  • Batteries are bounded by more predictable chemistry more so than something like the breakdown of a mechanical based trigger waiting for rust or decomposition. Chemistry makes it easier to model and predict. If you’ve got a 1Ah battery and it consumes x watt hours per hour, then it takes y days to burn through. Tolerances that cause the battery to have slightly more or less capacity or component power consumption will likely be <5%, thus not radically different because nobody is timing this to the minute.
