Can this maintain a small UPS battery that is 12v 9ah, at most it would power an LED light for 20 minutes once a week.

12 volts generating 5 watts is about .4 amps. So, it would take 9 amp-hours / .4 amps = 22.5 hours to fully charge the battery (in a perfect world, anyway). Or in other terms, your battery has a theoretical capacity of 108 watt-hours (12 volts x 9 amp-hours) and the panel charges it at 5 watt-hours per hour. This -should- meet your needs, but I have no idea how much juice your LED light takes. Once you determine that, you should be able to figure it out. Note that you do not want to discharge your UPS battery all the way as this reduces its life. So, you will really only have some fraction of that total energy available for regular use. 12 volts generating 5 watts is about .4 amps.

I believe it would work but Im not a %100 sure. I have powered mine with many different kinds of batteries. A 9volt works just fine for an hour or two.

No, it's not like other ups with easy battery access. For the price, you would replace the unit if the battery goes out.

It does not need additional supply, however, I would buy cheap UPS (from Costco) so that it can stay up for for few minutes.I would check the Amp requirement on your circuit as they do consume a bit more power.I am running 4 of them at my shop.Thanks

I used this in a UPS (uninterruptible power supply) for a computer. They battery is rarely activated, and the last one I got lasted over 5 years. I would check the VA and make sure its compatible with the equipment you are planning to use it with.

That's a good question to which I do not have the answer. What I can tell you is the battery has been in my UPS for about six months with no problems.

Sorry I really don't know if that would work. However I use a trickle charger for a car battery and use battery to power my trolling motor and the charge last about five hours of continuous use.

I installed a small UPS like you would use for a computer. Gives me about 90 minutes of full load run time. When in standby, it uses little or no energy, so it will get me through most short outages where it's not worth the effort of hooking up the generator.

I suppose so long as the UPS held enough power to run the system it would work but not sure you could get 10 minutes off an UPS as they heater will pull more juice than a computer. It is a very good heater though.

Yes. I use it to keep a small scissor lift battery powered up. stays plugged in 24 /7.

No, it is just a basic 1000W inverter. I think you are mistaking an inverter for a Universal Power Supply (UPS) that has a small battery in it to keep your electronics running for a short time in the case of a power outage.

I have not tested it for that length of time without power but I would think that it would. The unit uses very little power to run the time circuit and LED display.

I used this battery for APC UPS not for PA System.. maybe it will work also. I am not sure ....

Rajesh,The run time depends on the size of your battery not the inverter.Joe

Should work fine!, its a 12 amp hour battery, so if the light is 1 amp (i doubt it for a LED) then theoretically you would have 12 hr.

I agree with the other posts . You need Deep cycle batteries but you also can find power inverted made to accomplish this task the only question being capacity wattage and if it has pure sine wave out put as long as your load isn't more than what the inver can provide and battery has enough capacity & is of correct type then you should be fine . Never however modify or tinker with UPS and modify it beyond what the design say .

My guess would be YES, ABSOLUTELY. I run a 28" LED TV for 8 hours on a single charge. I'm not a scientist, but you can calculate how many watts of power are used: go here to this website -- https://www.batteryweb.com/pdf/inverter_battery_sizing_faq.pdf
