- This is my UPS I have for my gaming PC, modem, router, and TV in case of brownouts or power loss. I have hooked up four 12v Eaton Powerware 12280 VRLA AGM batteries with two 24v series connections. It is an online server grade UPS and I replaced the aged batteries with my own batteries, so I didn't have to buy the replacement 18 Ah RBC55 batteries for around $250-300. I am in the process of setting up Powerchute Business Edition to monitor the battery voltage and the data logging of I'd I have any significant power loss. Typical automatic transfer time to the batteries is about 2ms so it allows me to comfortably run my systems without fear of improper shutdown or damage to any of the electronics.

Nice setup! I have a cyberpower 1500va 24 volt. Was thinking of trying 2 12 volt 100 amp hr agms. Have you let them run out completely and let it recharge completely on its own? If so did you have any temperature issues? Also how many times did you test like that? Just concerned when not at home if I have an outage..
Although its a 48V system , your battery cables looks a bit thin for a 2200va load ( about 1800 watt) . Do a test run on full load and see if any of the cables get warm. I got mine from work too. Had a tough time lifting this up and load it in my car. Enjoy! this is a solid unit.
Yeah it is 10 gauge all the way back, but I never really ran a full load on it. It's been unhooked for a while, I got a newer SMT1500 UPS and use that in it's place. I have my backup batteries hooked to my Genny panel so the UPS takes the initial hits until I manually switch to backup batteries or generator.
since it's a 48v battery, the current would be relatively less. They look ok for 30A load.
I can't believe how heavy these are
how much energy it uses when idle/stend by ?
because I'm thinking about buying this model or a weaker version sua1500
Hello, thanks for sharing your knowledge. I wanted to know how long the UPS lasts with those batteries. It's worth it? How long does it take to fully charge the batteries? Is UPS effective? I wait your answer.
Good video...... have you made a video showing the full build & set up.. that would be interesting.
No I actually never made a video of that, but it was basically no modifications. I only made the Anderson connector wires longer so I could house the batteries outside of the UPS. I could've made new ones with some 8 gauge instead of the existing 10 gauge, but I wasn't running anything crazy so I wasn't worried about it. Other than that just a stock UPS.
Got two of the 2200 VA rackmounts but the batteries died in a matter of months. They were brand new PowerSonic batteries, so I'm not sure of it's an issue with the UPS themselves, or some kind of setting I screwed up. Feels bad.
Are there any major concerns when it comes to this system or manufacturer? I'm planning on using the SUA3000XL for my server racks as a backup and I need to make sure I replace or fix any common issues beforehand. Any feedback would be greatly appreciated. Thank you!
I've had good experience with APC/Schneider electric UPS systems. We use them everywhere at work also. Just make sure it is clean and free of dust and dirt, check the fan if it has one make sure it's clean and working etc. Check the batteries/voltage and the connections with the Anderson connectors, and wires. Basically just make sure nothing sticks out as abnormal. Hope this helps a little!
hi sam so based on your accent you are somewhere in the US (finally, most video's showing the apc2200 are from the uk) as i am too, and a friend gave me this unit with bad battery's, and cabling, no stickers no model number on it, and i had to open it up and take the model number from the internal board, so at first i was sure this uses 220v but as i found your video and i am in the US to, i am not so sure anymore i thought it might be a good idea to ask this stupid question, does it take 220v? or 110v?
Mine takes 120v, but there are 240v versions here in the US as well, I have seen them at work. They would be hardwired typically but if it was a 220v(240v here) it would have 2 hot legs on the cord or terminal strip. The 240v units are all high powered too, 3000VA and up, mostly rack mount style. hope this helps, sorry for the grossly late response!
Hello! This UPS was recommended to me by a technician for my use case. There is barely any information on this one and it. How loud is this UPS just with the default batteries? Do the fans turn on all the time?
If it is the same one as in the video, it's kind of loud and noticeable just because the fan is on all the time. It ramps up and down based on load when on batteries. It is designed to be a server-room type UPS so noise isn't usually something that matters for it.
@@SamsDIY Thanks a lot. You've saved me money!
I am still a bit fuzzy on your hookups here. It looks like you have _2_ sets of cables from the big 12V the batteries to the UPS. Are they wired as a pair of 24V (2 x 12V series-wired) packs going to separate Anderson connectors inside the UPS?
I ask, because I have 2 units: a Smart-UPS 2200 and a Smart-UPS 3000.
They each have a set of 2 x 24V packs (series-wired 12V batteries) connected to separate Anderson connectors). Would a series-wired string of larger 12V batteries need to be likewise split into 2 x 24V packs, each connected to a separate Anderson plug?
Finally, the Smart-UPS 3000 has a connector on the back for a 48V extended-runtime battery pack. As it is a single connector, I assume that a single series-wired string that adds up to 48V is all that is required, correct?
(For other readers, the 2 units have very different stock battery setups: the 2200 has 2 packs of (4 each) series-wired 12V, 7Ah batteries. The 3000 has 2 packs of (2 each) series-wired 12V, 18Ah batteries.) Thanks for any insights.
I set them up as they are normally wired in this unit. This one has 2 sets of 2-12v 7ah batteries wired in series at 24v. So 2 pairs of wires from each set of 2 batteries going into the 2 Anderson connectors inside the battery housing. I believe it is a 48v unit. I did no actual modifications to the unit, just grabbed some longer 10ga. Wires and threw some Anderson connectors on and called it a day. I have since gotten a couple newer units and just use those instead. I have large backup batteries for the house that takeover after the ups takes the initial hit. Hope this answers your question!
