Daylight Saving Time: When You Change Your Clocks, Change the Batteries in Your Smoke Detector March 4, 2018 Email March 11 is the beginning of Daylight Saving Time, which means we have to move the clocks forward an hour.

When you change your batteries, remember to recycle your old ones. Never throw batteries in the trash — they contain dangerous metals and corrosive chemicals that can leach into the environment. In Lincoln, we have two programs for battery recycling. The Battery Recycling Program is a drop-off program, and the Free Universal Waste Collection Program is a pick-up program.
