FREE: Smoke Detectors (x2)

Hoping someone can use these two Kidde smoke detectors which the manufacturer states are good until 2031. They also recommend annual battery replacement - the batteries in these will need replacement before the end of this year. Each detector takes two 9volt batteries. We’ve shifted over to combination CO/smoke units and because these two have at least five more useful years, we are looking to find a home where they could be valued. You pick up - high Quadra area. Thanks.
