Batteries inside of stove/microwave/coffee machine/etc. with the sole purpose of keeping the time from resetting when it loses power.
You don’t even need that. My microwave is wifi connected but still can’t keep time. Instead of using NTP like any appliances or industrial control system in the last decade+, it syncs to your phone time though an app.
Wtf.
Nothing in my house is WiFi connected, other than computers and phones. It’s staying that way forever.
I’ve conditioned myself fully by this point to only use the clock on the stove as an indicator of whether my power has or has not gone out
How often does your power go out? Why can’t you be bothered to set the time every ~10 years that probably happens?
Personally, where I live now, my power has gone out in the last five years more often than the rest of my life combined. I’m in my mid 30s.
I guess you haven’t cleaned your microwave in 10 years or had to do any electrical maintenance in the kitchen.
I’ll have momentary power losses probably once or twice per quarter, depending on bad thunderstorms or nearby construction, things that happen worldwide and affect power grids indiscriminately.
I do set my stove clock, I just ironically find it more useful to not improve it in this ridiculously simple way because it’s a good indicator of whether my home has had a power outage. Lol
Computers have CMOS batteries. They are pretty cheap. I don’t know why they haven’t been added yet.
