CyberPower UPS Battery+Surge Outlets Suddenly Not Working?

The thing is i know this UPS needs battery replacement and it seems I have to buy 2 batteries correct for this? I read reviews people said you need 2 batteries for it. This is the correct battery for it but i need 2 right?

This seems ridiculous because buying 2 of these cost like 60-80% of buying a completely new same UPS.







However, if you buy it off the US website, it's less than half the price here.

But would this below work as well? Seems to be the same specs as above but half the price?

The thing is I have no clue about opening a UPS. I am concerned I will make a mistake and break something. But is this an easy process to replace the battery? The other thing is, would there be any dangers if you do it wrong like you would cause the battery to release a chemical smell and it's dangerous if you don't do the procedure correct? There is 1 or 2 computer shops where I'm located that most likely can replace the battery without an issue. Should I first bring the UPS there just for them to examine that my UPS still works even though there is that red light Wiring Fault and this is just a battery issue? If so, how much money should one pay for them to replace the UPS battery for you if you provide them with the batteries if you buy it yourself?





Does it make sense to just buy a new UPS then based on this? If replacing the UPS batteries which requires buying 2 batteries cost half the price of a new UPS, then it's worth it but once it gets to around 60-80% of a new UPS, it might be better buying a new UPS? The issue is UPS is very expensive if I buy it where I'm located though and electronics in general.

Yes the cyberpower 1500 VA UPS looks like it requires 2 batteries. Replacing the batteries appears to be relatively simple and there are You Tube videos on this. When replacing my UPS batteries I prefer to go to a local vendor. There are various battery vendors in my city. If there are none where you live, then you may be out of luck because many on line vendors are not able to ship these batteries via US mail.

Are there any safety precautions if you do it wrong though and don't have a clue what you are doing? Like there are youtube videos but if there is mistake, could it cause a boom or acid coming out? There is a local computer shop here that most likely can do this but how much do you usually pay? Or you mean you go to your local vendor to buy the batteries but you replace them at home?


I could buy it in the US first but could also buy it over there but it's 2x the price at least. However, not sure if there is an issue with the UPS itself so wondering if I should go to local computer shop first before ordering 2 batteries. Issue is battery+surge outlets all don't work. The surge outlets do work. There is that bright red light on wiring fault but not sure if that is related to my battery or not.

Whenever my UPS units need a battery replacement, I buy them at our local vendor, Battery Bills.
I am not sure what the red light means. I am assuming the red light is a new thing. As mentioned before, my UPS had the following problem: surge only outlets worked, surge plus battery back up outlets didn't work. Pushing the "on" button wouldn't turn the UPS on. I had to reset the battery by 1) unplugging it from the wall outlet, 2) unplugging all devices from the UPS, 3) disconnect the battery from the UPS.
Then hook everything back up and turn UPS on. After I did that, the UPS functioned normally.
