Home Alarm Battery


Most home alarm systems include a 24-hour stand-by rechargeable backup battery. This means if there is a power failure (which can happen regularly during winter storms) your home security system will still function. Having a reliable stand-by battery ensures the efficient operation of your home alarm system. After all, your house alarm system is only as strong as it's weakest link so don't overlook the importance of the battery.

 Usually when the stand-by  battery, that powers a house alarm in the event of a mains failure, deteriorates, an indication will normally be displayed on the control panel of the alarm system or on the remote keypad, if a keypad is installed. This is the early warning alert to  replace the battery before it deteriorates further and could possibly damage the control panel.


Can I replace a lower Amp Hour (AH) battery with a higher one?

Normally, as long as the battery that you are replacing is the same voltage,12V.dc, you can use a higher capacity (higher AH) battery than the original one.  The reverse is also true.  Using a battery with a high AH will maintain and operate the house alarm system, in the event of a mains failure, much longer than a battery with a low AH.  This feature is important if the power frequently goes out or is out for long periods of time.  However, the higher the AH is on a battery, the bigger (physically) it will be. Unfortunately this is not the case with the ASTEC Alarm Control Panel. The battery compartment in  the Astec Control Panel in limited in size an will only facilitate the  installation of the 12v. 2.1AH battery


Yuasa yucel 12v. 2.1AH battery is suitable for the following Astec Control Panels.

 Astec 49

 Astec 63

    The battery works fine and as expected. Only slight issue was with the website delivery status. It said it was still fulfilling the order when it arrived and I got a dispatch notice nearly 2 weeks after it arrived.
