Best practice for the UPS after the connected PC or device is turned off

[andreiguird_apc]

Which is the best practice for the UPS after the connected computer is shut down?

1) Turn off the UPS but let the UPS still plugged to main outlet (keep charging the battery)

2) Turn off the UPS and also disconnect it from main outlet (the battery would discharge slowly in this state)

3) Let the UPS keep turned on.

I have tried the 1st one, the UPS will keep getting warm while it's turned off. Would this affect longevity of the components inside?

For the 3rd one, if I'm not in home and there is blackout, the UPS will turn into battery mode and the battery will keep discharging until it's run out. If it often happens, would this reduce the battery life greatly compared to 2nd method ?

Hi,

Option one would be the best. The UPS will keep the battery at an optimal charge level and no it will not affect the longevity of the battery or UPS.
