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.
Regards,
Technical Support

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."
> "Had one of these start a fire back in 2015 at my clients office. Burned the entire rack and caused 500k worth of damage to the building. They sent fire investigators from the insurance company and determined it was a faulty UPS."
