The Salt Lake City Fire Department will offer free batteries on Sunday with which residents can replace older batteries in their smoke and carbon monoxide detectors.

On-duty firefighters will also assist residents in checking the detectors and replacing their batteries, according to a news release from the department.

The firefighters hope residents will adopt the habit of changing detector batteries when they change their clocks in relation to daylight-saving time. Properly working alarms save lives, they have said.

Energizer Battery is helping to sponsor the effort.

The free batteries can be obtained between 8 a.m. and 5 p.m. at 315 E. 200 South, according to department public information officer Scott Freitag.
