Ok, so in terms of convenience and maintenance, the battery-powered smoke detectors can be selected. Its availability and installation process is very simple, and it can be operated by just replacing the batteries. If the user is using disposable batteries, or by charging the batteries if rechargeable batteries are being used.

In this case, hardwired smoke detectors require the attention of the users a lot. The user needs to appoint professionals to install them, as these need to be connected with the main power supply of the house. The main switch needs to be turned off during installation (just saying, anything can happen anytime, I hope you got the point). 

Why do hardwired smoke detectors can not be replaced with battery- powered ones? 

Now to answer the question we are here for, Can You Replace Hardwired Smoke Detector With Battery? Our answer will be NO! Why? We will explain.

As we mentioned earlier, this device can decide the residents’ life and death. So this is something one must not compromise on, both in terms of budget and demand. The extra payment would be worth it, as it would ensure the security of you and your loved ones. 

So, the foremost reason why should one go for the hard-wired smoke detectors is its interconnectivity, which the battery-powered ones don’t provide. What this means is that, since the hard-wired ones are connected to a central power system, they can be connected with each other as well. This would mean that if one of the detectors are triggered, all of the detectors will start the alarms. 

Now, why is this important? It takes seconds for a fire to turn into destruction. Every second is important if something happens. So just think of a scenario: battery-powered detectors installed, and the kitchen is on fire, so the detector only close to the kitchen starts the alarm, and the residents can’t hear it. DONE! A few seconds later, the whole house burnt.

Installing Hard Wired Smoke Detectors does not cost more than your loved ones or your dreams. 

Lastly, one can depend on the hard-wired ones with eyes closed, as long as the main power supply of the house has no problems. However, for the battery-powered ones, you never know when the battery runs out, although it chirps the hell out of the house when the battery power is low. But that still bears a huge risk, as many people have the tendency to ignore such things a lot.


Therefore, we think that Hard Wired Smoke Detectors CANNOT be replaced with Battery Powered Smoke Detectors. Hard Wired Detectors need maintenance and checks regularly, and they need to be replaced after some time, but it’s all worth it considering the degree of its importance.
