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.

    I also did this but then I started to get quite a lot of false alarms, turns out the lithium ones cause issues with the detectors while alkaline had no issue.

      That would highly depend on the particular device and battery used. Electronics are designed to work within a voltage range because voltage often fluctuates, with both AC and DC. Some electronics can be more sensitive and require a more narrow voltage range or have a more stable range and some power sources can vary their range more and have a higher rate of fluctuation.
