UPS constantly turning on/off every 2 seconds

[JEDI]

cyberpower 625va

it's 3years old.
all of a sudden, it just turns off/on.
I have nothing plugged into it now and it still does it.

here's the user manual (I think): https://system.na2.netsuite.com/cor...120&c=4820964&h=63c38b12bba532b659a3&_xt=.pdf

manual is of no help.

what's wrong?
just buy a new UPS?

The batteries in it are likely bad.

You can buy some new batteries and replace them yourself, or buy a new unit. You can see the price of the replacement batteries on places like Amazon or Interstate Batteries (and many other sites, but those are the two off the top of my head).

Agree with UsandThem. Replace the battery.

I'd just buy a new one personally. You can get a new CyberPower 650VA for $49:

holy.. where did all these supermods come from?
was my post near a telephone booth?

and a 650va ups is overkill for what I need it for, which is just to keep my small internet router alive so I have wifi incase of a power outage.
the 650va I was using was because I had lying around.

Much like "Big Brother" in the book 1984, we're always watching and waiting.

Unless the UPS is an enterprise class product priced above $1K and the replacement battery is less than half of the cost of a new one, just replace the entire product.
You have to account for the microchips being worked every single day, trying to keep battery juice floating above the level of completely dead. Sensors regulate flow with circuits constantly to keep the product alive, 24/7.

In the consumer/SMB market, APC is a more aggressive brand, overall, compared to Cyberpower; but at the end of the day, they both do the same thing.

Remove battery and check with multimeter, will help confirm if it's indeed a bad battery. Should read like 12.7v give or take. If it's like 11ish it's most likely got a bad cell or something.
