I have the following UPS:
APC Back-UPS ES 725 (https://www.apc.com/shop/us/en/products/Back-UPS-ES-725-Broadband/P-BE725BB#)
Yes, ancient, I know, but it still works. The battery inside is almost newly replaced and I've measured the voltage coming out from it with a multimeter and it says 12V, so it's OK, right?
My problem is the following: whenever the mains power fails the UPS goes crazy beeping and alerting me that the battery is completely drained (it's not, it says 100% charge before this) and the PC shuts down, even if the power fails for as little as 30 seconds. The UPS is rated for a maximum of 450W of run time for a total of 4 minutes and so seconds (please refer to the link given before), and my components don't draw that much power, not even close, but the UPS acts like the battery drains immediately and proceeds to shut down the system almost 5 seconds after the mains power fails.
This happens wheter I use Windows to manage the UPS or the official APC software (PowerChute 3.1), both do the same and I don't understand why I'm not getting more time on battery since my system is light on power draw even at full power.
OS: Windows 10 21H1, latest build at the time of writing this.
CPU: Core i7 3700K (77W, not overlocked)
GPU: GTX 1050 (75W)
The rest of the system consumes so much little that isn't worth mentioning here, just a couple of standard HDDs and a SATA SSD.
Thanks in advance.
