Guy in the imgur said that happened after overload error and this happened after he replaced battery, giving just the benefit of the doubt that overload might have damaged the unit already. Also if anyone planning to open, I would reach out supplier rather than breaking any possible warranty. But also home safety no joke, so there is that. I got 2 x 1300, I really liked , its been half year, only the having possibility of battery leak scared the .hit out of me because new units has new iron burn smell. It goes away after few weeks.
I too have one, but it is the 230v/50hz Australian/NZ version CP1500EPFCLCDa, I'm thinking I might have to whip the covers off this week and check for glue.
my 1x VP1200ELCD and 2x VP1600ELCD are australian models as well. Its not something I have a lot of time for atm but maybe next weekend I'll crack them open to see.
Same model here. I don't think it's worth opening for me as mine are brand new (less than 3 months old). At best I will see yellow glue which doesn't mean much. It's the presence of brown glue that indicates it's the low quality problematic stuff.
Turn your setup into an in-line UPS. Have your equipment always running off of batteries, but keep them always charging. When your mains power dies the batteries will continue to discharge. There is no 'switch-over' time as the computer is always running off batteries.
the line-interactive (cheaper than on-line) in my experience play well enough with servers as long as they have pure sin wave/stated that they are pfc compatible.
In my experience they allow through transients from the supply that will often reboot servers. It likely depends on your particular supply scenario. In our case we have 10 miles of 7.5KV transmission line between us and the substation.
I had one pop on me during a power outage a few months ago. I was quite miffed. The only halfway decent looking UPSes have annoyingly loud fans on them. Still, the fans probably prevent the thermal issues.
When you say pop, what does that entail? Did it spark up and start a fire. Did it just smoke? I think that's an important distinction. Did it just stop working (as if lightning had ran in on it like you'd get on an unprotected device?) I don't care if the device fails at some point, I am much much more worried about it starting a fire.
This is a problem of supply chain quality control. Someone decides to save $1 a liter on potting compound and buys cheapest bathroom grade acetoxy stuff, or worse uses random glue from cheapest supplier available.
I woke up one night to that horrible burning motherboard smell. Ran into the office and noticed it was the UPS. Somewhat freaked out (would have never expected that to go on me in this manner). I unplugged it ran downstairs and put it in the middle of the driveway. After watching it for about 10 minutes I went back to bed. Disposed of it two days later (after taking the battery out to eliminate a runaway effect.
Yeah. If you’ve ever smelled burning electronics, you know that smell. In some ways, that’s a good thing as I knew where to go first. Of course, being the ups instead of the computer was weird to experience at 3 am. Hard to get your head to think through that when you aren’t fully awake, but starting to panic.
Yeah, I came across this when I was researching UPS models since I have a few I need to replace with sine wave units. Unfortunately the current generation of APC's consumer PFC UPSes also have a reputation for catching fire.
At least this is a cause I can pre-emptively fix ony own, I guess.
I was just looking up UPS models, I have the CP1500AVR, is that effected? It looks like all the complaints are on the PFC. I was getting wary when I saw some Amazon reviews mentioning fires including the EC850LCD. I've also read fire stories from APC. The Amazon site has the APC Gaming UPS even having countless reviews about it popping, smoking, or catching fire. So, I don't know which company to trust.
I have also wondered how many reviews people are getting counterfiets. It's hard to tell anymore.
I've been looking around since reading this, the problem with the Eaton at the similar price point is that it doesn't have the features or outlets that APC and CyberPower have. The APC UPS 1500VA seems to have good reviews all around and is similar to our model. Eaton's Tripp-Lite units seem to have some similar.
Mine is getting up there, I think I will unplug it and just use a standard surge protector until I can get an adequate replacement. During my last outage I noticed it was struggling to hold the load and only lasted 10 minutes, where it used to last 30. So it needs replacement anyhow.
I have a CP1500AVR from 2013. I think it's had two battery replacements. Still going. I don't trust it to deal with aging batteries well. Just like my CP1000PFCLCD it tends to get very hot with aged batteries. My solution has been having them placed under my desk in a way that I can feel them with a bare foot. Excessive temps let me know it's time to replace. Usually 4-6 years in practice.
I was replacing hard drives every few months until I used a UPS. Once I replaced all the drives I’ve been good ever since. UPS is essential for a NAS.
Been using this model since 2019. Just replaced the batteries for the first time this week after the UPS threw code E02 and had a very hot battery compartment. The cells were bad and there was no battery backup possible anymore. Things cooled down a lot after the battery was replaced and the battery backup works again. I’m happy with it.
It connects over USB to the Synology to tell the server to shut down on low battery.
I also have a VP1600 (in the UK), very much in the same position. Not a fan of delving into stuff that deals with power, hoping this isn't a general problem. I'd be interested in an update if you do take a look.
