Batterie in or out the cam when on power adapter?

[Ewf2001]

I have three Arlo ultra camera's and one inside is on constant power from the poweradapter. What is best practice, leave the batterie in or take it out?

My base station (and router) are connected to a UPS, so I still do have internet/wifi when the power is lost.  So I keep the battery in on the camera that is AC powered - so I'd continue to get alerts if the power were to fail.

If you aren't using a UPS then it really shouldn't matter.  You could leave the battery out I guess.
