I haven't tried but this is a very small battery. Very very small. There is a good chance it might try to open the garage door only to either burn up the APC or worse your garage door opener due to lack of amperes. When you have a load pulling more amps than a power supply can provide what generally happens is something gets smoked. If you were trying to get a portable way to open a garage door then I would get a large car battery, a 12v. power inverter (to convert the car battery to 120v AC.), and a cheap battery charger to refill the car battery. This will be more expensive but much safer and less chance of screwing up your garage door opener. Before you spec out and buy your 12v power inverter look on your garage door opener for input current or wattage. If it is displayed in wattage take the number and divide by 110, this will tell you how many amps it pulls out of your wall. It'll probably be arourd 2 to 6 amps or so (I've never messed with a garage door but there are other factors at play that I cannot estimate like how heavy your door is and how much of a counterbalance you have aiding the lift.). Use that amp rating when deciding on a power inverter and make sure your inverter is 30% stronger than necessary to avoid smoking components. Good luck. FYI. I have spent a couple years doing work in electronic prototyping.
Sorry, there was a problem. Please try again later.Hi Dave, Thank you for your inquiry. 1/2 horsepower is equal to approximately 372 watts. The BN450M is only rated for 255 watts. You would need something like the BE850M2 instead, which is rated for 450 watts.
Sorry, there was a problem. Please try again later.No, you need a Sine Wave type of UPS.
I would recommend:
Sorry, there was a problem. Please try again later.No, just tried it, may try a larger amp UPS someday soon, in the mean time ALL new and ALL rental properties in California are required to have built in battery back ups|||
Sorry, there was a problem. Please try again later.You need a larger back up unit , this one would probably move the door 3/4 of the way one time. If you have a incandescent bulb in it. I only use led bulbs which might get 1 full up or down cycle.
Sorry, there was a problem. Please try again later.IMHO - Yes, it should handle this garage door opener. I have a 1 1/2hp opener and it worked with mine (test). NOTE - Check your garage door manual - or the sticker on the motor for the 'wattage' or 'amperage' rating. Not going into detail - If your opener 'use' is more than '1.5A' or more than 150Watts - yea it should work for you. Just don't expect it to open and close more than 2 or 3 times if your power is out. Remember - Garage doors have a 'Emergency Release' handle. Pulling this you can push up the door to get out. Hope it helps - all IMHO.
