    Good enough to ensure you can save your work

    Good enough to ensure you can save your work. I had two lap tops plugged in. Unit started beeping after about 20 mins. Beeps every minute after that until the battery completely dies out at about 30 mins. Hover you can mute the beeps. I wouldn’t bank on this to be able to cover you on a power outage to keep your modem and router going for an extensive period of time. If you are looking to cover a desktop in case of power outage to ensure you can save what you are doing, this will suffice. Unit is a bit bulky. Yes it has surge protection and battery but standard surge protectors separate battery pack would take up less space. If this had a longer battery life, I wouldn’t care about the bulkiness, however longevity is under whelming.

      Thank you for taking the time to review our UPS and taking the time to provide feedback about it. The runtime would depend on how much equipment is connected to it. This unit is one of our smallest UPSs as well. We do have larger UPSs if you need the additional runtime. We also have extended run units available in our SmartUPS line as well if you need additional runtime. If you need assistance in choosing an UPS with more runtime please do not hesitate to reach out an APCbySchneider sales member. We offer email and chat services through our support site.

    APC Battery backups are the best

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I have purchased two other of these APC units in the past and they do a marvelous job allowing you a good deal of time to finish and save your work in a blackout. I had one unit battery die on me after two years (battery life is not forever)and the Tech folks quickly issue me an RMA to get a,replacement unit. It arrived in two days and they pay for the returned defective unit. With a 3 year warranty on most of there UPS units you cant go wrong. Im going to Purchase another unit for my son's PC and monitor and printer. I highly recommend this unit.

    APC UPS

    This UPS replaced another APC UPS that had died after 6 years due to a battery failure. Best Buy had this one on sale for about the same price as a replacement battery. It seems to be working just fine.

    This product works very well. I was surprised at the number of surges this unit has detected since I connected my computer to it. Had APC UPS for years, love the brand, trust the product. definitely worth the $$, especially with deal of the day price.

    Works, but flawed design

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Short story: buy the 650. It has a replaceable battery. This one doesn't. Long story:This will run for 2 years, then the battery will wear out. The light will alternate red and green and the beeping won't stop until you turn it off. You can't power your devices when the battery is dead, even if it's plugged in, so it's a paperweight. Then you will discover the problem. The device is not made to be user-serviceable. You can't replace the battery. You can't throw it away, because it's illegal to dispose of a lead-acid battery in the trash. Places that take lead-acid batteries won't take the whole thing. You have to take the battery out yourself. Hope you have the tools. Don't just throw it away. The lead really does get into the water table.

    Utter waste

    If I could give this a zero stars I would. It went into alarm mode and quite working completely 11 days after I got it. It likely was a very old unit in Best Buy's stock or just defective.

    No User Replaceable Battery

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I've used APC back-ups for years and always been very satisfied. I'm sure this is a good product, too, but I was quite disappointed to discover that it does not have a user-replaceable battery like every other one I've ever owned. Looks like a throw-away in three to five years when the battery dies.

    Backup battery does not work

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I purchased this produce in November, but only recently have I experienced any power outages to see if it works. The first time, the unit did not back up the connected modem and router. I wasn't sure if I had connected something incorrectly, so I checked everything, and all seemed well. I just experienced another outage, but again, no backup. I've made sure that I connected the battery (Duh!), which I did. and made sure that the devices I want backed up are plugged in the correct outlets on the UPS. So, I'm reasonable sure the problem is not my fault. Obviously, though, if the unit doesn't back up my devices for even 10 seconds, that's not what I paid for. Right now, I'm extremely unhappy. Since there are so many good reviews, it may be that I just got a lemon, but still I can only review what I have and it doesn't do what it is supposed to do.

    Don’t buy APC brand...

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Bought this a few weeks ago, on sale for $40, to keep my cable box powered up during power fluctuations. THIS PIECE OF JUNK DOES NOT-NOT-NOT WORK. My lights flickered today. CLICK: cable box powers down. This thing can’t even keep the tiny electrical load of a 6-month old cable box running?!?! So the cable box tries to reboot, CLICK. Three more times the box can’t even fully reboot and the UPS fails to do it’s job. Also, the manual describes several scenarios of status light plus beep tone, but it DOES NOT DESCRIBE THE BLINK PATTERN I AM SEEING, NOR THE BEEP TONE!!!!! I am VERY frustrated and I will NEVER buy another APC product ever again. I am going to try CyberPower as I hear they are very good. NOTE: Earlier when I did a search for APC UPS half of the results on Google were for CyberPower products. Just now when i did a search for CyberPower UPS there were ZERO results for APC! I guess that should tell us all who NOT to use...

      Thank you for taking the time to review our UPS. I am sorry to hear about the issue you are facing with our UPS and any inconvenience it has caused. I would double check that that the cable box is plugged in the battery side of the UPS and not the surge only side. If the unit is plugged into the battery side I would try reboot unit the unit to see if the issue clears up on the unit. You can reset by disconnecting the power cable then the internal battery. After this you would want to hold the power button for around 10 seconds. You would then reverse the instructions to power on. If the issue still persists after this process please do not hesitate to reach out to an APCbySchneider support team since this unit would come with a 3 year manufactures warranty. We would be happy to assist you in resolving the issue. We offer email and chat services through our support site. APC

    Underpowered

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Cannot keep up even laser printer. Shuts down when printer is connected to battery powered outlet. No USB to connect to computer to shutdown computer when power is down. Very under powered and lowest entry battery backup. It will not keep your computer safe if power is down. Computer will be powered down unexpectedly, which might cause System disk failure.

      Thank you for taking the time to review our BN450M. We appreciate the feedback. We actually do not recommend connecting a laser printer to our Back-UPS for the exact reason you described. Unless it is mission critical to be able to print during a power failure, we recommend connecting a laser printer to a separate surge protector. APC

    Don't you love waking up in the middle of the night by an alarm that cannot be disabled? As if this thing is saying "Get up! Get up! APC needs more money!!" Another winning feature is the non-replaceable battery. Made a switch to CyberPower and never looked back.

    No capacity published?

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    There's something fishy with this UPS: Capacity- the most important spec of a UPS (or anything with a battery) is nowhere to be found. I guess it has very low capacity they don't want us to see. Pig in a poke...

      Thank you for taking the time to provide feedback about our UPS. The BN450MNW would support 255 watts of power connected to it. It would also have a 47 volt amp hour (Vah) rating. APC
