Q: Is there any type of guarantee from APC if my computer gets fried by a surge?

A: Nope. APC says LOTS of things when they are trying to separate you from your money. But when it comes right down to it (try filing a claim) they will ask you to PROVE that your device was plugged into their UPS when it was fried. Then you will have to send photos of all the parts showing how much POWER they use. And you will have to add up all the watts or Volt-Amps and prove that your device did not overpower their junky little UPS. My brand new APC Back-UPS 450 was not capable of powering my tiny little cable box. I am NOT holding my breath for remuneration...

Q: Whats the duration of the backup in hours ?

A: Thank you for your inquiry. The amount of runtime available will depend on the size of the load attached. Please refer to the attached brochure for runtime information for typical loads. http://www.apcmedia.com/salestools/JSIE-AD7S69/JSIE-AD7S69_R0_EN.pdf?sdirect=true

Q: Will this unit run a 1/2 horsepower garage door opener for a couple of UP/DOWN cycles?

A: 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.

Q: Does the battery recharge and last a lifetime? If not - is it replaceable? Last APC unit the actual battery died

A: Thank you for your inquiry. The BN450M will recharge its battery. The normal life of the battery will be anywhere from 3-4 years, depending on battery usage, load percentage and operating environment. The batteries in the BN450M are not user replaceable.

Q: Could a device like this be used to power a CPAP/BiPAP or AutoPap during power outage? (6-8 hours)

A: I have my BiPAP plugged into this. Not sure how long it will power the CPAP/BiPAP. Since I have had mine plugged in we've only lost power for a total of 10 minutes while using my BiPAP.

Q: Will it auto shut off an iMac when power goes out? Is the software and hardware fully compatible with Macs?

A: Thank you for your inquiry. Unfortunately this unit will not provide a graceful shutdown of your system. It designed primarily to be used with smaller equipment like a modem and router. If you wanted the UPS to trigger a graceful shutdown than you would need to go with our BE600M1 instead. You would then connect the USB cable that comes with the UPS from the Mac to the UPS. You can use the embedded energy saving features of the Mac OS to provide a graceful shutdown of the system.

Q: Is there a chart that can tell me how long the UPS will last based on power consumption?

A: Thank you for your interest in our products. Here is a link for a runtime chart. https://www.apc.com/us/en/products-runtime-graph/BN450MNW/APC-Back-UPS-Connect-450VA-120V-6-NEMA-outlets-2-surge-

Q: Could I use this on a power recliner to get me back to sitting position to get out of during lights out.

A: In a word, yes. My power recliners have a built in battery pack, you might check to see if yours does and if so do those batteries need replacing, but yes, the ups should provide sufficient power to get you “declined”.
