Query: Good until it won't accept new batteries

These networked alarms are cool, and a great concept, but one of my three units recently began to beep for a battery replacement, and no batteries that I put in (brand new Duracells included) will satisfy it; it keeps on beeping.I will try to contact the company for support (one year old), and see what happens.
