I changed the batteries in all my smoke/CO detectors to 10-year lithium batteries.
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.
Interesting fact I learned when replacing detectors is that small humans (i.e. toddlers) are more likely to wake up and respond to human voices/words.
There are detectors, for example, that say “Fire” (in English-speaking countries, of course). And kids are statistically more likely to wake up and respond to the smoke detector alert than the brain-piercing, ear-splitting buzzers that are more standard.
I put the above ones in bedrooms and the horrible, deafening ones in hallways and common areas. I also went the 10yr lithium battery route. Had to search online to order these, because they’re not generally available at retail stores.
