load tested at 550+ watts , worked good the Replacement battery is APCRBC164 , however , new BE1050G3 units ship with Leoch 9.0 AH battery oder chemical smell from ups and battery has significantly reduced in these couple of weeks . the Battery was fully plugged in during shipping . ( very surprised to see that ) the unit was powered off, but still energized with the connected battery. APC support confirmed to me , Leoch 9.0 AH is the correct shipped battery . APC support suggested that this BE1050G3 had been powered up at\from amazon shipper ( amazon ) before shipping and that is why the battery was plugged in during shipping . ( shipper forgot to unplug it ? ) Battery measured 12.87 volts when i removed the bottom cover . The relays sound good during power on and Load test . adjusted the trip voltage to 96 to 136 vac window , Amber . ( default is Red 92 to 139 ) paper manual included. do NOT expect your BE900G3 and BE1050G3 ( most likely the entire BE series ) to come with an APC battery ,... it will NOT . they are coming with a Leoch battery same battery as the BE900G3 comes with . My guess is , this Leoch 9 AH battery is HR, High Rate to reach 540 and 600 watts . because a GP General Purspose 12 AH battery can reach about 500 watts for 5 minutes ,... csb GP 12120 . it might be able to reach 600 watts for 2 minutes, but csb GP12120 battery is physically larger( wider ) If BE1050G3 proves to be as good as APC 450 VA ups have been , than BE1050G3 will be a winner . comes with PowerChute and USB cable, Printer to Type A . haven't used it . noted: there is a chemical smell with this APC BE1050G3 ups . not burnt ,... just a chemical smell . It was like that Out Of Box . i think smell is coming from Leoch battery. ( the battery works, but i already replaced battery with a csb brand battery ) it might be the plastic case of the battery that smells ? ,... no sulfer oders . UPS's Battery Goal : BE1050G3 has 2 minute run-time out of box . but as battery decreases in capacity, in a couple of years the run-time might reduce to 1.5 min ,... 1 min ,... 30 seconds. to have 2 minute run-time at battery End Of Life , a larger battery will be needed to reach this goal . csb UPS 12580 battery is rated 4 minutes at 600 watts when new . csb UPS 12580 physically fits both BE1050G3 BE900G3 . ( substitute battery brands might not have same capacity as csb UPS 12580 )

Works flawlessly, have always purchased UPC branded UPC for work and home. Used to be IT procurement manager for large companies and we always purchased UPC branded UPS's. I use this one to plug the following items into it: IP Gateway, 8 port Smart router, EERO Device and a NVME NAS This provides excellent surge protection and provides a few minutes of network uptime if power is lost.

Remember the following details about the UPS: The UPS arrived securely packaged, and the setup was quick and easy. After running some tests, I discovered that it can keep my PC and monitor running for about 14 minutes, providing ample time to save any work and safely shut down my computer. The only downside I can think of is that there may be spacing issues for certain plugs that require extra space. Key features to note: - 1050VA/600W power capacity - 8 total NEMA 5-15R outlets: 6 for battery backup and surge protection, 2 for surge protection only - 2 USB charging ports (Type A and C) - ENERGY STAR Compliant for efficiency - User-replaceable battery - Wall-mountable design - 3-year warranty and $75,000 equipment protection policy - LED indicators and audible alarms for status updates

Caught this on sale for $124 and it is a 950VA. Good deal and a reliable brand. I normally keep a unit for 6 yrs before recycling. Replacing the batteries 2 or maybe 3 times. Sometimes it makes sense to replace in 4 yrs but I have never had a UPS fail on me. Batteries usually get weak, but are easy to change out

We bought this for our TV after a power outage fried out other TV. We get power outages every time there's a really bad storm (so about an average of 5 times a year). And I've had the power go out and the TV stayed on long enough for me to safely power off the TV and the PS5. I know it's not cheap, but it's worth not losing your valuable electronics.

I like(d) this product. I've bought four of the APC Back-UPS of varying capacity (2 x BE850xx). They work great for docking station, monitors, and router(s). My issue is that the last one I purchased (last month) didn't work. Problem Description: the power light blinks green 16 times and then goes dark and the continuous tone starts and does not stop until I turn the unit off When I tried to return it, there is no "Return Items" option in "Orders" but there is a button for "Get Product Support". I went through all the options: "Troubleshoot on your own", "Get help from Amazon", and "Contact the manufacturer" with no satisfactory resolution. "Troubleshoot on your own" - I went through all the steps (e.g., charging for 24 hours, Brain Dead Reset, etc.) "Get help from Amazon" - concluded that persistent overload condition meant I needed to replace the battery; Amazon gave me a credit for cost of replacement battery. I was happy but after replacing the battery the problem remained. "Contact the manufacturer" - I was told "Upon checking, your unit was manufactured on year 2017, it is now 7 years old...life expectancy of the UPS is 7 to 10 years and for its battery it has life expectancy of 3 to 5 years." Then he goes on to try and sell me a model BR1500MS2. In summary, this model is an older model so it'll be more risk and less reliable. I think it is worth spending another $80-$100 because you are essentially buying time - more time to get use out of the product.
