Today, I changed the batteries in all my smoke detectors. I noticed that the battery light in one was blinking. Instead of only replacing the one with a new normal 9v battery, I ordered a pack of 10-year lithium 9v batteries and replaced them all. Now I don’t have to worry about changing them for a handful of years.
Edit - Funnily enough, dinner put them to the test. I was going to test them tomorrow when the kiddo is at daycare.
Push the test button, of course. I find it helps make sure everyone wakes up on time.
I mean, Daylight Wasting Time is probably going to finally end this year, so what are you going to do next year?