For what it's worth, the CP1350PFCLCD I had died a strange, non-charging death where it would take about two weeks for the battery to discharge and start screaming (while being plugged in). Serves me right for cheating on APC.
Most people assume surges are bad and use surge protectors. However, undervolts/dips/brownouts are just as much if not more damaging and people unawares don't realize that a surge only protector does nothing for them. At my house, the dips are much much more frequent and is why I have a UPS for my TV and other entertainment gear.
Please consider — not to preach :) — please consider recycling it rather than just dumping it. Shit from that battery will leech into the water supply for years. Most municipalities have some way to recycle batteries. Cyberpower has a page about it, too — https://www.cyberpowerpc.com/company/recycling.aspx
Oh yeah, by “take to the dump” I mean pay for a disposal sticker and put it in the e-waste shipping container with the other things to be recycled (which I am reasonably sure my town actually recycles).
I’ve had so many of these because it’s the model CostCo sells. They often fail randomly, but otherwise have been okay. I wonder if this is why they fail so often.
I have one of these. I have had it for years, and even swapped out the battery pack once. I have had no other issues with it.
After I read the Reddit post and watched the tear-down video, I disconnected and opened it up and found that not only did it have the yellow glue, but patches of it had turned brown and had what looked like drops on it in places.
Now I am looking for a replacement, but from the comments here it sounds like other manufacturers have the same issue.
Also have one. Also replaced the battery. The other thing I don't like about it is that the battery is lead-acid, which is extremely toxic and extremely heavy. But when I looked into that, I could not find any manufacturer that offered a consumer grade lithium-ion product.
I'm giving some thought to brewing up my own UPS. Mostly for capacity, which is tough to get in a residential unit at any price, and quickly becomes expensive if you try. Technologically, it is not particularly difficult. You buy a halfway decent inverter/charger from a reputable manufacturer, and however much LiFePO4 capacity you want. I would not choose lithium ion; LFPs are considerably less likely to combust.
How do you achieve the X <= 10 ms switching capacity? You need this if you actually want your equipment to survive the power outage.
Also, I'm extremely sensitive to humm noise output by inverters so I can only tolerate UPSs that have that "Green mode" option which (I guess?) powers directly from AC when under quality power but still provides protection.
My preferred inverter/charger manufacturer, Victron, has "UPS Mode" for their Multiplus units that will switch in 12ms. That's similar to many UPS's, though some of the higher end ones are sub-10.
A few years ago ESR started on an open source/hardware UPS project called Upside.[0][1] I can't vouch for the design as I haven't looked at it in a long time.
Food for thought: lead-acid batteries are the most recycled things on earth, at around 99%. Probably because they tend to be large, so they have a high volume to surface ratio, and are relatively simple and easy to recycle compared to more modern battery types, and many automotive related companies are required to have recycling programs for them, and they've been around for many decades ...
Fair enough. But if it is in an electrical device with shoddy glue that is likely to catch fire or explode, then it would be nice to not be given a lethal dose of lead in addition to my place burning down.
Personally,.I would much prefer my odds as an adult in a lead poisoning/fire situation than a similar li-po situation. Going with the more complex battery is basically choosing a future of experimental medicine over treatments with long and successful track records.
Laptops typically get replaced every 3-4 years, and a major requirement for them is to be lightweight. Lead acid batteries are far more economical for applications where weight is not a concern.
It's not the lithium part of lithium batteries you worry about, it's everything else. Lithium hexafluorophosphate turning into hydrogen fluoride gas, for example.
I still have my lead acid batter in my UPS from... 2016? I'm not even sure when I got it.
With lithium I need to know when I got it, did it run in non-ideal lithium conditions (-20^C? No go. +34^C? No go), and the most importantly - in three years I need to replace a Li battery, but with a lead battery and a non-online UPS I can have from 3 to 10 years of lifetime from it.
Solar "all-in-one" inverters are a good alternative to a UPS and fairly inexpensive. (~$400 for 1kw). Solar panels aren't required, just bring your own battery (lead acid or LiFePo)- you could even pull the batteries from your existing UPS.
I just got what I think is very poor response from CyberPower who tried to discredit the people posting the videos:
"Thank you for contacting CyberPower Technical Support.
We are aware of the video and we totally understand and appreciate that you brought it to our attention to confirm this.
The person who posted the video offered no evidences to support his claims in the video as he only used assumptions.
There were no presentation of test results or industry data provided to prove his claim. CyberPower products are UL listed for safety and the rubber glue we use is also UL listed. Finally, CyberPower has thoroughly tested the rubber glue we use, and our results are aligned with industry information meaning there is no danger of the UPS catching any unfortunate events or shorting out as a result of the glue. The results debunk the claims being made in the video.
I hope I have shed a light about this concern. Rest assured that all our products are safe.

