Change smoke alarm battery.

Step by step here s how to change a smoke detector battery. Hi this video shows you how to change the battery in 5 different smoke alarms detectors and 1 carbon monoxide alarm. Gently pry the cover open or unclip the body of the detector from its base with a slight twisting motion. Be sure the battery is new so that it lasts the full ten year life expectancy of most home smoke detectors.

The general rule is to replace the battery twice a year. Once when you switch to daylight savings time and once when you switch back to daylight standard time. Replace the backup battery in a hard wire unit yearly whether it beeps or not. Generally most smoke detectors use a 9 volt battery for power though you should always follow the directions that came in your smoke detector manual.

The average smoke alarm battery life is one year but this time frame will vary depending on the type of alarm system you have in your home and the batteries you use to power it. Kidde recommends replacing the batteries in all of your alarms at least once a year or any time the unit indicates that the battery is low. Or set a calendar reminder for when to change your smoke alarm batteries. Inside you will find three main parts.

A good rule of thumb is to change it when the clocks change in the fall and spring. For most alarms the smoke detector battery change frequency is anywhere between six to twelve months.
