Utilising FireAngel's Thermoptek thermally enhanced optical smoke sensor – the technology of choice for the UK's Fire and Rescue Service – the ST-623E is less prone to nuisance alarms caused by dust or cooking fumes and is quicker to detect smouldering fires than standard optical alarms. To aid evacuation in an emergency this product has an integrated extra-bright LED light which activates with the alarm to illuminate escape routes, making it a great choice for use in hallways or near stairs. For additional peace of mind FireAngel have also included Sleep Easy™ to silence low-battery chirps for 8 hours and Alarm Smart Silence™ so that it can still warn occupants of a real fire developing after silencing a nuisance alarm.

The 9V alkaline batteries and AA alkaline batteries generally last 12 to 18 months. Lithium batteries will usually last 5x longer than their alkaline counterparts, achieving around 5 years lifetime. Some lithium cells are also rechargeable, and when used in a mains-powered alarm may last for the entire functional lifespan of the alarm. Newer alarm models may also feature a "sealed" lithium battery. These batteries are specialist components which are designed to not be removed or need replacing by the user, and have been tested by the alarm manufacturer to ensure they last for the lifetime of the alarm.
Please note: the actual lifetime of your batteries depends on how often the alarms are tested or activated, as sounding the alarm draws more power than when the alarms are "waiting" to detect fire. You should also read your alarm's manual to make sure you only use the recommended types and brands of batteries, as failing to follow these instructions may cause the alarm to malfunction, not alerting you in the event of a fire, and might also invalidate the warranty.

A good product with a replaceable battery Fed up with smoke alarms that come with non replaceable batteries that only last half the time they are supposed to. This was a perfect find. Good value for money.
