Elite 30 V2 As UPS - Battery Life

Using an Elite 30 V2 as a UPS for my computer and TV.
Pulling an average of 300 watts.

I have a backup generator to my house so the longest I would be without power is 5 minutes.

Does having the power station on AC input power long term affect the lifespan of the batteries ?

The lowest capacity the batteries would drop to would probably be around 95 to 98% while waiting for the generator to kick in.

I switched to the Elite 30 V2 over a standard UPS to avoid having to replace the UPS batteries about every year.

Thanks for any input you can provide.

Please rest assured, this usage pattern has virtually no effect on the battery’s lifespan.
