I finally read the fine print on a panel's battery backup specs

I was wiring up a new system in a house near Raleigh last week and noticed the backup battery on the panel was rated for 24 hours. But when I dug into the install manual, it said that's only with zero alarms, zero communications, and at 77 degrees. Run one cellular call or have a zone trip, and that time drops to maybe 6 hours. I had no idea the ratings were that far off from real-world use. Makes me wonder how many of my previous systems left people in the dark way sooner than I thought. Has anyone else found a product spec that didn't match what it actually does on site?

Oh GOOD, so their "24 hours" is basically a perfect fairytale scenario. I guess my house catching on fire counts as "normal conditions" then? Classic.

Well that reminds me of when my oven said self-cleaning but just smoked up the whole house for hours.
