Nest Battery smokes alarms have an APP to tell you what is happening with you smoke alarm in real time
Nest Smoke alarms
Nest smoke uses Ultimate lithium batteries (L91) and is locally available. They need 3AA batteries for back up and do not require alkaline batteries because they would drain them. The battery model comes with 6AA batteries, and the wired requires 3AA batteries that are meant for backup in case power goes off. The Nest smoke alarms should be installed on the ceiling or the wall. Nest alarms are designed to alert you through a friendly voice when there are smoke or CO detectors in your homes. It can detect and tell where there is danger through the aid of its spectrum sensor. The CO detector the carbon monoxide and it’s able to alert you on the phone and where the CO has been detected. When there is less smoke through the Nest application, you can silence the alarm. At night it lights when you walk under it. The Nest smoke alarm and CO detector have a lifespan of about a decade, and therefore your family has assured protection and appropriate use of the batteries.

TYPES OF ALARMS
There are mainly four types of smoke alarm currently on the market – ionisation, optical (also described as photo electronic), heat and combined.
IONIZATION
These are the cheapest and cost very little to purchase. They are very sensitive to small particles of smoke produced by fast flaming fires, such as paper and wood, and will detect this type of fire before the smoke gets too thick. They are marginally less sensitive to slow burning and smouldering fires which give off larger quantities of smoke before flaming occurs. They can also be too over-sensitive near kitchens.
OPTICAL
These are more expensive but more effective at detecting larger particles of smoke produced by slow-burning fires, such as smouldering foam-filled upholstery and overheated PVC wiring. They are marginally less sensitive to fast flaming fires. Optical alarms can be installed near (not in) kitchens, as they are less likely than ionisation alarms to go off when toast is burned.
COMBINED SMOKE & CARBON MONOXIDE ALARM
Alarms that combine both smoke detection and CO alarm protection in one ceiling-mounted unit. This reduces costs and takes up less of your living space.
COMBINED OPTICAL SMOKE & HEAT ALARMS
These are more expensive but more effective at detecting larger particles of smoke produced by slow-burning fires, such as smouldering foam-filled upholstery and overheated PVC wiring. They are marginally less sensitive to fast flaming fires. Optical alarms can be installed near (not in) kitchens, as they are less likely than ionisation alarms to go off when toast is burned.
HEAT ALARMS
They detect the increase in temperature from a fire and are insensitive to smoke. They can therefore be installed in kitchens. They only cover a relatively small area of a room, so potentially several heat alarms need to be installed in a large kitchen.
