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

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.

Arrived quickly, well packaged, no complaints at all. Compact model, has been redesigned from when I last looked at these units. Connecting the battery for setup was a breeze. Simply flip over, and open the bottom flap. The battery is actually two batteries joined. They have two large stickers on either side, one red one green, that each have two tabs on them that you use to pull the battery out, flip it over so the green sticker is showing upwards, which then lines up the built in connector and slip it back into the unit, replace the bottom flap. Viola ! Seems to take a little longer than I remember to initialize, but that is no big deal for me. Comes with a testing report, dated 7/2025. Battery was charged to around 55% so I left it overnight on charge before connecting anything to it. Will report back if there are problems, but as of right now, unit is happily charging, no issues.

This is a physically large unit and it will handle quite a few items plugged into it. I've had no problems with it. It supports a desktop computer, a laser printer and two 3D printers without any issues.

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.

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.
