Open the control panel. Carefully remove the old batteries and dispose of them according to local regulations. Replace the old batteries with new ones, following any specific instructions or orientations indicated in the manual. Reconnect the power to your alarm system and test it to ensure proper operation.
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.
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.

Some alarm systems operate using a rechargeable battery specifically selected to operate with that device. Something like a 12-volt 4.8 AH rechargeable sealed lead-acid battery runs on a trickle charging system. Trickle charging allows a battery to self-charge at a low rate in order to remain fully charged.
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.
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.
When you order on MyADT, your QSP provides one free system battery per year. Additional system batteries cost $29.99.
Most systems will begin beeping or chirping as a result of a total power outage or failure to recharge the system backup battery. 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.
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.
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.
Make sure to power down the security system before you work to avoid any injury. Disconnect the transformer or flip the circuit breaker switch to ensure power is off while you replace the old battery with a new one.
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.
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.
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.
It sounds like the battery in your main panel needs to be replaced. The battery is located in the main panel box of your system. This box is typically found in a utility room, closet or attic.
If the low battery message does not clear for more than 24 hours after the battery is replaced, then you should delete and re-add the sensor. Although the batteries in your door & window sensors may have a shelf life of up to 10 years, when used in a device, battery life expectancy is up to 2 years.
Requesting a Replacement Battery
If you choose to replace the battery yourself, contact ADT at 1-800-ADT-ASAP to have a replacement battery sent to you or you can purchase one at a local battery supply store.
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.
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.
The normal life of an alarm system battery spans two to five years, and you'll be alerted when it needs replacing. While all systems are different, your alarm system keypad will display a warning message—Low Battery, Trouble, or similar. The keypad may also start to beep at regular intervals.
Low car battery
If your car battery's running low and isn't sending the right amount of voltage to the alarm system, it can set off the alarm. If your car battery is dead the morning after the alarm has been going off during the night, this is a likely culprit.
