But I've had it where replacing them also didn't seem to immediately kick in, so it was frustrating. Eventually they did recognize they had been changed.

But I swear, nashty, that if mine go off tonight, I'm going to blame it on you and I'll find your house and make sure yours go off every night for a week. OK. Just kidding. But I would blame it on you.
