A low battery warning is most often displayed as BAT, LOW BATT or SYSTEM LO BAT on the touchpad. This warning signals that your battery is low and must be either recharged or replaced.
To inform you of a low battery so in case of a power failure (or just battery powered detectors) that the back up is about to die and that unit will stop functioning (it's the law too that manufactures do that).
If there's a low battery warning, you might need to replace the alarm system's battery. If the alarm persists after replacing the battery, consider power cycling the entire alarm system. Turn off the main power supply to the alarm, wait a few minutes, and then turn it back on.

An ADT Alarm System's low battery beeping can be silenced by pressing the ``OFF'' button or ``#'' button on your keypad.
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.

In most cases the alarm system will activate or at least beep if there is a low battery or if the alarm system battery dies.
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.
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.
You will see low batteries as a trouble condition on your home screen in the Control app. Tap the trouble icon to see a list of devices with a low-battery condition.
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.
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.
Go to your main control box and disconnect the battery supply, which will stop all beeping and shut your alarm system down. Once power is restored, you can reconnect your battery and your alarm system should work as before.
Yes, house alarm systems work when there is no electricity as long as there is a backup power source. But you should keep in mind that even with a backup, there is still the potential for the power source to go out, and the house alarm will go off if the battery dies.
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.
The most common meaning of a low battery warning is just that – your security system has been running on battery power for an extended period of time, and the battery is low. Because of this common cause of the warning, it's often recommended to wait up to 24 hours to see if this warning goes away on its own.
False alarms are a nuisance for everyone around you, including the police and your neighbours – they can even make some people hesitant to use their home alarm system. The most common causes of false alarms are operator error, improper installation, including poorly positioned motion sensors, and a lack of maintenance.
Disconnect and Reconnect the Battery:
Reconnect them in reverse order. This action can reset the vehicle's systems, including the anti-theft system.
The source of a low battery signal may be either the system backup battery, or it could be from a sensor, like a door sensor, smoke detector, or glass break sensor.
