To disconnect an ADT backup battery, first place your system in Test Mode, then unplug the system's power transformer from the wall. Next, open the main metal control panel box with a key or screwdriver, disconnect the black negative wire, followed by the red positive wire from the battery terminals.
For many of our most popular systems, beeping alarms and low battery trouble beeps can be silenced by pressing the [OFF] or [#] buttons from the keypad.
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.
Whether your house alarm will work without a battery depends on the type of alarm and the power situation:
Open the front of the alarm panel, it may be held in place by a couple of screws. Once inside locate the battery, the battery will have two connections, a red and a black, remove both of these connections.
Yes. Low voltage or a disconnected battery can reset or confuse your vehicle's security system, causing it to block ignition. After replacing or jump-starting a battery, the system may need to be reinitialized properly.
The lifespan of an ADT backup battery depends on the context of your question.
To immediately silence the beeping, enter your system's disarm code, press the # key, or press * then 2 to acknowledge the trouble alert. To stop it permanently, you must either replace the backup battery or disconnect the system from both AC power and the battery.
Order Summary
When you order on MyADT, your QSP provides one free system battery per year. Additional system batteries cost $29.99.
A battery backup (or UPS) beeps to alert you to an issue. The beeping pattern and its meaning can vary, but here are the most common causes:
Entry delay is the time between when a sensor is tripped and when the burglary alarm sounds, providing time for you to input the passcode to turn off the alarm. This can be set differently for each individual sensor and defaults to 30 seconds.
Even after the battery has been removed, the detector maintains a residual charge that will keep the chirp going for some time. To get the device to stop chirping once the battery has been removed, you must drain this residual charge by holding the test button for 15 seconds.
You should leave the battery disconnected for at least 15 to 30 minutes. This gives the vehicle's electrical system and computer capacitors enough time to fully drain, forcing the Engine Control Unit (ECU) to reset.
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. You can learn how to silence your specific panel by visiting our Silence Low Battery Beeping page.
ADT does not offer a standalone "senior discount," but seniors aged 50+ who are AARP members receive 5% off monthly professional monitoring services. To redeem this, you must call ADT directly (e.g., at 1-800-973-0958) and provide your AARP membership number.
Battery replacement is not covered under any warranty. If you require services excluded from coverage, then ADT will provide the services at its current labor rate for each service call.
To temporarily silence your ADT low battery alarm, enter your [security code] + [OFF] or just press [#] on your keypad. For touchscreen panels (like ADT Command), tap [Disarm] and enter your security code.
Yes, a bad or low battery can cause both car alarms and home security alarms to go off. It is one of the most common causes of random, unexplained alarms.
To silence an alarm beeping due to a low battery, you must either acknowledge the trouble alert on your system, remove the depleted battery, or replace it entirely.
Whether your house alarm will work without a battery depends on the type of alarm and the power situation:
A UPS (Uninterruptible Power Supply) battery typically needs replacing every 333 to 555 years. You should replace it immediately if the unit beeps constantly, fails to hold a charge during a power outage, or if you notice visible physical damage like swelling or leakage.
