How do I replace my carbon monoxide or combination alarms battery?

Changing the batteries
We recommend replacing the batteries in all of your alarms at least once a year, or any time the unit indicates the battery is low. The general rule is to replace the batteries when you change your clock for daylight savings time and / or when you switch your clock back. When the battery requires replacement, you must remove the old battery and replace it with the same battery type.
Locating the model number
NOTE: Our alarms have a variety of different battery installation procedures depending on the model number of your alarm.
To locate the model number on the alarm, perform the following steps:
1. Remove the alarm from the wall or ceiling.
NOTE: Most alarms are attached to a mounting plate and can be removed by turning the alarm counterclockwise.
2. Locate the model number on the back panel of the alarm.
NOTE: Once the model number and correct battery type have been identified, install the battery using the directions found in the user’s manual.
