CyberPower UPS Battery+Surge Outlets Suddenly Not Working?


I have mostly cyberpower ups's. It always seems a hassle to replace batteries. Unplug all devices, I used to take the ups to the garage work bench, perhaps your wife will allow you to do it on the kitchen table :O and remove the battery access cover, slide the batteries out, disconnect and reverse. So what I did was, [my example below requiring 2 batteries at a time] was just extend the wiring from inside about 2 feet of heavy gauge wire, put on connectors and built a container and connected the 2 batteries in series. This way is much easier to change, measure the voltage on them, keep clients plugged in etc. I used the same 12 v battery but bought some with higher amp hour rating. Some ups's only require 1 battery. Only do this if you are comfortable with this kind of work. YMMV
So you recommend against doing it myself then right? My concern is if you do something wrong, there could be a boom or like someone else said like acid coming out where it isn't safe? Would it be dangerous to do this if you have no experience at this stuff? Other people seem to say it's easy and simple but you say it's a hassle but is it unsafe if you do it wrong?

I have been using the UPS as a surge protector the entire time. But now I want to replace the batteries. I want to know if there are any safety issues if you don't know how to do it correctly.

I've changed some and found the only real issue is the stiffness of the wires connected to the batteries, took some strength to disconnect. Also, over time I've considered the cost-effectiveness of changing batteries in older units that may file at any time versus just getting a new one. I also consider the shipping weight of batteries versus a complete unit. Local availability is also an issue.

With the questions you have been asking I feel you would be better off buying a new UPS. If you were to take it to a shop between the price of the batteries and then the labor cost it may wind up costing you more.

The OP has a history on here and other forums of doing exactly that... rarely directly replies to any advice, keeps asking the same questions and never offers any thanks.

I keep telling myself to not reply to his post but it's hard for me not to want to help someone.

So I'm still using this Cyberpower UPS as a surge protector basically as I never went and bought 2 new batteries for it. I have noticed that a few times, the UPS would power off? Is this normal? This probably happens a few times a month and when it does, my 2 external monitors turn off and my laptop is on laptop battery mode. But when I click on the power button, it then powers it back on. Now if it happens overnight, I would know this in the morning when I notice my 2 external monitors are powered off and my laptop screen as well. My laptop screen would have a low battery. But when I power on the UPS, then things are back to normal.


This is what happens if you use an old Cyberpower with a bad battery right? But there is no issue continuing to use it as it is like a surge protector?



Would it make sense to buy 2 new batteries for it and then bring it to a computer repair shop for them to do the installation or that isn't worth it? Is it better to just buy a new UPS instead? The thing is I don't want to install it myself as I read if you install it wrong, it can cause a ton of issues?

I had this UPS for about 6 years maybe and basically never used it until I had to during a power outage. Back then, I plugged everything to a surge protector. The UPS rarely was powered on unless a power outage and then I connected my laptop to it etc. I didn't find out later on that was the wrong thing to do and you suppose to connect everything to it. I had thought... if no power outage, no point of having a UPS turned on at all. Only turn it on when a power outage and connect laptop to it. I had treated the UPS like a power bank where I keep it on the side until I need it. And I rarely used it that much as well.



So I made sure the UPS battery was close to 100% before I shut it off so when power outage, then it would have a lot of battery. I sort of knew that the battery would wear out if not having it turned on but I didn't know batteries last a short time even if you rarely used it. That is true right? It wouldn't make sense to buy 2 new batteries for it and pay a computer shop to install it right compared to buying a new UPS?



Does anyone know how long a UPS would keep a laptop on or possibly a laptop and one 4k monitor? I know it depends on how much watts your devices draws. Back then, I recalled I tested my old XPS 15 9550 which had an i5-6300hq processor. I believe if I connected my laptop which is at 100% to it and my UPS battery is 100%... I think I might have gotten 1.5 hours to maybe 2 hours at the most. Is that about accurate or sounds like too much? If I used a 32' 4k monitor with it, it probably last a total of 1 hour at the absolute max? I wasn't aware later on a UPS isn't meant for that... it's meant to give you enough time for your devices to turn off safely. People said you want a generator for that.


My XPS 15 9520 uses a lot more power right since it's i7-12700h? What I did notice about this i7-12700h compared to my old XPS 15 9550 is I compared using a similar power bank with each of them. My old XPS 15 9550 I used a Dell 18000 mah power bank and I recalled I got around 1 hour 45 minutes to a bit more than 2 hours on it before the power bank went off. Is that normal? When I used a Dell 18000 mah usb-c power bank with the XPS 15 9520 laptop, it got at most 50 minutes before it went out. I was shocked by this. So with the UPS if I get the same one again or new batteries for it, don't expect much more than 1 hour on it then? My Anker 737 seem to give my XPS 15 9520 about 1 hour 5 minutes worth of backup before it goes to 0.
