What is maintenance like on an UPS? Isn't the battery constantly being overcharged? How often should you replace a battery in an UPS?

Different UPS systems have different maintenance cycles. Just had to replace the battery in a smaller, consumer level UPS after about 3 years of service, it is now back in use and working fine. At work we used a 2 year maintenance cycle. A UPS would be rather useless if it didn't have circuitry to monitor both power quality in and battery working state. This CyberPower unit has been nothing less than awesome so far.

I've had my since February 2013 and haven't had to do anything to it. I don't think the battery is being overcharged- I think it turns that function off once it has full capacity. There is one side with half the plugs that is battery and surge protected and the other side with the other half of the plugs with surge protection. I am very happy with this item- it's plugged in under my desk and I've never had to touch it.

I bought this in April 2010. I had a power failure and the battery lasted 5 minutes with just two small things (Cable modem, WiFi router) plugged in. Hence, the battery doesn't last 3.75 years before needing replacement. Or, maybe the whole unit is dead.CyberPower RB1280X2A 12V 8AH UPS Replacement Battery Cartridge for $73 or an new unit for $130-ish. Disappointing.

Yes, had the same issue. The problem isn't with the UPS systems but the devices power sync modes. When the computer goes into a low power state, such as kicking from normal power to UPS, it kicks the device into power saver mode and shuts down. I fixed my issue over a year ago and unfortunately don't remember exactly what is was that resolved it, but it was from this forum thread. Good Luck http://forum.mediasonic.ca/viewforum.php?f=22

I have had mine close to a year a year and haven't noticed any major issues. I will use mine for an hour to offload and then turn off. No shortage of battery had been noticed. If I had approached and exceeded the year mark, I supposed I would break the seal and seek out a a replacement charging device. My use is to basically offload 64GB or so of photo data and the to repeat the task again, at which time I would put the next 64GB on the Nexto to await being offloaded with the first batch to my PCs external drive at home. It's not excessive use, but it is busy work across several hours in an evening. I have had mine close to a year a year and haven't noticed any major issues.

The best way to find out how long it will last is to go http://www.apc.com/tools/ups_selector/US/en/server/load . You can input variables such as load and time and see what models are most appealing either on a run time or price basis.

I love my Roombas.......buying used roombas from Amazon is a great buy, but the one I bought was extremely dirty. The second one was perfectly cleaned. (I have three; two in a two-story vacation home and one here.) I clean them often (easy) and run them frequently. I have only had to buy a new battery once. They like to be kept clean and run fairly often. Here at home I run Roomba in one room, then the next day another room and so on. It was worth the extra charging station that I bought, but it's not necessary. Definitely, it's worth a try for you.

In my experience with UPSs, mine would only buzz while switching to battery power or while charging. I would contact the manufacturer and request a repair or replacement.

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.

Has anyone had issues with battery maintaining a charge? Mine will charge and then drain over a few weeks and. I'll then find that it's disconnected from the network due to a low battery. I've had mine installed for a couple months and it's done this two or three times.

It depends on the load on UPS. If you are utilizing only 10% of UPS capacity, it should last much longer.

I run 2 Servers in my home office (I am an IT Consultant), plus the rest of my home on this unit. About 5 months ago we lost power for 48 hours and we ran the generator using Natural Gas. I had a couple of hiccups with some of my UPS's due to voltage fluctuation. I think it has to do with the sensitivity of the units. My older UPS units did not have an issue. I have found out from others in my field that this is common with newer units. I have APC older units and they did beep every once in awhile, but the equipment stayed on all 48 hours. The newer units did not and once the battery was used up, the equipment turned off. I don't want to give out model #'s because just because mine worked, I can't guarantee it will work for you. Once it gets warmer around here I am going to try and put surge suppressors in front of the newer units to see if that helps. If not I would try to put cheap UPS's in front of the High Capacity units. Hope that helps. BTW, I have my generator connected using a manual transfer switch and when I lost power, I was able to be on generator power in under 3 minutes.... Power went out... I went outside, removed the cover, turned on the Natural Gas, turned the key... That was it. I use a battery tender always connected to the unit so the battery is always fully charged. Total install including the generator was under $2600.

I agree with Derrick Davis, it all depends on how much you are running on it. The UPS is only designed to run long enough for a proper shutdown of the computer in case of a power outage. A minute to save your work, a minute to shut down should be all you need.

I have actually tested this but not with UPS's that have Pure sine wave. When I tested this with cheaper ups's it resulted in damage to the second inline ups. Also both batteries drain at the same rate so does not give you double the time left. There are ups's that are actually made to be run in series but those are expensive as we use them in our office at work. Those are made different then these.

The shelf life (time it can sit without being charged) is 6 months. If the battery will not be installed in an alarm system or UPS battery back-up (or any other device that trickle charges), then it should be top charged every 6 months to avoid permanent damage to the batteries. If it is installed in a security system or battery backup, these devices automatically keep the battery charged so it does not need to be maintained. The batteries we ship are fresh date codes and fresh from the manufacturer. Best Regards,Battery Supersite

Uninterrupted Power Supply. Yes, you should be ok to use this with a UPS. It really comes down to what your plugging into the whole system that will dictate how the UPS acts.

Hi Matthew. I see where you are going with this. I don't see an actual date on the battery itself. This info may be part of a serial number or another code. I am finding that the replacement battery is not holding a full charge the way I think it should. My opinion is that replacing the battery is simply a temporary solution. Every once in a while I get a message that the battery has less than 5-minutes backup left. This is not right! When I am faced with having to replace it again, I would very likely buy the whole assembly new. Hope this helps.

I wouldn't be too concerned over battery life , haven't had any issue with mine and it gets used frequently . anyway if I remember correctly installing a battery was a breeze .

Per the manual that comes with the unit, it says "Your UPS requires two Tripp Lite RBC51 replacement battery cartridges." For more information visit Tripp Lite on the web at www.tripplite.com/support/battery/index.cfm.
