I'm considering replacing the UPS at my router. Some UPS "destroy" the battery too fast.

Yes.  Rather than spend time investigating it, I've taken the approach

I suspect the problem (rationalized by the manufacturers) is trying to
bring the battery back to full charge ASAP -- as well as keeping the
highest state of charge that the battery can support.

 And trickle charge continuously.

Charging at a slower rate and to a lower float voltage would

 Indeed.
 I saw in an Eaton model they mentioned two strategies - translated from Spanish:
 UPS Topology: Standby (Offline) or Standby (Offline) 

{Phrase translated by DeepL, so inconsistent: Topología UPS: En espera (Fuera de línea) o Standby (Offline)}

 Eaton Ellipse ECO 650 IEC SAI Offline 650VA 400W
Eaton P/N: EL650IEC
  I still have not investigated.

I have investigated. There are two models, IEC and DIN. It refers to the connectors.

I do not see a reference to that "topology" except at the vendor. But it says that the expected battery life is 4 years.
