Alarm batteries are important for the operation of a burglar alarm system. They provide power to the sensors that detect intrusion, and they also provide power to the siren that alerts people of a break-in. Alarm batteries need to be replaced about once a year, so it is important to have some on hand at all times.
6v and 12v sealed lead acid burglar alarm batteries are perfect for home security systems because they are right size for burglar alarms and fire alarms. They also have a long shelf life, so you can stock up on them without worrying about them going bad before you need them.
