FORT WORTH, Texas, March 8, 2013 /PRNewswire/ -- RadioShack Corporation (NYSE: RSH) encourages everyone to change the batteries in their smoke and carbon monoxide (CO) detectors when resetting clocks for Daylight Saving Time, which starts in most areas of the country on Sunday, March 10 at 2:00 a.m. "To keep your home and family safe, it's critical to change the batteries in your smoke and CO 2 detectors at least once a year," said eHow's Tech Editorial Director Dave Johnson. "We recommend changing these at the same time you reset your clocks for Daylight Saving Time. That way, it's easy to remember." Every home should have smoke detectors and CO monitors, but it's also important to remember they require some minor maintenance and don't last forever. In addition to replacing batteries in these important home safety tools at least once a year, batteries should also be changed anytime a detector emits a low-power warning. This usually sounds like a chirp that occurs once a minute. And if a smoke detector is more than 10 years old, the entire detector should be replaced. According to the U.S. Fire Administration (USFA), a working smoke alarm significantly increases one's chances of surviving a home fire, and it's estimated that one third of smoke alarms are not working, often due to worn-out batteries. To help combat this statistic and encourage consumers to take the simple step of changing batteries to ensure home safety, RadioShack is offering a buy one, get one free deal on Enercell 9V 4-pack alkaline batteries now through March 16, a perfect match for most smoke detectors. "Since joining RadioShack, I've learned a lot about home safety and disaster preparedness," said Amy Shineman, Director of Consumer and Product Marketing at RadioShack. "I am proud RadioShack provides a convenient place where our neighbors can find products—ranging from batteries and security systems to weather radios and flashlights—to help protect their homes and power through storms." In addition to changing the batteries in your smoke and CO detectors, now is also a convenient time to check the batteries in your weather preparedness kits and other safety appliances. A well-stocked weather safety kit should contain a flashlight, portable power for your electronics, an emergency radio, walkie-talkies, bottled water and dry goods. Additional alkaline batteries are always good to have on hand in case of emergency.