Just wondering if the unit could handle charging such a battery array from low voltage. Would it supply enough current ? Would be interesting to check the specs to see if you would cook the UPS charging from flat / low voltage. Great idea though... Cheers :)
You could disconnect the unit charger and put one in its place maybe, I'm not quite sure if it could accept the lower voltage but I'm sure you can figure that out relatively easily. I forget if it charges at 24v or 48v, because it is two 24v banks with two separate Anderson connections inside the unit. But I know the unit itself runs on 48v.
I have exactly the same unit. It runs on 48v dc so all 4 12v batteries are wired in series in the standard configuration.
I've got mine hooked up to 4x 80ah deep cycle batteries for now.
Charging is a little slow as the charging circuit on the UPS is rated at 271watts.
It puts about 4amps into the batteries.
The standard batteries were 4x 12v 18ah in series to give 48v 18ah
Hi can yu set the charge voltages etc? i was wondering about doing this exact mod, but my cells are Tubular plate GEL not AGM and have slightly different voltage requirements Bulk & absorbtion of 14.4-14.7 per battery Float of 13.8 per battery with a Temp coefficient of -30mv / C
Not on this UPS you cannot change the charger parameters from the factory that I know of. You could always just remove that charger and hook another with the parameters you require in it's place.
@@SamsDIY it is possible to change the charge voltage, but that wont effect the current in the desired way, but would reduce total charging power
How you charge those huge battery ?
Hi, I have the similar APC but I tried to use UPS12-300MR C&D Dynasty battery but seems is not working, Do you have any idea? Thanks
Is there a battery disconnect on the back? The APC units have a battery disconnect on the back for shipping purposes. I'm not familiar with those units but I will see if I can find anything! Good luck!
How to set battery calibration for true runtime with large batteries?
I believe you can do it through the PowerChute program, you can download it for free online. Then you would need the communication cable from the UPS to the computer and you can run a new calibration there with the bigger batteries hooked up. I remember seeing it on there. Hope this helps!
I have same ups , please show me how to do that , i mean how to connect those orange cables inside the ups
I just made up some longer 10ga. wires to reach from the Anderson connections inside the battery compartment to the external batteries. That was all, it worked well, very simple.
Hi Sam,
Could you please provide us more information how calibrate ups with larger batteries such x4 100Ah, please?
In your case scenarion the batteris are 75Ah model, total= 300Ah.
How to adapt UPS 12v 100ah batteries?
To get the best battery life and runtime you can the UPS has to be reprogrammed?
Could you please helping with this, or posting on Reddit,
Cheers.
You should be able to run a calibration through the unit itself or the Power chute software on a PC. It will run the batteries down completely, lower than 50% as it normally does so keep that in mind. I'm not sure if you can set the voltage to 47.2v as 0v. I'm not sure what the cutoff is from the factory. Wish I could be of more help!
The 4x 12v batteries are wired in series
So 4x 12v 100ah batteries gives you 48v 100ah.
With series the voltage increases but amp hour does not.
In parallel the voltage stays the same but amp go up.
@@SamsDIY 10.5v is considered flat on these units as default so 42v dc on the battery pack
Generally they will shut off at about 11v so 44volts
@@mushymarlin Yes I should've explained that they are wired in series to 48 volts. Thank you for the clarification! Also thank you for the specs!
@@mushymarlin my 3KVA UPS starts flashing red when the battery voltage shows 67.5v (6x 12v 9ah batteries), so that equals to 11.25v per battery at low cut off. I havent tried pushing it further than this
so the UPS knows how to properly charge the aftermarket batteries? I assume you need to use the same type of battery that the UPS is designed for (lead acid as opposed to lithium), the only difference is the amp hours
Yes exactly, I used some VRLA (valve regulated lead acid) sealed batteries which are the same type of sealed lead acid batteries that came out. Most UPSs I've seen are VRLA batteries and I have not seen any with lithium as they require a different charge profile. It probably is a little more wear on the charger since it would be charging for much longer.
Hello can you please give idea how can I do this project for my village in Africa
Sure, if you have any UPS of a decent watt/VA rating with a built in fan, you just needs to make up an Anderson connection from inside the battery housing compartment and run it however you like out to a set of larger batteries. In this case the UPS is 48v so I had to use 4 12v batteries wired in series to make 48v. Nothing was changed internally on the UPS besides utilizing the old APC Anderson connectors. This unit is a 2200VA-1980watt model for server rooms etc. So it has plenty of potential. Just keep in mind the charge time will be a bit longer since the batteries are much larger. Just keep an eye on temps, I used Powerchute software to monitor this. Hope this helps!
Make sure you use AGM/SLA batteries and not car batteries. Car batteries are not designed to be discharged often. UPS batteries are designed to be discharged and recharged fully. But it always is a good habit to minimize the time the batteries are discharged.
@@Aranimda agreed!
@@Aranimda what about agm car batteries? like in stop/start cars?
@@redwrym AGM car batteries are fine. Actually ordinary (water) car batteries will work well but they are just not the best but if that is all you have they can do. Make sure to check the water level in all the cells. If possible have to the connection cord long enough to keep batteries next to a window or even outside if the cord is long enough.
Sorry Mr I beed your contact
Tengo uno de esos en cuanto dinero lo puedo vender???
