Question About Nighthawk Carbon Monoxide Alarm KN-COPP-3
Battery alarm goes off....

Detector sounds off LB (Low Battery) even after installing a new battery after 4 weeks of use. I couldn't fix this detector so I replaced with another detector. This unit is supposed to have a 5 year warranty. Where do I send it for replacement.
