Smart-UPS 1500VA/900W Line Interactive UPS with SmartConnect, SMC1500C

I last bought this UPS in December of 2018 and the battery is finally dead. I found out when we had another power glitch and the UPS didn't keep my computer powered on. It's now August 2026, so I had this thing running and working for 8 years without issue until the other day. We have quite a lot of power issues here and I've heard it click on quite a few times while I was working. I have nothing bad to say about this UPS.

Arrived defective. My IT people advised me to send it back, which I did. That was a major hassle because it contains a battery and could not be returned, but the seller quickly responded and sent an RMA and return label and it went back. My IT people told me it is a good product when it works right and recommended that I buy it again. So I did, but the price went up by $16. Not happy, but I have not given it one star because they were quick to send the return instructions. I will try again and hope for better luck this time. It is intended to protect a server. I like the fact that my IT experts can monitor it without physically coming in. I suppose this is a back door into my system, but I find it very useful. Hopefully the next one will work properly. I will update this after the new one is installed. ADDENDUM: This is a story of 5-star customer support. The product is good. I am not an expert and I do not have much to say about this product, except that it was recommended by my IT experts. The product was ordered on August 17 and arrived defective on September 1. Amazon currently takes about 2 weeks to deliver this item. One feature is that it can be connected to an outside IT monitoring service, and this did not work. So I went to Amazon to start a return. Amazon said that this product was not eligible for a return. What? $450 product and I could not return it? Was I stuck with a defective product? So, through Amazon, I found a way to contact the seller. Within an hour they issued an RMA and instructions for a return. We followed the instructions and returned it. I commented that I would like a replacement, but did not receive any confirmation that I would get a replacement. So I assumed I would get a refund. My IT experts still said that this was a good product and to order it again. It was highly recommended to protect my expensive server and we were seeing power outages due to unusual 112F high temperatures. So, on September 3rd I went to Amazon and re-ordered the same item again. I was disappointed to see that the price had increased. Within a short time the new Smart UPS arrived. The IT experts installed it and said that it was working properly with no problems. I waited a few days and saw no refund. So I sent an email to the seller to ask when I would get my refund. They replied quickly to tell me that they had sent a replacement and that there was no refund. They sent the tracking number to prove it. I researched the tracking number and found that we had received and installed the replacement, and that the new Amazon order was still on its way. The seller had shipped the replacement the day after they issued the RMA, and before they had actually received my return! So, now I realized that I was going to have 2 of these and I only wanted one! The seller told us to refuse delivery when the 2nd one came. It has not arrived yet (Sept 22). So, I am hoping that the seller has managed to turn the delivery in progress around. The seller has been amazing with quick replies to my emails and prompt service throughout this episode. I highly recommend them. 5-star recommendation.

EXCELLENT PRODUCT FOR 900W

Excellent UPS. Fit my needs perfectly

I've used APC products for over 20 years and I have gradually watched both the quality and capacity of these devices decline over the years. It's a shame really because the more they try to "improve" by adding unnecessary features the more they lose the core features which made these both extremely reliable mission-critical units. in the 1st place are capacity and reliability. sadly that reliability and bulletproof operation is in my opinion no longer a viable feature of these units. As I sit here writing this review I just experienced a power fluctuation (dropout) and the unit not only did not recover quickly enough but even the front panel began flickering with the fluctuation and my monitors went black. After rebooting I finished writing this review. I have some much older APC units which would have never behaved like this. It sad really that companies who produce quality equipment suffer from what I can only consider bad marketing decisions affecting quality in the end.

Haven't had a power outage yet but I've been using it for a couple of weeks now and so far so good. I didn't use the app I just plugged my computer and internet equipment into it and just use the front panel for info. I don't see a need for an app for my application. Mainly it's a backup for my modem, router and Synology media server.

I have two of these. One powers my two Linux servers, cable modem, router, Ethernet switches, etc. in my basement. The other powers my "everyday" Windows PC in my bedroom, as well as my bedside clock and my CPAP machine. I bought the second one after a power glitch killed my unprotected CPAP machine. Now my replacement CPAP machine is protected from surges and will keep running even when my utility power fails. I'll never go back!

DO NOT BUY IT! It worked for barely 8 months . We had a power outage, it worked for 2 hours and never recharged again. We requested product assistance and since it was after 6 months company selling it told us they would provide assistance as long as we paid for shipping. We paid $150 to ship it back and we never received feedback. It is a very expensive product to have such a short shelf life life. Terrible quality.

Over the years, I've bought six of these exact same APC UPS model. So far, none of these has required battery replacement, but has saved various computer equipment from power failures. I'm likely to buy another one of these in the near future.

llego empacado bien y mi cpu no se apaga en apagones lo cual puedo guardar informacion y no perderla lo recomiendo

Fácil instalación, confiable. Excelente producto

APC is solid stuff. Good build. Worked for job it was purchased for.

Use this in conjunction with my pellet stove in case of power outage. Works great. Will run it for 3 1/2 hours. Peace of mind if power goes out while we are asleep. I have generator back up in my house but its a manual transfer switch with a 9000w genny that I have to go and start. This thing just instantly switched on with out shutting down my stove. For people's information my stove will only run with pure sine wave. Modified does not work. This thing did what it advertised
