Good UPS that keeps my stuff working during an outage but has defective self-test. (2026 update)
Overall good UPS. I have purchased several of the same models. I use them for my computers and also my home theater system (amp, TV, PS5, subwoofer), and other electronics.However, all my APC units have the same defect in the self-testing mode or during a power outage at the house. Although, the defect during self-test is infrequent. Sometimes during self-test, unexpectedly the unit's alarm starts making a racket. I look at the display panel icon which indicates the battery is completely depleted. The first time this happened, I turned off everything connected to the UPS because I thought it would suddenly cut the power to them because the UPS thinks the battery was dead. The same issue could happen if there is a power outage at my house and the UPS switches to the battery power. After, I unplugged the UPS from the wall and cycled the power button off and on, the mysterious "problem" with the "failed" battery was self-corrected. The battery icon then showed it was fully charged: it had gone from full discharge to fully charged in an instant!Now that I know about this defect, when the alarm goes off and the panel indicates the battery is dead: I mute the alarm and leave my equipment on that is connected to the UPS. (There is no a power outage at my house.) It is a false alarm. In about 24 hours, the UPS mysteriously corrects itself and behaves normally. I can disconnect it from the wall socket and my stuff works fine and the battery level shows that it is fully charged but of course starts to show the remaining time left to depletion.UPDATE: June 2026All of my APC UPS units have stopped functioning properly after about five years of use. I tested each one by swapping batteries, and the results showed either weak batteries or failure in the UPS hardware itself. For the APC units that still appear to operate, I chose not to purchase new OEM batteries.Instead, I invested in the GOLDENMATE 1000VA/800W Lithium UPS Battery Backup and Surge Protector, and it has proven to be a clear improvement over the older sealed lead‑acid APC models. When I pull the power plug from the wall mains to simulate a power outage, the GOLDENMATE provides noticeably longer runtime and keeps my equipment powered flawlessly. The APC units—when they were still functioning correctly—could do the same, but for a shorter period. The GOLDENMATE is also roughly half the weight of the APC SLA‑based units, which makes handling and placement easier. I hope this modern Lithium Iron Phosphate battery pack UPS will last longer and be less trouble‑prone than the APC brand.Ver másVer menos
