  While it’s important to replace your batteries regularly, it’s just as essential to choose the right type of battery. Here’s how to make sure your smoke detector’s battery lasts as long as possible: Choose the Right Battery for Long-Lasting Power Alkaline vs. LithiumFor longer-lasting performance, lithium batteries like CR123A are a great choice. They can last up to 5 years, while alkaline batteries typically last 1 year. If you want fewer battery changes, switch to a lithium battery for better longevity. Long Shelf LifeIf you purchase batteries in bulk, opt for lithium-ion batteries, which have a shelf life of up to 10 years. Store extra batteries in a cool, dry place to ensure they remain effective. Tips for Maintaining Your Smoke Alarm Regular Cleaning: Dust can interfere with the smoke alarm’s sensor, leading to false alarms or reduced performance. Clean your smoke alarm every few months with a vacuum or soft cloth. Monthly Testing: Test your smoke alarm by pressing the test button each month to ensure it’s working properly. Replace Batteries Annually: Even if the battery seems to work fine, it’s a good habit to replace the battery at least once a year to ensure safety. By taking these steps, you can extend the life of your smoke detector batteries and ensure your alarm remains reliable.
