Very mixed feeling about this vidio ..... most half decent designers of equipment will attempt to balance there design components ... ie small battery, low output, low output time, light components ... if you have an item that is run flat out for couple of mins they'll cope. But if you then give it a battery that will let it last for hours .... may be the components won't. It like putting a turbo on your engine & then not up rating the brakes.
Why didn't you just plug in the ups into an inverter which would be hooked up the the deep cycle battery & in turn place a trickle charger such as a 2 amp to maintain it?
@Begbucks Because the ups needs a pure sine wave inverter to charge. The only ones I have are the regular square wave ones. Also I don't have the battery capacity to support my computer, even with a charger hooked up.
@1LongReaper Most ups systems will only last 15-20 min with a 50% load (like a desktop and monitor). If it is only lasting 20 min with a laptop or wireless router then the battery could be bad.......All depends on the size of the ups though. I'm not sure of your battery configuration, but it sounds like you have a 12 volt ups. If your battery is reaching 13 volts, that is right about the maximum cutoff point. if it goes 14 or higher the battery will vent and be destroyed.
Cool... The fan is a must as i said them cheap ups arent meant to run long. I had one catch fire running it to hard so your not the only smart enought to upgrade them tiny batteries.. Works awsome on a continuous driven ups..
@simbalage22 I have long since upgraded to a line interactive ups rated for 750 va.....I never attach more than the rated load as to prevent the issue you had with fire. I also have a fan cooled ups made by xantrex. It has a 40 amp hour capacity, but still uses modified sine wave for output. As long as you aren't running an expensive psu the output will work fine.
Awsome video. I want to do the exact same thing... hook up to 12 volt deep cycle battery that is charged by solar. But how do you isolate /separate /disconnect the charging function that is built-in to the UPS? I don't want to cause some kind of malfunction in the circuitry of the UPS, by having an external charging source in addition to the built-in charging source. Aside from this concern, I really just want to make better use of my solar application, no AC input to charge.
@conquista100 I have no idea to be honest, I simply just made a separate solar system with that battery shortly after this video. I'm sure it can be done (you can probably check forums on the subject).
Also more expensive ups are pure sinewav and run like an inverter so they always are using the battery and charging and DOESNT need to switch to battery when the power fails, the cheap ones like in this video switch when it detects there is no ac power
INCORRECT.. Ups fail because the batteries OVERCHARGE.. its actually a good idea to run in off the battery every 6 months. Basic ups are modified sine wave and are intended to run for a short time and at the Ah battery supplied with it.. In theory a larger battery WILL work, but the ups isnt ment to be ran for the length the bigger battery will allow... also the charging circuit will never charge the big battery to its full capacity
@legendmove I have moved this battery to work with a solar system.....The battery is vented into a large room with two windows (they're opened about 2 times per day) so a venting system is not necessary. In fact I've had the same battery in that room for a year with the solar and not one problem with gas buildup or corrosion.
Hi, I want to link a 12 volt battery & a 6 volt battery together. I already have a 12v 100AH Deep Cycle, & understand the AH rating needs to be the same, but I want to use them together at under 18 volts. So I would need to have the 12v @ about 11.5 & the 6 volt @ about 5.5. I only need a few 3 second bursts of use. Would the batteries still give a strong current? Or would they perform weaker at those voltages?
please fix those wires up... that looks abit dodgy you know... its not the highest quality grade wires and joints there twisting them together with electrical tape. Thats not the way to go man.
@37474748 It was dissembled and turned back into a normal ups a month later. I took the deep cycle battery and built a solar generator with it.....All the wiring has been upgraded to 8 gauge and electrical connections are now made with ring terminals, F2 terminals and wire nuts.
I also have a 30 amp fuse between the battery and solar panel, just before the panel enters the charge controller.....This ups setup was made to work for only a month or so, until I bough solar panels.
@37474748 It works pretty well, I run lights, fans and a small lcd tv every day. It works off of 70 watts of solar and is assisted by 2 smaller systems (20 watts solar each).
You could probably get a small panel in your window (depends on the rules at your complex). I have seen a few people with the flexible cigs panels in their apartment windows.
@sirmasterpimp yeah problem is that my pc draws almost 1.5kilowatts of power. and my server about 500watts or so. Is there an way to make that kind of power free?
That is not a true deep cycle battery, that is a hybrid deep cycle/starting, you can NOT drain that battery down to 20% without damaging it. You can drain it down farther then a typical starting battery but not as far as a true deep cycle.
