It is essential that a smoke alarm battery is working at all times, especially if it a battery only model with no mains supply. After all, a life could depend on it.
We stock a 9V Lithium-Manganese Dioxide Non-Rechargeable battery, which is actually warranted to last for ten years. It attaches to the appliance with a standard Ni-plated miniature snap fitting.
Compatible with Other Alarm Types
This smoke alarm battery is also ideal for other types of alarm, such as Emergency exit alarms, Carbon monoxide alarms, Flood alarms, Door/window alarms, Electronic entry systems, Wireless security keypads, Home security devices, Panic buttons and Pet containment systems.
Use in Any Appliance
Although specifically designed for smoke alarms, where the relatively high price is worth paying to ensure the safety and security benefits of the alarm are maintained, it can be used in any appliance with a low power draw. Because it lasts so long it needs replacing less often so you can fit it and forget it in appliances such as Memory backup (e.g. clock radios, telephones, etc.) Digital scales, Baby monitors, Passive infrared detectors and Garage door openers.
