APC 1500VA Compact UPS Battery Backup & Surge Protector, Back-UPS Pro (BX1500M)

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.

Our office is in the countryside where there is no cellular service. We rely on WIFI calling since we have no land line. Combined with Starlink, this unit is a great asset. It keeps our internet service working and we can recharge our cellular phones and our laptop during a moderately extended power failure. So far, it has worked exactly as advertised. Installation is very easy and it comes with basic instructions if needed. There are more than enough outlets in the back for our needs including coax, RJ45, USB and data plugs. It has a small footprint and it maintains a proper temperature. Recommended.

I've used this ups for around 2 1/2 - 3 years and once I moved cross state I had to leave it behind due to the weight of it and being not as cost effective to ship across the us and ended up purchasing another one since it worked amazingly compared to the other ups's I've tried, gives you a buffer period between power flickers to not have your desktop pc completely shut off or a 5-15 minute window depending on your pc specs to power everything off safely in a full outage, I have a fairly beefy power hungry pc with a rtx 3080 and other high end parts and this is one of the few I've seen that can handle the wattage usage of my pc at this price point while still managing to keep my pc on during power flickers, also nice it has a side that's purely for surge protection and Ethernet surge protection, It's super important to have a solid Ethernet surge protector on your modem, had my previous 300$ 5 gigabit modem die to lightning hitting a tree in our front yard and having lightning travel up the copper coax line and frying it so make sure you're getting usage out of all of the features of this ups and save yourself money down the line with dead/fried components!

La batterie de secours fonctionne parfaitement. J'ai un serveur avec ses deux alimentation branché dessus (avec une consommation moyenne de 450w) j'ai régulièrement des micro coupures de courant, et cette batterie Tiens très bien. Je n'ai eu aucun problème avec. Actuellement il est affiché sur la batterie que la charge utilisé est en moyenne, et une autonomie de 16minutes.

Works well, easy to use, PC recognized it immediately. Nice display. Alarm will go off if too much power is connected to it. It has a battery and will keep your electronics on after your power goes out, it can then safely save and shut down your computer. It is large and heavy. It has a lot of power. It does not have a smell or speed.
