When should the batteries in smoke detectors be replaced?

• A. Every two years
• B. Every six months
• C. At least once a year
• D. Only when they die

Answer: (C)

The batteries in smoke detectors should be replaced at least once a year to ensure that the device operates effectively and can reliably alert occupants in the event of a fire. Annual battery replacement is part of routine maintenance that helps to prevent malfunction due to depleted batteries. While some smoke detectors may have a battery life of around two years, it is advisable to replace them every year, particularly for those that use 9-volt lithium batteries. Additionally, many fire safety organizations recommend monthly testing of smoke detectors and replacing batteries annually as a precaution. Choosing to replace batteries only when they die could lead to situations where smoke detectors are non-functional when needed most, which is a critical safety concern. Regular maintenance through yearly replacement ensures that the detectors maintain their ability to respond to smoke and fire, enhancing overall safety in living environments.
