s about UPS
Purchased a CyberPower 1500 VA UPS some time ago. The main goal was to have a backup power source for my XPS 15 9550 laptop during occasional outages in my area. Typically, I connect my laptop, monitors, modem/router, and other devices to a surge protector. Usually, I don’t use the UPS much unless there’s an outage. When I bought it, I charged it for a while and it displayed around 410 minutes of runtime. It seemed reliable when nothing was connected. Recently, I noticed that even though it stayed plugged in, I rarely turned it on or powered it up. I’d charge it briefly and then shut it off before using it again. Nowadays, I mostly leave it plugged in but inactive. I’ve heard that leaving a UPS running continuously can cause excessive electricity usage. To test its performance, I tried running my laptop through it. Initially, the runtime dropped from about 410 to 220 minutes when only my laptop charger was connected. After disconnecting the charger and unplugging the UPS, it shut down immediately. This suggests either the battery is degraded or the UPS itself might be faulty. The display shows full charge even without power, which is unusual. If I connect my laptop charger now, it starts charging again, but only if the UPS is properly charged. It seems the battery may not be holding a charge well, or the unit isn’t functioning correctly.
It's roughly five years since the battery was last used, which is typical for a UPS. My estimate suggests the battery may have failed. I've seen UPS units stop working after removal from power, but swapping in a fresh battery resolved the problem. A UPS isn't designed for this kind of application, and a battery bank would likely be more appropriate if you need reliable backup power.
UPS units aren't something you can simply turn on and off as needed. They work best when running continuously. I'm not sure what you mean by high electricity levels when left connected all the time, but the truth is that if it's not powered down during outages, its effectiveness drops. Still, EWizardy has a point — the battery is probably nearing the end of its lifespan and should be replaced easily.
