Smoke detectors just do these things; its part of life. You need to replace them at least every 7 years. If it lasts 5, don't worry about it; just replace it. They're like $20. I don't bother with the hard wired variety because the connector won't always fit the new model and the wiring has to be re-terminated anyway, so I just pop in a new battery powered model every 5 years or so. And date the damn thing on the outside cover so you can see when you replaced it. Also, I like to replace one every year so not all of them go bad at the same time.
BTW, you seem to have a lot of difficulty determining when something is "hot". You know you can buy a voltage tester at any hardware store for like $7. They're safe and simple to use. Perfect for the guy who doesn't know when he's turning off the correct breaker. Little hint: label your circuit panel or keep a drawing with notes.