The person who has the video on YouTube discussing the poor design is an electrical engineer, he has no motive to discredit CyberPower and appeared to provide the video to help people avoid the problem.
I must say that your statement "all your products are safe" seems a somewhat hand-wavy response to what appears to be a potentially deadly design flaw that many people online have independently reported to have experienced, several with video footage.
Check the response on reddit, YouTube, ycombinator, and the engineering forum linked, accounts I have inspected and seem to be credible / legitimate people have said as such:
> "I had a CP1000PFCLCD model that did the same thing. It threw an overload error and the company said to replace the battery. Once I put the new battery in it started making odd noises and began to spew smoke. Thankfully I was home and caught it quickly. The unit was four years old."

This is a problem with almost all modern UPS's. I had some of the old APC's that had the aluminum case with the high quality circuit boards with adjustment pots. These units were purchased in the mid to late 90's and were rock solid, I finally retired the last one about two years ago because it ran out of adjustment on the pots.
I've have numerous later model UPS's made by APC that have gone up in smoke when they were needed most or just up and die for no good reason. The units I have now are supposed to let me know when the batteries need to be changed, but that feature is a total failure.
The first place I ever saw a CyberPower was years ago on an Amazon sale. I was not familiar with that brand and much more aware of Tripplite and APC gear. I assumed it was some sort of cheap knock off available from Amazon only.
I have no idea about this company, but they were definiately part of the collateral damage of me being highly suspect of any thing on Amazon that is from a brand name I am not personally familiar. I don't know if that says more about me, Amazon, or CyberPower.
Could this kind of issue be avoided, at home, by simply setting the connected device to shutdown on power interruption?
I have a UPS connected to a NAS and because it is non critical I shutdown after 1 minute of lost power, and I think it can turn back on automatically when power is restored. I only care about data integrity, not uptime.
I had to place my unit (CP1300EPFCLCD) in an empty room for 2 weeks to let it out-gass, the smell of plastic was unbarable and was not suitable for living conditions. I found others complain on the web just as well.
After two weeks I measured the amount of VOC in the room for a couple of hours and there was still some presence but nothing to worry about.
A different less catastrophic problem with at least the CP1500PFCLCD is that if it detects a battery or charger fault, instead of continuing to run in bypass mode, it is designed to immediately cut all power to the load until it is power cycled. As far as I know, this behaviour is not documented anywhere, so you only get to find out when it is too late.
no it doesn't. It just shows the location where you can find the glue. How do you actually remove it? Do you soke it in ethanol and pick it apart or how ?
I think UL cert is pretty much pay to play these days, could be wrong but you know - you pay for a cert for something then you can put the logo just about anywhere.
I just took apart my unit CP1300EPFCLCD and it indeed has the yellow silicone. There's also a lot of white silicone but only to keep wires in place.
My solution is to just inspect the unit every once a year to see if any yellow glue is turning brown just like in the video. Meh ...
Edit: A closer look showed that some parts of the glue already turned brown. It seems to be affected by heat because the parts that are brown are the parts making direct contact with the board/components.

I have contacted CyberPower for more information.
any idea how he cleans them off?
step 1: exploratory surgery of UPS
step 2: finally install new smoke detectors
The real bummer it's that I got 20kw of batteries a few months ago but they don't kick in quick enough compared to ups, so need keep on using ups
A forum member on that RedFlagDeals.com post says that they've seen the same epoxy compound on various electronic items from 1970s, 80s, 90s.

Be sure to install extra smoke detector around your PC area.

I also have one of these on My PC and a VP1200ELCD on my wife's setup... I'm seriously considering cracking them open to have a look :-/
Guess it’s a good thing I switched to Tripplite.

Could make a post-PSU UPS, then you don't need an inverter at all (also the most efficient design, no conversion losses)

Lithium is toxic too and never gets recycled.
> and extremely heavy
Yea, it's like you move your UPS every day?
With lithium I need to know when I got it, did it run in non-ideal lithium conditions (-20^C? No go. +34^C? No go), and the most importantly - in three years I need to replace a Li battery, but with a lead battery and a non-online UPS I can have from 3 to 10 years of lifetime from it.
Look in boat stores for battery charge level protection breakers.

He does have one potential motive. Profit. From views.
I am not saying this is why he posted the video, merely that this motive does exist.
But posting it here on HN might get it read by somebody higher up.