@DBLDREW I know, I would really like a battery bank consisting of large 2 volt cells (300 + lbs each) running in a series string for 12 volts, but those cost thousands of dollars. The next step would be two trojan 6 volt golf cart batteries wired in series, but again the cost factor. These hybrid batteries last about 5-7 years if you treat them right, so it will do for now until I can afford a true deep cycle. The hybrid batteries are still better than a normal car battery (much thicker plates).
@sirmasterpimp the point is that you can get a true deep cell "trolling" battery for the same cost as you could a hybrid battery. you can pick up a 75AH for about $58 or a 110AH for about $70. from walmart. you got a battery that will allow you to start a motor but sacrificed being able to dran the battery down farther. Considering your project doesn't have an engine to start you would be better off with a true deep cell.
@DBLDREW I had to go hybrid because the ups normally works off of agm batteries. Under load a deep cycle battery's voltage drops too quickly for the ups to stay on for more than 2 minutes. The hybrid isn't much better, but thanks to the extra cranking energy the ups runs for at least an hour before the low voltage alarm comes on. A Deep cycle flooded battery is fully charged at 12.7 volts while an agm battery is 13 - 13.5 volts when the ups trips. AGM maintains a higher voltage under load too.
@DBLDREW I may go for one of those 75 ah batteries later on (for my solar system) if I still don't have enough cash for a trojan. Thanks for the advice!
I have a PCM 650VA with ~ 7amp 12v batt, i tried to attach a car 40amp battery but the ups will give me bad battery beep and shutdown :S... deep cycle marine batteries are very expensive. is there any way i can do this with a car battery?
@snake1250 Your ups is probably setup to only use AGM / SLA batteries. The problem is that a car battery gives off less voltage than an sla battery (car bat = 12.7 - sla = over 13.0). They charge the same, but when the power goes out the car battery will drop to around 12.5 volts while the sla will stay in the low 13's high 12's. When you car battery operate the ups and drops to the mid to low 12's (almost immediately) the ups will shut off. You can still get a deep cycle agm battery for cheap..
@sirmasterpimp I am currently working with a 35 amp hour AGM battery that only cost me $50. It actually preforms better (with the ups) than the huge flooded deep cycle battery in this video because of the voltage issues. You can try ebay and search around for good prices or try a local computer store. You also might not want to use a car battery, due to their thin lead plates. If you drain a car battery under 12 volts (you ups will), it will be permanently damaged.
I have and Old APC 670 W 24V UPS with two Built in worn out batteries. I want to add 120 AH car battery so that i could use it during load shedding hours. Will the built in charger be able to charge this High Capacity Battery ?
@UTubeStream Your going to be using two batteries in series right ? You can't use just one or it will probably ruin the battery. If you are using two, then yes the built in charger will charge the battery, slowly. The built in charger is no different from a trickle charger, so it will charge the battery up in a day or so (depending on charge state) and will maintain it with no problems
is there a way to hack the diode of an APC UPS so I can increase the Output Power Capacity? I have an APC BACK-UPS CS 650VA 230V ASEAN which is 400 Watts. The battery is dead now and I want to boost it up to 800 Watts so I don't have to buy a new UPS.
Not really sure, since I haven't exactly tried that yet, but sounds dangerous. Doubling the wattage will put severe stress on all the components and will almost certainly cause it to overheat like mine (only took 2 seconds). I can safely advise going on ebay and picking up a more powerful unit for cheap or geting a secondary unit to reach 800 watts. You won't safely be able to go to 800 watts.
Just picked up 2 of these APC UPS's that somebody just threw in the trash, batteries and all. The battery was discharged, unfortunately, but seems to have charged back up after plugging in (getting about 13-14 VDC on the meter).
Just using them for surge protection, which should be better than the old Radio Shack power strip w/spike protector that I was using.
So what kind of run times do you get out of it? I have the same UPS and the battery has failed, and I'd like to replace it with a deep cycle battery like you've done here.
@winterlike I get about 3-4 hours max if I am editing or gaming, 5-6 with browsing only. It didn't work out so well with this specific ups (the 2 amp 200 volt diode blew up in smoke). It didn't blow because of the battery, its because my pc has a 300 watt psu vs the apc es 350's 200 watt max. I replaced the diode and the entire ups with a 450 watt tripp lite ups. You can still use your es 350, but make sure its using less than 200 watts or boom!
The apc trickle charges the battery @ 1-2 amps, so a partially discharged battery should take only 24 hours. If there is an emergency and I have to use up to 50% of the battery, I use a smart 6 amp battery charger for it. The funny thing is that I am sending this ups back for a bad diode that was recalled years ago. I am just going to replace it with a bigger ups and hook this battery up to it.
