My ADT system says low battery, how can I change it?

No matter how much you know about your ADT security system, there are always questions that come up from time to time that you will want to learn more about. One of them is how to change the batteries and how to know which type of battery you need.

How Do I Find My Owner’s Manual?

Before you change batteries in your system, you will want to refer to your owner’s manual. Even if you have misplaced your owner’s manual, it is easily accessible. You can review the user manuals we have posted on our website by identifying a photo of your keypad, or log into your account at MyADT.com and then choose the system you have. After you locate your security system, go to the Help Center and click on “find your system manual” where you can download it.

How Do I Replace a Sensor Battery for a Window or Door?

If you get a zone trouble indicator on your alarm keypad or a sensor trouble warning on the ADT Pulse device, the battery in either your window or door needs replacing. This should be done as soon as possible so that your home remains protected. You know that it is a zone battery because it will show a zone number when it says “low battery” instead of just plain “low battery” or “system battery”. 

You can find the batteries you need on our website by going here.  

To prevent the system from having a false alarm, place the system in test mode by logging into the MyADT.com dashboard. Choose the “my alarm” area for the menu that you will need then choose system management.

From there, you are able to put the system into test mode. Or you can contact 800-ADT-ASAP (238-2727) to have it done by ADT via phone.

You will need a flat head screwdriver. Then push in the tab on the end of the contact, which is indicated by an arrow on the contact points in the front area. Place the new battery in correctly, put the front cover back on, and snap it into place to close it. Note that you may have to reset your security system. You can do this easily by entering your code and choosing “off” two times. Then remove the system from test mode.

How Do I Change the Battery in the Alarm System

You’ll need to change battery in the alarm system when it’s low. It will let you know by displaying “lo bat” on the display or send you an alert. (It also could say “low battery” or “system battery”.)

In this case, you will have to order a battery and the alarm panel requires a special Sealed Lead Acid battery. Different panels require different batteries but you can look at the batteries here and let us know if you do not find the one you need. If you need a user manual for your system to find your battery you can look here where we have a list with pictures of most common keypads/panels. If you have a system like the picture above, look here to know which battery to get. 

Once you get your battery, place your system in test mode. The steps are repeated again below

Access your MyADT.com dashboard and select “my alarm.” Once there, choose system management and choose the option, “place system on test.”

Now you will need to open the panel to the system. You may require a key, but you can usually find it at the top left of the panel. Other times you will just need to push down on the tabs on the keypad/panel and you will find a green battery that has a little pin connector.

Now gently tug on the wires to disconnect them.

It is easy to replace that battery. Just connect the black wire to the black tab and the red wire to the red tab. (Or just plug in the new pin connector.) Once you’ve finished, close your panel and remove your alarm system from the test mode.

Keep in mind that you may get a low battery indicator for up to 48 hours. But this is nothing to worry about since it might just need to recharge. 

To learn more useful information about your ADT system or to inquire about having a system installed, simply contact us and we’ll be more than happy to help.

      Yes you can call ADT and have them do it if you would prefer to pay them to do it for you.

    I replaced my battery but screen is still blank. Let it sit for a few days to charge up. I am no longer on the monitoring.

      Please send us a picture of your keypad and we can see if there is anything else we can recommend. Might be a bad keypad or a need for more programming.

    We no longer have ADT service and had to replace the battery pack. This was done a week ago. The caution lights are still on and we are unable to set our alarm as the screen display states we need to secure the system. We do not know what this means. It does not accept our passcode.

      Please contact us and let us know which panel you have. It sounds like you have an open zone or another issue besides the battery that is preventing you from arming the system
