If that battery is dead when the mains power is cut, the control panel battery is unable to keep the system running. So the alarm isn't informing you there's an intruder, it's informing you there's a problem with the alarm.
Wired Systems: Most wired security systems are connected to the main power supply and will continue to function even if the backup battery dies. However, if the system has a low battery alert feature, it might trigger an alarm or send a notification.
System Operation: The alarm system will typically continue to operate as long as it remains connected to the power supply. Removing the batteries usually does not affect the primary functionality.
Comments Section Yes, you can and should change it yourself. The battery isn't in the keypad, it's in the alarm control box. This box is usually in the basement or utility closet, and will look something like this. After you find the box, open it up.
If so, the device will run on its backup battery for up to 24 hours, and you will get a low battery alert as it is depleted. If AC power is not restored before the battery dies, the device will power down. Once the power comes back on, the device will turn on, and the backup battery will begin to charge.
When you order on MyADT, your QSP provides one free system battery per year. Additional system batteries cost $29.99.

Home alarm system battery replacement cost
The typical cost of a replacement burglar alarm battery is between £12 and £30 depending on the type and make of battery.
Most manufacturers recommend changing your system's battery every 3–5 years. Newer devices may last up to 7 years. If you don't know when your system was last serviced, start looking for a replacement battery now.
The beeping sound the low battery alarm makes can become very annoying but can be disconnected by removing the drained battery from your home alarm system panel. Make sure to replace the drained battery with a new one to keep your home alarm system functioning properly.
If the keypad for your home alarm system starts beeping, it's a sign that the power supply is low and the battery might need to be replaced. The keypad may beep infrequently at first, but it will beep more consistently as the power supply drains.
We recommend changing all your wireless sensor batteries on an annual basis or as directed by your ADT system.
Many alarm systems will beep when the battery power is low. You may hear a beep every few hours or once a day when the system runs its automatic battery test.
Turning off a security system alarm during a power outage may seem impossible, but there are ways to accomplish this on your own. The steps to powering down an alarm without a keypad available include locating the main source of power and removing and the backup battery.
Yes. In case of a power loss, the back-up battery will activate and will operate your alarm system for several hours. In the event your system battery is or becomes low, a low-battery signal will be sent to ADT's Customer Monitoring Center.
All good alarm systems have back-up battery power. It ensures they remain for at least 12 hours in the event of a power outage (power cut). When power is restored following an outage, the system is designed to start working normally and also recharge the battery. All batteries have limited life.
98% of the time an alarm rings during a power cut is because this battery is dead! Therefore when the mains is removed, the main control panel battery can't keep the system running so the external sounder starts ringing to inform you there's a problem.
The system battery is a backup power supply. If you have experienced a recent power outage or if your system has been running on battery power rather than AC power for any other reason, it may just need to be recharged. Allow your system 48 hours to recharge the system battery.
Most systems continuously beep to alert you that batteries need to be changed. This is true for both security panels and detectors. Go through your home, and test all batteries associated with your security system using a battery tester.
You typically will not need to do anything to reset your car alarm after a battery change, but it should automatically reset for you. Some vehicles or alarm systems may require you to push a reset button on the alarm box that may be located near the steering wheel.
How often should I get my burglar alarm serviced? A good rule of thumb is to test your systems every six months. At a minimum, get a professional to service your set up annually. If your burglar alarm system is playing up, it's worth getting it serviced right away.
You can either have a wireless sensor that is powered by batteries inside the individual units. Or, you could have ones that are hardwired. These hardwired sensors would run directly from the back up battery and the power transformer with no batteries necessary.
The alarm in your home security system is designed to be a deterrent to intruders, as well as alert occupants and draw attention to your home, whether that be from neighbours, passers-by or authorities. Systems will sound for about 5 to 10 minutes, depending on the system, before stopping and automatically re-arming.
Environmental Factors – Open windows can let in wind which can cause objects to move and trigger sensors. Obstructions To Sensors – Dust, cobwebs, or even larger spiders near the sensors can set it off. Electrical or Battery Problems – A low battery or power fluctuations can lead to alarm malfunctions.
