Does a Home Security System Use Batteries?

No matter what type of home security system you have, it will use batteries. For wired security systems, there are typically batteries installed to provide at least a minimum of protection if your electricity goes out. If you have a wireless system, there are rechargeable batteries that you can use.
Typically, these batteries last a long time and warn you well in advance if they are starting to run out.

How Do I Know Where the Batteries Go?

When you need to replace your batteries, your control panel will likely tell you exactly where that battery needs to go. Then, you can either charge the batteries, or install back-ups (which is recommended). Some components of your system may not have batteries, they will simply work until they no longer work and then you need a new piece.

Typically, the following components need batteries to work:

  • Control panel
  • Key fob
  • Keypads
  • Door sensors
  • Window sensors
  • “Smart” sensors and pieces
  • Wireless cameras
  • Glass break detectors
  • Smoke alarms
  • CO2 alarms

You May Need to Alert Monitoring Company

Alarm monitoring companies need to know what you are doing because if they suddenly notice that the signal goes out, they might think that something is wrong. You just need to alert the company that you will be doing it, and nothing will happen.

In fact, they might tell you that it is a good time to do something else to your systems, like reset your keywords or codes, or update your system.

Know What Batteries Your Security System Needs

You should be able to tell what kind of battery your security system needs just by looking at the battery – it will say it. You can also look at your instruction manual where it will tell you. There is no “one size fits all” option for the batteries used in a home security system. Typically, AA batteries, AAA batteries, or rounder, flat watch batteries are used.

However, for many wireless systems, you don’t really need to replace the battery, you just need to charge it. There will likely be a USB port where you can charge the device in just a few hours – like when you are making dinner or are present in the main part of your home.

Restart Your System

Once you have replaced the batteries or you have charged the battery to complete, you may want to restart your device. This can help to keep your system running efficiently so that you can get the most amount of time between charges.
