In my experience batteries die after about 4 years.

No UPS that I owned could tell that the batteries are bad, I find this when the UPS power is
disconnected and the UPS shuts down soon (often in seconds).

You can test the condition of the battery by periodically removing the power input and see how long
it actually runs down to, say, 20%.

Vendor software usually has a "test" feature, don't know if nut has this.
