How to Change the Battery in ADT Motion Sensor? Easy Steps!

Motion sensors are used to detect motion. An ADT motion sensor is also a protection and security device designed to detect motion in a specific perimeter and alert the users of any suspecting movement. ADT, as a security company, provides a wider range of security solutions. These motion sensors use PIR technology which is passive infrared technology. This technology is used to detect movement. It sends signals to the control panel or monitoring center. This uses an alarm system that alerts the owner of any potential threat. Let’s is how to change the battery in ADT motion sensor.

Do ADT Sensors have Batteries?

The ADT sensors are used with other security devices, such as doors and window sensors, alarms, and cameras. This provides a comprehensive home security system. This motion sensor can help prevent burglars, intrusions, and security and protection threats.

The ADT sensors do function on batteries. ADT motion sensors like window and door sensors and smoke detectors use battery power. This makes it easier to install without any wiring or electrical outlets. The battery used in these sensors depends on a specific type of sensor. Some use standard alkaline batteries, such as AA or AAA, while others use lithium batteries.

Certain factors like environmental conditions, sensor usage, and battery type affect the life span of ADT sensors. Make sure to check and replace the battery regularly. These sensors have indicators that will alert the user when the battery is running low. 

Can you Change the Battery of the ADT Motion Sensor?

Yes, the ADT motion sensor battery can be changed. Many ADT motion sensors are easy to install and maintain. If you want to change the battery in your ADT motion sensor, follow these steps:

  1. There is a battery compartment designed at the back of the motion sensor. This compartment is either secured with a sliding latch or with screws. 
  2. Next, remove the old battery. The battery replacement depends on the nature of the sensor. A screwdriver or any other tool can open the battery compartment.
  3. After removing the old battery, replace it with the new one in the compartment based on the instructions provided.

How Do I Know If My ADT Battery is Low?

Based on the type of ADT motion sensor you use, the battery types and how it is detected when the battery is low differ accordingly. Many of the ADT sensors have an indicator to indicate when the battery is low. This indicator will alert the owner when the battery is to be replaced. There are a few ways to identify whether the ADT sensor battery is low.

  1. Check the motion sensor battery power using the control panel- one can check the battery power status with the message displayed or the icon indicating the battery is low.
  2. Another way to find out is by checking the sensor device- some devices have a built-in indicator, which is a light that blinks or changes color as the battery is low. one can check the sensor manually to look for details indicating an inferior status on the battery.
  3. Some motion sensors have a monitoring center that sends an alert notification that the sensor battery is low. This may be through email, text, or phone.

Replace the battery as soon as you can if you notice that the battery is low. 

Can I Recharge My ADT Battery?

Not all ADT motion sensors have a rechargeable battery. Whether it can be charged or not depends on the type of battery used. Some ADT motion sensors use AA or AAA alkaline batteries. These are not rechargeable. So, such batteries run low, and they need to be replaced. Some ADT motion sensors use lithium-ion batteries, which can be recharged using a charger or plugging the sensor into a power code.

Instructions are provided in the user manual to charge the battery. Each manufacturer has their own set of instructions provided, so apply accordingly. Do not ever try to recharge a non-rechargeable battery. It can be dangerous to charge; it can damage or explode the sensor or the battery. 

How Do you Remove an ADT Sensor Cover?

The methods used to remove the ADT sensor cover depend on the type and nature of the sensor used. Here are a few steps used to help.

  1. First, locate the sensor cover; this cover is located at the back of the sensor. It is placed with clips, screws, or a sliding latch. Use the right tool that fits the cover removal. The tools used commonly are pliers, screwdrivers, etc.
  2. If the ADT cover is latched with screws or clips, use a screwdriver or any other suitable tool, remove the nails, and place them aside safely.
  3. Now, slide the cover off using your fingers and remove the cover. Now, remove the battery from the cover and do the needful. For example, clean and maintain the battery compartment or remove and replace the battery with a new one.
  4. Once done, reattach the battery compartment cover by reversing the method of removing the cover.

Some sensors may be designed differently. Use the user manual and read the instructions carefully to prevent any severe damages that may occur.

How to Change the Battery in ADT Motion Sensor?

One can follow a few steps to change the battery in the ADT motion sensor.

  1. The first step is to locate the battery compartment at the bottom of the back of the motion sensor.
  2. Get a screwdriver or any other tool to remove the battery compartment cover based on the type of sensor you use. Once the cover is removed, remove the old battery from the compartment and place the new one inside. 
  3. Now, place back the battery compartment cover and screw back the nails or the clip onto the compartment. 
  4. Next, test the sensor to make sure that it works properly. To check whether the sensor is working, move or walk across to check the sensor.

It is important to use the right type of battery that helps it work. Follow the producer’s instructions and change the ADT motion sensor. 

How Long Do ADT Sensor Batteries Last?

The duration of the battery sensor depends on the type of battery and sensor model, and usage pattern. Usually, ADT sensors use alkaline batteries. These batteries last nearly two years or even more with standard usage. If there is frequent movement or activity in the monitored perimeter, the battery life will be short.

There are lithium batteries used; such batteries are rechargeable. Such battery life lasts up to many months and even years before it needs another charge. This entirely depends on the usage and type of sensor.
