When do I replace the smoke detector battery?
Batteries weaken with age and must be checked and replaced at regular intervals (usually every 6 months). Battery powered units that are listed by UL or FM will generate a beeping sound (usually at night when you are trying to sleep) to indicate when the batteries need to be replaced. Remember having a detector with dead batteries is the same as having no detector at all. There are newer smoke detectors out there that have batteries that last 10 years.
