You should refer to the product label found on the back of your alarm (or the user's manual) to identify which type, brand, and battery model is recommended for your specific alarm. Alarms require fresh and powerful batteries. Sometimes off-brand batteries, or those that have been sitting on the shelf for several years, will not be powerful enough and may cause your alarm to go into low-battery mode.
