Change replaceable alarm batteries
Check whether each alarm has a replaceable battery or a sealed long-life battery.
Why it matters
Fresh batteries support reliable alarm operation.
Steps
- Check whether each alarm has a replaceable battery or a sealed long-life battery.
- Replace user-replaceable batteries annually with the type specified by the manufacturer, then test.
- Do not open sealed ten-year batteries. Replace the alarm when its instructions or end-of-life warning require it.
How often should I change replaceable alarm batteries?
Yearly is the planning default. Follow your equipment instructions and act sooner on a fault.
