Every month, we put an industry question to one of our own engineers. This month's question comes up more than almost any other:
"If our UPS is still 'working,' why should we replace it before it fails?"
Our engineer answered: "A UPS rarely gives you a clean warning before it fails. As batteries and components age, failure modes get less predictable, not more. You might see longer runtimes on self-tests, or none at all, right up until a real event exposes the weak point. The systems these units protect, like a CT scanner in a live clinical environment, don't have a grace period. By the time a unit is showing obvious symptoms, you've usually already lost the safe window to plan a replacement without pressure. The real question isn't 'is it still working,' it's 'do we control the timeline, or does the equipment?'"
If you're not sure where your own UPS sits on that timeline, that's exactly the kind of assessment we do every day.
