Although there is some variation in battery longevity, most batteries in alarm systems today will last somewhere between three and five years. Battery lifespan is affected by the kind of batteries that you use and how often you use the system.
The most obvious indicator that its time to replace your alarm battery is when the low battery alert for your alarm system flashes on for no apparent reason. Make sure that the replacement batteries you use are the same type and capacity as the ones you're changing out.
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.
Alarm panel batteries should be replaced about every five years. However, this amount of time can vary between different types of batteries and how often the panel switches over to its backup battery power. The system should display a warning message when the backup battery is low.
HIt depends on the type of battery and the clock's power consumption. On average, alkaline batteries need replacement every 6–12 months, while lithium batteries can last 2–3 years.
Batteries should be changed in your clock at least once per year. We recommend changing batteries at Daylight Savings Time, or annually when you change the battery in your smoke detector. When batteries are left in a device for a long period of time (over 1 year) they have a much higher chance of leaking.
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.
DIY Battery Replacement
Use your access code to disarm and disconnect your security system from power. Open the control panel. Carefully remove the old batteries and dispose of them according to local regulations.
We recommend changing all your wireless sensor batteries on an annual basis or as directed by your ADT system.
Disconnect and Reconnect the Battery:
Reconnect them in reverse order. This action can reset the vehicle's systems, including the anti-theft system.
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.
Although there is some variation in battery longevity, most batteries in alarm systems today will last somewhere between three and five years. Battery lifespan is affected by the kind of batteries that you use and how often you use the system.
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.
System Issues – Possible wear and tear, outdated components, or the need for servicing may cause false alarms. 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.
Change the batteries
There is always a chance that it's a weak or low battery. In today's connected smart homes, sensors, detectors, and the panel itself, all function on batteries. Alarm beeping is a built-in warning that signals the power is fading, and that a new battery will be required soon.
When you order on MyADT, your QSP provides one free system battery per year. Additional system batteries cost $29.99.
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.
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.
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.
Although the main source of power has been disconnected from the home security system, the backup battery is still providing power to the alarm. A screwdriver may be required to access the battery box and you will need pliers to remove the battery.
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.
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.
Hard-wired burglar alarms are all powered from the mains and connected via wires to the central panel. This means they don't need batteries.
