Nonetheless, ionization smoke detectors are ideal for home-usage. As the alarms go off, it gives you enough time to move to safety before the air gets filled with toxic substances, lethal enough to cause you death. Whenever the smoke enters the compartments, it happens to create a blockage that interrupts the flow of ions.Īs a result, the whole process reduces the flow of current and triggers the alarm. ![]() This ionizes the air causing the current to flow between the plates. Ionization Smoke Detector: These alarms have a little amount of radioactive material between two electrically charged plates. Let’s take look at the two most popular smoke detector batteries on market. However, it has been observed that the ionization smoke detector is more prone to respond to flaming fires. These two of the most recognized smoke detectors are: To avoid the mismatch and provide options manufacturers have engineered two sorts of smoke detectors. ![]() ![]() Similarly, the one we use in office buildings is not the right match for home. The one we use in home is not adequate for large buildings. The manufacturers have been re-designing and modifying their smoke alarms for better output. 7 Bottom Line Different Types of Smoke Detector
