Thanks blueliner for your comments and suggestions.

Can I ask you a question about changing batteries in smoke detectors? Well, I guess I will....

All the smoke detectors in my house are "chained" together (if one alarms they all do) and they are powered both by AC and have batteries for backup. I have noticed that the 9 VDC batteries last for years before I start getting a low battery chirp alarm. I assume that is because AC power is primary & the battery is for backup only. Assuming what I just stated is really correct; is it safe to go for long periods of time before replacing the batteries? I image most newer homes have smoke detector systems like mine.
