FAQ

Which battery does my smoke alarm use?

Check the label on the back of the alarm or the battery compartment. Some alarms have a sealed 10-year battery and are replaced as a whole unit.

Are batteries shipped by ground only?

Lithium batteries have carrier shipping rules. We will confirm the shipping method when we quote.
