Should I Replace the Battery in My CyberPower UPS or Is It Time for a New Unit?

I have a CyberPower AVRG750U UPS that's started shutting off randomly without any power interruptions. Even when nothing is plugged in, it still powers down after a few hours. It's about 8 years old, so the battery is likely dying, but how can I tell if that's the issue? I want to avoid replacing the battery only to find out that the entire unit is faulty. Any advice would be appreciated!

From what youโ€™re describing, it sounds like the battery isn't passing the voltage check. Definitely a good sign to look into a battery replacement.

New batteries usually cost about $50-60 for a good name brand or even less for generic ones. Just make sure you pick a high rate battery designed for UPS systems to prevent any short power drops, which could harm your hardware.

Iโ€™d recommend replacing the battery. If itโ€™s around 8 years old, itโ€™s likely past its prime. A new battery is generally easy to find and can save you from buying a whole new UPS.
